TS-2000 No TX/RX Possible Repair on November 14, 2012 Strange coincidence on two TS-2000's mine and a friend 20 miles away. Both TS-2000's had an intermittent problem. THE EXACT SAME PROBLEM!

• Kenwood Ts 2000 Discontinued
• Kenwood Ts 2000 Control Software
• Kenwood Ts 2000 Instruction Manual

(With D-SUB 9-pin female connector for the TS-2000(X). [KENWOOD] [TS-2000 Update] [TS-2000 Update] 2) Select the serial port you will use.

The radio would work fine then all of a sudden, it would stop TX and RX. Display worked fine, it continued to switch bands, frequencies and everything was still lit up. You would shut off the radio and turn it back on and it would start working normal again. Kept hearing a relay chatter every time this happened so took off the top cover where we heard the relay and the noise, there was a relay near the speaker.

I even asked on several online forums for help. SO there the radio sat, speaker removed with an external speaker hooked up just waiting for the radio to stop working. Sure enough, it stopped, with the slightest of pressure, touched K201 and the radio started working again. It did this multiple times over the next several days. You could press the K201 relay back and forth and make the radio cut out just like it did on its own. Cold solder joint on the relay leg right?

There was A LOT TO DO to remove that board to get to the bottom of K201 and just re-solder the legs, so it took a few extra days to set aside time to do it. Finally a day with nothing to do and plenty of time.

Here is the fun part: The very first screw removed to take off the board was for IC-202, which was to the left of where K201 was and mounted under the speaker. When this screw was removed, something was odd, ALL THREE LEGS barely had any solder on them and all three popped up off the board!

SO before removing anything else, CAREFULLY cleaned up IC-202 and the board, re-soldered the three legs and fired the radio up. It worked perfect, I would press on the K201 relay and the radio would not stop working. NO WAY THIS COULD HAVE BEEN THE PROBLEM!!! My friend immediately took his radio apart and IC-202 had a bad solder joint as well, he re-soldered his and IT WORKED!!! I never thought of posting my results because we were just happy the radio worked. I received an email from KF7SN who asked if the problem was ever solved because he sent his radio to Kenwood with the same issue, I believe he stated 3 times and multiple $$$$$ with no joy in the repairs.

I will let him tell his repair history. So I sent him an email with the picture and location of IC-202. I also spoke with him over the phone.

Told him how easy the repair was and should only cost him time and a few drops of solder. He said after many failed repairs from Kenwood, he put the radio in storage and just wrote it off. He said it would be several weeks before he could get to the radio and try the repair but he would let me know. Curiosity must have got the best of him, because a few hours later I got this email from Geary: 'Thanks William, sure enough that Voltage Regulator was not soldered to the PCB at all.

And I took it off and resoldered it to the board and brought the rig back up stair from the basement and it works fine. I took it very easy going down and up the stairs but I had to check out that IC #202. Thank you so very much, now I have a Radio, a TS-2000 back on the air and it did not cost me a thing. Unlike the last few times it was sent in for repairs.' I hope this simple repair will bring some failed TS-2000's back to the air!

This article has expired. No more comments may be added. TS-2000 No TX/RX Possible Repair by on November 14, 2012 I LOVE stories like this! TS-2000 No TX/RX Possible Repair by on November 14, 2012 Thanks so much for posting this article. This is just the sort of information hams need to share. Whether you own a TS-2000 or not, the description of the problem and the repair opens up the mind to one more possibility of the cause of a malfunction. Today's transceivers are so very complex that in spite of high reliability components, the likelihood of a failure due to poor assembly becomes much greater than in the past.

Thanks again for sharing this very interesting article. RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 Thanks for posting this information. Hopefully this post will help others down the road. It sounds like this could be an indication of poor production quality control and inspection processes. I've sent Kenwood equipment back to the factory for repair more than once and received the equipment back with the exact same problem. In one particular situation I sent my TS-2000 in twice for repair, along with a carefully written letter explaining the problem.

Each time I'd get the equipment back with a letter from Kenwood saying they could not find my explained problem and the unit was found to be working properly. On the third time around I finally was able to talk directly to the Kenwood Tech that worked on my TS-2000 (no easy feat) and walked him through finding the problem (unit wasn't keying an external amp on the 2 meter band). After much aggravation, mailing/insurance costs, they finally fixed it. TS-2000 No TX/RX Possible Repair by on November 14, 2012 Based on KF7SN's experience maybe you should let Kenwood know. That way more people won't waist money sending 2000's in for repairs that won't happen. RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 The info was sent to Kenwood. I submitted this article for eHam approval on October 11 and was just approved today, November 14.

I had also posted it on yahoo groups, QRZ, MODS.DK and various other sites and have received 4 emails from users who have had their radios sitting because they did not work and this repair brought the radio back to life. Seems like a common problem and I hope a lot more get their TS-2000 back on the air. TS-2000 No TX/RX Possible Repair by on November 14, 2012 Very helpful article.

I have experienced similar intermittent problems with one of my two TS-2000s. I will open up the rig and see if I have the same issue. Thanks for posting this.

TS-2000 No TX/RX Possible Repair by on November 14, 2012 EXCELLENT information. Thank you for sharing this! I am looking at getting one of these soon.so. This could save me a lot of frustration and time.

TS-2000 No TX/RX Possible Repair by on November 14, 2012 Honestly, after having seen 2 TS2000's fail and Kenwood service center return back both units stating that it is unreliable/uneconomical to fix, i will not recommend purchasing another kenwood. The radio's were used in a Dxped environment for 2weeks. They returned the unit stating that they see evidence of corrosion at the connectors etc. The first rig would put out only 10w on HF.

They said it 'could be a problem on the control board' and 'could result in corrosion in the interconnects for other boards'. The second rig had white noise on Rx for all bands, but full power out on Tx. The same story about corrosion. None of the other rigs that were used in the Dxped died in such a manner. Kenwood quotes superior air circulation in the product to the failure as compared to the other radios.

I say, it is crappy design and poor choice of connectors that were probably not gold plated to reduces COGS. Oh well, i used to love kenwood from the days of the 130s, 440s, 850. But now i am afraid to touch one.

Good luck to those owners who are able to fix the units. Krish w4vku RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 Gee, this looks familiar. Seriously, Bill, just wanted to thank you again for giving me permission to use this in my club newsletter (after it had been posted elsewhere. And I owe you a drink from the barkeep.) I've had a lot of positive feedback over the article from some of the club members, and I think that there are going to be 1 or 2 more TS-2000's with a new shot at life because of it! 73 TS-2000 No TX/RX Possible Repair by on November 14, 2012 Since many 2000's do not exhibit this problem, it makes me wonder what production run was involved? Posting the production year(s) would be of help to other owners. TS-2000 No TX/RX Possible Repair by on November 14, 2012 This is not an uncommon type of problem with many radios.

I have a Kenwood TR-7950 2M radio that had intermittent transmit for a couple of years after I bought it back in the 80s. I finally took it apart and found the entire transmit board was one large mass of cold solder joints. I resoldered every connection and voila - the radio still works FB to this day!

I also have an Icom IC-V8000 that had intermittent audio that progressively got worse. I read a post under the reviews here on eHam that the problem was traceable to IC-9, the AF output amplifier IC on the Main Board, which had cold solder joints on its legs. Resoldering those connections fixed the radio and also increased the audio output in addition to eliminating the intermittent audio. It seems that manufacturers don't always do a very good job of inspecting assemblies for cold or no solder joints. This is even more of a problem nowadays with automated board assembly and soldering techniques.

I will file this away for future reference on my TS-2000 and may even open the radio up one of these cold winter days to check it. Hopefully this problem was with older production runs and mine, that was built earlier this year, will be OK. But the knowledge is now there, so a fix will be easy if necessary. Greg - N8GD RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 Great article. I have a TS-2000S/X and although it doesn't exhibit the problem you describe (thank goodness), articles like these are a godsend to keeping our gear up and runnig for years to come. Someday someone may pick up a TS2000 that has this problem and with this info, it can be fixed and put back on the air. Possibly at a low price for the new owner.

Knowing these little bits of info helps when shopping for used gear. Gene W5DQ RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 Not ham related but when I was a 'Mr.

Goodwrench' the 1986 and up Buick Regals with the TV screen for the radio and AC control was bad about going blank. There was a regulated power supply/converter box just above the gas pedal under dash that would quit working. Pulling them out taking the cover off and re-soldering all of the connections on the board would fix every one of them. It's not just radios that are prone to cold solder joints, modern automobiles have them also.

73 KB9TMP RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 Kenwood over the years has issues with SMT solder joints. I have a TM441A 440 FM rig that had SMT chip resistors develop failed solder joints.

These 2 resistors are mounted under a to3 regulator transistor (Q205 on the processor board for those with a TM 231/431/531/241/441/541 schamatic). After many hours of systematicly resoldering every SMT joint on the processor board, when these 2 resistors were re-solderd, no more display failures. I have never seen such a failure in my old trusty TS-820S or my Icom 751 with big fat old school components. With the old 820, it been oxidation between IC chip legs and their sockets, an easy find/fix. Think of this, the coefficient of thermal expansion between a carbon SMT chip resistor (and many other parts like relays) is different from the circuit board, and after years of warm/cold, the solder stress cracks, and a function fails or a dead rig. 'The more features it has the more there is to go wrong'- My father use to say this about new cars and appliances, he had NO idea!!

I truly think SMT is planned obsolescense. If thermal or flexural stress fractures of the soldering doesn't get you, oxidation, or tin whiskers in the IC chips will. AF6AU JML RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 One thing I would like to mention since you talk about heat, It has always ran hot since I bought it new. My buddy who had his TS-2000 also said his ran hot so we accepted it as 'normal'. After both radios had this failure and both have been fixed, they both seem to run cooler. No actual testing, we just know that we can place our hands on the radios and no longer feel the heat.

RE: TS-2000 No TX/RX Possible Repair by on November 14, 2012 This is why I don't get rid of my Drake TR-4C and Kenwood TS-520S!!! TS-2000 No TX/RX Possible Repair-address Kenwood! By on November 14, 2012 Hey guys: It is ALWAYS good to voice serious flaws about radios here and everywhere hams read reviews. However, you MUST TELL Kenwood about it too!

They are big boys and they need to know they have a production issue so it can be corrected at time of manufacture. Too many hams bellyache about this or that and sell off the gear but never address the real situation-tell the builder about the problem and give them the chance to fix it properly and make nice-nice. I've had a good run with Kenwoods-actually better than all the other mfg combined. If the 2000 has flaws-help them make right by us and the downstream production of the model. Thanks, 73 RE: TS-2000 No TX/RX Possible Repair by on November 15, 2012 As far as the thermal expansion mis-match: that's a big culprit, with SMT - no leads to take up the difference.

Also, with the environmental pressure to eliminate lead in electronics - new equipment built with lead-free solder will be more likely to develop cracks in solder joints. That's why in my day job (military avionics), we still use leaded solder! RE: TS-2000 No TX/RX Possible Repair by on November 15, 2012 SMT parts work very reliably for years IF they are properly soldered. Kenwood seems to have issues with their board assembly and soldering processes. Kenwood owners who find issues such as the poorly soldered voltage regulator should let Kenwood know right away.

I have had many SMT boards built at board houses and there are, unfortunately, many ways a board house can mess up an SMT board. All it takes is one tech who doesn't pay attention and you've got a bad batch of boards! Rick, N4FBW RE: TS-2000 No TX/RX Possible Repair by on November 15, 2012 Notify Kenwood that they have SMT soldering issues? The issue goes back nearly 20 years! Kenwood's worldwide service center records tell the story to their Q.C.

Engineering Department every time they fill out a computer based A.R.M. I think their quest for 6 Sigma ends after 90 days to a year after ship date (for those in the know.). But this is NOT only Kenwood, the other makers have the same bugs too. Did you think Icom thought the IC-751 would outlast the memory battery? My TM-441A is 1996 vintage, and they want it to die, after all Kenwood, or any other company exists by selling NEW gear.

They want it to fail after some time, just slightly longer than the other popular competitors. My work QTH is 5 miles from Yaseu/Vertex's California service center. I have been there in person to the service counter, with a 5 year old FT-817, and ended up scrapping it because of a processor failure.

Even though it's still made, they pro-rate the age against the cost of repair. If the cost of repair is 1/2 or more of the rated value of the rig, it's done. 3 hours labor plus parts exceeds the value of a 5 year old current model 817. Of course Icom drops the IC-706 because they up-sell to the 7000. Imagine a world where wine glasses never cracked, car tires and brakes never wore out, a dream?

The sad thing is that a $10,000 rig has more probability to failure than a $900 one has today. Whatever rig you buy, minimise temperature changes, minimise humidity, minimise motion and shock, minimise power supply glitches and voltage variance, pray if you must, and gamble a bit. Sorry for not focusing on the TS-2000 thread guys, I just think this issue flows into about ALL MAKES AND MODELS today, and beyond radios too. Be wary, and careful out there. AF6AU JML RE: TS-2000 No TX/RX Possible Repair by on November 15, 2012 Yep, ALL brands have troubles, Some models more than others.

Thanks for posting this, Great FYI for TS2000 owners! TS-2000 No TX/RX Possible Repair by on November 15, 2012 Bill, Your findings motivated me to open up my TS-2000 to see what could be done for couple of intermittent problem I’ve had with mine for the last 6 months. One was identical to what you described. The second involved the receiver pre-amp (30 KHz-21.5 MHz) failing after several hours of operation. After removing the top & bottom covers, reconnecting the power supply and a service monitor to the HF antenna input.

I removed the speaker, applied power, injected a signal (21.150 MHz) and began tapping with a plastic tuning tool in the vicinity of K201. Immediately the received signal began to drop in and out. I then moved to IC-202 (TA-7808 3-pin regulator) whereupon I discovered none of the leads soldered to the board. Re-soldering those connections cured the problem.

I decided to move onto the receiver pre-amp problem. I flipped the unit over to expose the TX-RX board. Tapping the board in the vicinity of Q12 caused the pre-amp to fail intermittently. Moving to the vicinity of R65 caused the pre-amp to fail completely.

A hand magnifier revealed one end of R65 to be barely making contact with the solder pad. Powering off the rig and using a pair of tweezers, I was able to completely remove R65 with almost no effort (it was barely making contact on either end). Re-soldering both ends of R65 cured that problem as well. Looks like lead-free solder (or improper technique) is probably the culprit here. Without going through my records, I cannot pinpoint when I purchased the rig. But I think it was around the year 2000. Mine is serial number 30700103.

Again, thank-you for a very informative article about the TS-2000 problems! 73, Rod N8RAT RE: TS-2000 No TX/RX Possible Repair by on November 16, 2012 LoFoTheSS Look For The Simple S. ESPECIALLY when it comes to connections. One of the PRIME tools any tech should have is a wooded dowel. Used to tap on a circuit board or otherwise disturb components safely (NOT in any HV areas, of course!) Sometimes it's a manufacturing fault, like cold solder joints.

Othertimes it could be a component fault, like a lead that didn't take solder because it wasn't clean. Sometimes it's a design fault.

Like Tandy 1000's that used a connector on the power supply board that should be used in a plated through hole. Only trouble was the Tandy 1000 had a single sided PCB in the power supply. As a result, the power connector could flex on the board and the pad would 'lift off' the PCB. This wasn't usually a problem, as long as the unit was stressed enough to tear the trace. But sometimes the connection would develop a 'ring' crack around the connector pin.

And for another strange reason this seemed to happen to the +12 more than any of the other pins. And if the +12 line went intermittent, the hard drive or floppy would go 'not ready' for a fraction of a second. What was really a wrench in the works was if you took the machine apart, just moving things around seemed to make the connection 'go good' and you couldn't find the problem. Put it back together and it would work fine, for a couple of weeks. Then start up the intermittent 'drive not ready' errors. TS-2000 No TX/RX Possible Repair by on November 16, 2012 These kinds of issues are why I never buy new. Radios have gotten smaller and smaller and harder to work on.

Newest radio I have is a TS-430S and works everyday. 73 TS-2000 No TX/RX Possible Repair by on November 16, 2012 UPDATE: I purchased my TS-2000 new in March of 2002. Curious if this problem might be something confined to any particular production run of these rigs. TS-2000 No TX/RX Possible Repair by on November 16, 2012 Hello William W6GQ look what we started lol, its great that so many people have had these same problems and you found the problem and got this repair rolling.

If I had not email you my TS-2000 would still be sitting on the shelf. Many thanks again my friend for all of your fine help. And I hope very much we can connect on air some time and have another chat like when I called you via the twisted pair. Many thanks again and my God Bless. 73, Geary KF7SN Billings, Mt. RE: TS-2000 No TX/RX Possible Repair by on November 17, 2012 N2TMC.an issue like this is anecdotal, and not a commentary on the reliability of modern gear.

I'll stack up my modern rigs against anything I've previously owned over 35 years. But do what you want. TS-2000 No TX/RX Possible Repair by on November 19, 2012 Thanks to Williams article I have my TS-2000 back at its operating position. The problem he describes was the exact same issue that he mentioned but I was able to fix the radio myself.

Thanks again William for the valuable information. 73, Kevin - KG0MN RE: TS-2000 No TX/RX Possible Repair by on November 19, 2012 I wonder if 'Geary' attempted to get his repair $$$ back from Kenwood seeing how they charged him for work that never actually repaired his rig? I've always had very good results from Kenwood's repair facility but this is just an utter disgrace, and I'm afraid I'd have something to say to them about this is it were my TS-2000.

However, this is great info to keep in mind of this ever happens:) RE: TS-2000 No TX/RX Possible Repair by on November 21, 2012 Just think of what the ham radio economy would be like if every ham built his own stuff and held onto his rigs for for his lifetime. We wouldn't be able to buy anything because there would be no manufactures out there making anything! We ran 'em out of business! Sure keep your old rigs, cool, I wish I would have, but at least Invest in technology every 7 yrs. They are not all bad.

At least we'll have companies around making radios other than the chinese. I see the end of the Icom, Yaesu and Kenwood amateur divisions just as soon as Wouxun comes out with a hf / 2m / 440 rig for around $500. It's only a matter of time, they need to wake up and realize That we don't need $500 ht's with gps. (unless we are hunting for sasquatch) We get along fine with one that costs $200 or less. The days of the ridiculously high priced rigs are numbered. I deal with smt at work, it's a royal pain, literally I get migraines at least twice a week using the magnifiers. This was a great article though, much appreciated!

73' RE: TS-2000 No TX/RX Possible Repair by on November 21, 2012 WB4DX. John, I was right with you until the '$500 GPS HTs' and 'ridiculously priced' gear remarks. New gear today is very affordable, especially when making a real dollars comparison to gear pricing in the past. Wouxun won't be able to offer a rig that will have the quality and features of an Icom 7600 for $500.it just won't happen. Also, not everyone is buying an Icom 7800 or ID-51 (when it's offered).

Great points about supporting current manufacturers.they're producing some very nice stuff, while operating on very slim profit margins compared to some of their other divisions like biz band and avionics. 73 and cheers. TS-2000 No TX/RX Possible Repair by on November 23, 2012 Theres nothing more frustrating than an intermittent connection. Those will drive you nuts trying to figure out. The worst ones are those that wont replicate the problem when you want to repair them.

It usually will only do it when you least expect it.like working a rare one. Good job on the repair and good advice to those who own a TS-2000 with this issue.

RE: TS-2000 No TX/RX Possible Repair by on December 4, 2012 Early model serial number TS-940s were notorious for soldering issues on the power supply board and elsewhere. Don't buy one with a number lower than about 6 million, if memory serves. Philip KA4KOE RE: TS-2000 No TX/RX Possible Repair by on December 6, 2012 '.Of course Icom drops the IC-706 because they up-sell to the 7000. ' Be careful what you read; it may not be true.

The reason for most equipment being discontinued is due to unavailability of parts from suppliers with no acceptable alternative available. The IC-706 series had a life in the order of 15 years. This is an incredibly long time in modern manufacturing. TS-2000 No TX/RX Possible Repair by on December 9, 2012 Although my problem was with my first rig, the TS-820S that I bought new, I had myriad cold solder joint problems with this radio, too many to mention in this post.

It was not confined to one area or board, it was with multiple boards and throughout. I say this not to distract from the thread, only to amplify the message of cold solder problems in at least two of these radios. RE: TS-2000 No TX/RX Possible Repair by on December 9, 2012 VA1CQ has a point. There's already problems with older FT-817s and availability of some parts.

Most companies have 'rules' about the parts. Like all chassis parts need to be available while the unit is in production, then main chassis for so many days after production ceases. This becomes confusing when units are still in the stores and warehouses but from the factory point of view, it's a dead unit. Then there are times when manufacturing can't get parts to build new.

Sudden discontinuing of the product. However a LOT of companies make their 'repair parts' purchases at time of each production run. The only problem with that is what can happen when parts expire. Batteries for Radio Shack HTs are a prime example.

They bought a big lot of batteries that aged in parts till they were almost dead by the time customers started needing them. And every manufacturer can have problems when technology changes. Not just of the product, but manufacturing technology.

When Radio Shack came out with their first digital scanner, the COMP-100, it was incredible. But within months of it being in customers hands it was a nightmare.

Thank God it was a 'one-shot' and quickly replaced by the PRO-2001. When the COMP-100 worked, it was absolutely incredible. But the problem was the circuit board for the controller was so dense it cracked the vias and became intermittent when it was turned on and off.

Coupled with a poor lacquer to 'seal' the board, it would swell depending on humidity. I fixed my COMP-100 and it was rock solid.

But it was a lot of work. I baked the control board in my oven at about 120 degrees overnight, then the next day spent the day soldering wire-wrap wire through every via. Took three tries till I got it working right, then I sprayed the board with clear lacquer. I ended up selling the thing years later to someone who wanted 'that' scanner. It was still reliable.

Remember that if the EQ is not as you like it, step up to the plate and download the FULL VERSION. This should give you an idea of the increase of the RX BANDWIDTH that you will gain using the EASY USE version. The TX BANDWIDTH will extend to 3.3 when you set the MENU (22) to 3.0.

This will help your TOP end EQ audio frequencies. Please be sure not to be a frequency HOG. If you are contesting or down in the 75 METER DX WINDOW, back the MENU down so you are not interfering. Here is the BOTTOM LINE. The KENWOOD algorithms are 'secret code or something'.and I not sure why. There are no help files listed or available from KENWOOD and when I tried to get information from their technicians, they simply told me this was not available.to anyone but KENWOOD certified technicians.

There are no help files for any of the MODIFIER programs. The EXPRESS version is the best way to go if you are not a computer GURU. I did notice that the memory offset markers highlighted in YELLOW make the most difference to the EQ setting. That means 10001000 or 20002000 or 300030000 up to F000F000 will get you started. You cannot do this without a spectrum analyzer to see the curve as shown above.

However using one of the available computer audio spectrum programs (Sound Card Oscilloscope) you might get closer than a mile.Throwing numbers at a wall will accomplish nothing. You should analyze the files included and listen to the results. Too mich bass, to much mid, pinched sound in the high end, whatever and then go from there. There is another application that may help you. I will post it at the end of this article.

Remember these mods are NOT firmware updates, they are nothing more than a FILTER COMMAND when in USER MODE under MENU 21 and 22. In other words, no matter what you do you cannot hurt the radio, and, keep in mind, you do not have to open the radio. If you do a full radio reset, you will return the radio to USER MODE all ZERO's and the DSP Modifier will have to be executed again.

This also removes any MEMORY PRESETS you have placed in the radio, so as you can see, the DSP Modifier does no more than send a MEMORY SETTING to the offset for the 'USER' DSP. Give it a try.you have nothing to lose and you might stumble on a great EQ setting for that D-104 you are using. The FULL version listed below requires TRIAL and ERROR for the best results. Have at it and see what happens. THE FULL VERSION: READ FIRST: If you have not setup your SERIAL CONNECTION do it now.

READ SECOND: If you have not verified communication with your Kenwood.STOP. There are no directions available for the FULL VERSION, so I will get to it for you. I recommend this modification program over the EASY USER version because you have better control of the results. Later, on this page, I will explain the SERVICE MONITOR application. After you have downloaded the FULL VERSION from above and installed it as required, turn on your 2000 and execute The DSP-MODIFIER program. You will see the screen to the LEFT. The CONNECT RED INDICATOR SHOULD BE ON.

The com=port should match your PC and the BAUD rate should match MENU 56 on your 2000. If all is properly set you are ready to use the program. Before you make any changes, select the DROP DOWN MENU in the 'Command Viewer' panel. I recommend you start with N3GX PRO. You will see a series of 2 BYTE offsets in the blue box. Since the EQ is a 16 bit adjustment, OFF will display all ZERO's from 01-16. Note that all 16 offsets are changeable.

NOTE: N3GX GOLD is designed for the HEIL GOLD LINE microphones. You may adjust any of the OFFSETS for best match to your microphone for your voice. The procedure is time consuming. To edit one of the lines, you select that line in the DROP DOWN box and enter 0-F (16 bit offsets) in the (2) 4 BYTE registry editor box and click 'Accept Changes'.

The OFFSET FILE is a TXT file, but it is not located on your computer and you must create one. In the command viewer, select 'OFF'.

All the offsets will read '0'. Now select a line to edit and 'Accept Changes'. Problem is.This may or may not work depending on the Service Pack installed on your XP system. It may not edit at all in Vista or Win 7. NOTE: I found this to be the SLOW way to accomplish the results you are looking for. So I recommend using the NOTEPAD editor. Follow along as explained here.One more thing I noticed.the 'Update' GREEN indicator will flash on and off and never stop.

Before you click 'Update' uncheck 'Auto'. The offset will be written in 2-3 seconds. Forget the EDIT LINE pane because it is truly a PAIN.Select 'OFF' for all '0' and and click 'Save' 'FILE'.

Now give this file a NEW NAME. ('EQtest01' would be a good name.) and save it to: C: Program Files DSPmodifier on your system.

Now open that file with NOTEPAD, you will see a string of '0' across one line. Remember that each line is (2) 4 bit segments or 1 BYTE. To modify line 3, count 16 '0' positions and replace the next 8 BITS with your entry.

SAVE the file and in DSPmodofier click 'OPEN' file. The offset you created should be your entry for line '03'.

NOTE: I have added a small file for you to download.txt is located on this website. This file is simple. It uses 0-F for each SEGMENT. You can save this file to the above address and click 'OPEN' select K3HKR01 and the results will appear in the blue box above.

If you 'OPEN FILE' K3HKR01.txt, you will see 8 BITS, '0' - 'F' in each corresponding SEGMENT of the MEMORY REGISTER. Yes you could write this to your 2000, it will not hurt anything, but you may get very strange audio reports. Using your NOTE PAD, replace any of the SEGMENTS with any 8 BIT combination '0' through 'F'. Save that file with a new name ('EQtest02'). Now 'OPEN' that file and verify your changes.

To begin.I suggest you use 'N3GX PRO' as a starting point and 'Send Command to Radio'.Check your settings and be sure that you set MENU 21 and MENU 22 ('+'/'-' key) to 'USER'. Now listen to the results on a separate receiver or have a friend listen and report. NOTE: Please use your dummy load. If you have any computer savvy you can do this after about 2 hours of experimentation. Using an oscilloscope will help, or use one of the 'sound card' scopes available on the Internet.

If you would like to upload your file settings to the website for others, simply send the.txt file to the WEBMASTER. I will archive it and place it here for others to use. To Be Continued. If you can add something here, please email the WEBMASTER.

MONITOR APPLICATION: Kenwood TS-2000 DOWNLOADS: (1) The SERVICE MONITOR 20MB (2) The ARCP-110 Control Program. 5MB (3) The TS-2000 Service Manual 25MB INTERFACE: HOW TO USE The INTERFACE for your TS-2000 is well defined in your user manual. The DB-9 connector is located at the LOWER LEFT hand side of the rear panel. In your manual the location is noted on page 13 of section 4 and it is clearly shown. There are no fancy plugs to buy and certainly nothing too serious about it's use.

The functions are explained on page 50, while the connections for additional data ports is explained on page 93. Here is where you may become confused, if you are computer savvy you will certainly understand that the COM PORT on your PC is also a 9 PIN connector. This connection may be found on the rear panel of the MAIN BOARD or a separate PCI interface that supplies 1 or 2 of these ports. Many early computer models maintained a serial port, however today's models, especially lap tops do not. Today the standard is USB and it too becomes a slippery slope for the computer novice. If USB is your only alternative, follow these simple instructions.

If you have a DB-9 on the computer, you only need a FEMALE to FEMALE direct connection serial cable. (1) Purchase the KEYSPAN USA-19HS USB to SERIAL adapter. This will extend your USB out of the computer and allow proper handshake to any serial device that uses DB-9 connector.

NOTE: There are other units on the market and Radio Shack has one in it's catalog. This one does not work!! Some of the other less expensive units may function, but these are not RF friendly and they also radiate big time, causing EMI interference on your favorite frequency (especially VHF). Do not waste your time or money, go get the KEYSPAN. (2) Now you have a DB-9 connector, but note that you have MALE pin-outs on both.

The radio and the PC (or your KEYSPAN) will look identical and that ain't going to cut it. You need DB-9 to DB-9 straight through cable. Here we go again.You can purchase one of these, but they must be pin to pin identical and that is often not the case. NOTE: Radio Shack has a DB-9 female to DB-9 female cable that will work fine. However it is expensive and you can build one cheaper if you are good with a soldering iron. Purchasing a FEMALE to FEMALE cable will be a caution.

What you get is a molded cable that in most all cases has PINS 2/3 reversed on one end (3 to 2). This is normal for most applications, but not 2000 CAT. Here is how you can get around this problem. You need a FEMALE DB-9 to FEMALE DB-9 cable. As noted, RADIO SHACK has these cables, but you can purchase everything you need for far less.

Two connectors, two covers and 3 feet of (20 Ga.) 10 wire serial cable and two EMI snap chokes. All this is available at most electronics stores and yes at 'The SHACK' (3) Now carefully design your cable and be sure to include EMI chokes on BOTH ENDS. You must wire each pin direct. That is PIN 1 to PIN 1, PIN 2 to PIN2 and so on.When you are completed the last wire remaining should be connected to the shield. That may be the actual shield that is around the jacket of the cable. NOTE: I did not have a shield, so if simple removed the shield from RG-8X and slid the DB-9 cable through the shield before I started wiring.

Take a look at the connector above, PIN 5 is SIGNAL GROUND, that is not CHASSIS GROUND, because SERIAL LEVELS are not TTL levels and you must be sure that you do not confuse SIGNAL GROUND with chassis ground. (4) Ok you should be ready to test your cable and set up your radio connection, but before you do, just in case you have a DB-23 connector on your computer (I certainly hope not) you can search the Internet for cable pin-outs.

I will add a cable pin-out image here ASAP. If you have no other choice, I suggest you upgrade now! Sorry about that.To continue you must understand your serial ports. On most XP class computers (and above) there will not be a DB-9 connector, so have your KEYSPAN installed and setup. This is easy, the KEYSPAN adapter when installed and the drivers prepared properly, your USB-SERIAL adapter will show in the 'My Computer' - 'View System Information' - 'Hardware' (tab) - 'Device Manager' (button) - 'PORTS' (Com and LPT) '+'.

Here you should see the KEYSPAN device and the COM PORT it represents (COM 1,3 or 2,4). Now double click on the device (KEYSPAN) and the dialog box will appear. Click the PORT SETTINGS (tab) and be sure to set the parameters as follows: (top to bottom) 9600, 8, none, 1, none. Now click the ADVANCED (button) and select from DROP DOWN MENU, any available COM PORT (1-4).

Click 'OK' and back out. (5) You are ready to set the TS-2000 in MENU 56. Set the COM COMMUNICATION to match the KEYSPAN setting at 9600 BPS. This is all you need to do. NOTE: You need a communication program to talk to your 2000. I suggest the KENWOOD ARCP program or HAM RADIO DELUXE.

HRD version 5.0 is a perfect match for the TS-2000. It is easy to download and install.

You can find the DOWNLOAD link on this website or search HAM RADIO DELUXE on the Internet. The ARCP application from KENWOOD has a few extras that HRD does not, but it looks 'butt ugly' and it is hard to use. HRD on the other side of the coin is loaded with lots of applications that run in the back ground and can be a bit cumbersome.

You make your choice, I personally like HRD.and for this test, it will it is the best application to use. Turn on your 2000 and then execute HRD. The CONNECT screen appears.

Select a connection TS-2000 and assign the COM PORT your SERIAL or KEYSPAN adapter is using to communicate. Select the BAUD RATE (9600)to match your 2000 and then click 'connect'. You will be prompted if something is wrong, else you will see the HRD screen with your 2000 frequency listed there. NOTE: This is not an HRD tutorial.

If the connection fails youhave done something wrong. You are not using a PIN to PIN direct cable or the USB-serial adapter you chose is not functioning. If you set everything as directed, you will have a connection. HRD should read TS-2000, COM(n), 9600, -, X, -, X where the 'X' is CTS and RTS (clear to send/ready to send). There is no error checking for HRD the program 'assumes' the connection is present and maintains CTS/RTS as HIGH all the time. HRD errors will only appear if the connection drops or is intermittent beyond 500MS.

(6) If you can spin the dial and HRD follows, you are connected to your 2000 and all is functioning properly. I suggest you play with HRD.it is not the only way to really enjoy your TS-2000, but it is one very nice interface for the contest user. Virtual sliders, track ball support and bright buttons replace menu and radio functions, and there are a few items you cannot do directly, that HRD can do with a 'mouse click'. (7) Now download the suggested programs and prepare to use the DSP Modifier to set your TX/RX EQ. These programs will communicate and function as explained only when your computer is connected and the 2000 is ON.

If HRD executes properly, your computer and 2000 are communicating as required. PC CARDS: The problem many of us face today is the lack of a SERIAL PORT on the rear apron. Most mother-boards have a set of pin headers that can be connected to a generic HEADER INTERFACE. The one I have purchased that works on Intel Main Boards, is the StarTech PLATE9M. This is available from and can be purchased on-line or at any reputable computer outlet.

You can check out the interface configuration on the website. Simply search the model number above. There is another item you can purchase as well if you need more than one COM PORT. Some of us control two radios and that will require COM1 and COM2 interfaces. If that is your situation you can purchase a PCI-SERIAL interface card, also from StarTech.

The PCI1S550LP is a low profile (single) COM PORT that uses the standard PCI slot. The PCI2S550LP is a dual port card. All information is available on the StarTech website. These work very well and are easy to install into any PC that uses a standard PCI slot. The cable issue can be frustrating. You can roll your own or simply purchase one from StarTech.

The cable must be 9 pin to 9 pin direct. No crossover, female to female. This is NOT A NULL-MODEM CABLE.

It is wired DIRECT all pins 1-9 on both female ends. The StarTech works fine. The Radio Shack cable is expensive, but it will work with any Kenwood. The USB adapter from Radio Shack will not work properly so do not purchase that adapter for the Kenwood interface. Note that the Intel boards will support both these items. I use the Intel DH55HC series main board with 3 PCI slots. I run the TS-2000 at 19200 BAUD with the Kenwood ARCP software almost exclusively.

I update the radio output, frequency and S-meter to my webcam. The serial connection has never failed.

Works great with HRD as well. NOTE: Do not contact me with questions regarding any of the suggested downloads. Please read the disclaimer below. Please understand that Kenwood, N3GX, HRD and K3HKR are not responsible for errors encountered. You make any modifications to your TS-2000 understanding that you alone are responsible. HAVE FUN- K3HKR TUTORIAL - How to use this control program for your Kenwood radio.

The ARCP program written by Kenwood for your TS-2000 is a rather nice program with a few great features that other ARCP's do not have. The single most useful feature is the TX/RX EQ control feature.

This program allows you to create an abundance of EQ and FILTER settings for the DSP your radio uses to enhance audio IN and OUT. There are a few other useful items as well and all of this can be controlled by using a simple interface or serial cable between your computer USB or serial port and the DB9 input to your TS-2000. The ARCP can be used in conjunction with the DSP modifier application. Both are interesting and the DSP modifier allows you to SAVE any setting you create. I will explain the work around for this a little later. There are a few items that you must overlook however.

First of all the program is not very neat, or at least not as neat as the TS-2000 layout or Ham Radio Deluxe ARCP. The interface is simple, yet effective. Some of the buttons are out of place and the display can not be configured. The HELP console is not much help at all.

The display uses an ugly AMBER-PEACH color with a rather simple FONT for the items on the panel. While it is ugly, it is functional and you will find a world of uses for it, especially if you are on CAM RADIO NET. Lets get down to business.you must first have the S/N for the original CD that came with the radio. That is to say, the B-2000 users received the ARCP Ver. 1.02 back in 2001 when the B-2000 was very popular.

The first ARCP was basically the same as today and you will need that CD with the REGISTRATION NUMBER in order to use the latest ARCP Ver. This version contains a few.DLL files that will allow the ARCP to be run with Vista and Windows 7. The early TS-2000 (X) users had to pay 39.95 for the ARCP program CD. This was available from the dealer or straight from Kenwood. You can still get the program, but I suggest you search around a little, the original CD should be out there and available at a reasonable price.

Now that you have installed the original program, download the update and follow instructions to install it over top the OEM application. The latest version is Ver. 1.10, as I mentioned above and it looks like this: This is the ARCP application from Kenwood.Take a minute and look around before I explain this app from top down. Starting from RIGHT to LEFT the menus function like this. The hierarchy is RED, FUNCTIONS are BLUE and SUB MENU COMMANDS are TEAL and BROWN. The TS-2000 button will help navigate to additional resource. File: Exit - This menu selection simply exits out of the program.

NOTE: The recommended way to exit out is to first close the CON and then POWER down your radio. Leaving the COM PORT hanging may leave a few processes running in the background on your PC. Control: ON / OFF - This selection toggles the CONSOLE communications port ON or OFF. Setup - This selection pops up the COM PORT console dialogue box where you set the parameters for your serial port connection to the radio. Set the port to match your computer and BAUD RATE - 9600.

Getting to these functions is easier in ARCP than using the FRONT PANEL on your radio.

If you are using a B-2000 you may not have a control head so the ARCP is the only way to go. From the ARCP, select Radio / Menu and the MENU WINDOW appears as below. The MENU panel lists all your TS-2000 choices from '00' to '62' and includes, in letters, the SUB MENUS. In the picture here we have highlighted the FM MIC GAIN menu and we have set it to MID. In the radio MENU the function requires nothing more than to select the setting.

The change is automatic. To select the RX EQ function, we would select '20' and in the sub selector, our choice from 'OFF' to 'USER'.

Same for the TX EQ. Unless you have a great mind and can remember these MENU choices, this is the best way to make TS-2000 changes. One thing to remember about ARCP programs, they all have limitations. Ham Radio Deluxe has some neat little provisions that will come in handy, but it is not as extensive as Kenwood's program. HRD is configurable, this one is not. HRD cannot EQ your radio, this one can.

You can use the N3GX DSP Modifier, but in order to change the EQ you will have to jump through a few hoops to get there. I suggest you stert here and gain confidence with your radio. I do not believe the TS-2000 will satisfy many users who do not have a computer, it is as simple as that. But, remember the SDR radios like FLEX and others, you have no choice but to interface with your PC, and if yours is slow, well it just is not going to make the grade.

NOTE: There are two types of computer based radios.the SOFTWARE DEFINED RADIO and the SOFTWARE CONTROLLED RADIO. The Kenwood TS-2000 is an SCR. DSP The Digital Signal Processing functions of the TS-2000 are very useful but Kenwood has left some mystery for a few of us to solve. N3GX did some of this for us with the DSP modifier, but he left no tracks to follow. He has no problem with that and I do not either.

He, after all, created the program for himself. He was not greedy but he did only what he needed to accomplish what he wanted.end of story. The DSP AF-EQ functions can be found at radio MENU numbers 20 and 21. They each have five selectable positions plus OFF. The USER selection is one you can design and create personal settings using the ARCP program. First, with the ARCP running, select from the DSP MENU, the AUDIO EDITOR / Samples function. You should have a window pop up that looks like the one below.

There is a DROP DOWN MENU titled (Type). Click on that and select 'High Boost', now use the (Set) selector and choose RX EQ. Now click on 'WRITE' button and confirm the write function. If you are not in the USER MENU on the RADIO RX EQ, nothing will happen. Go to the MENU FUNCTION as explained above and select No. 20 and set the EQ = USER. Now repeat the steps above and you should notice the change almost instantly.

If not, select 'Bass Boost 2' and WRITE. You may play with this function as much as you wish.you cannot hurt anything in your radio. This is just like inserting a frequency into the radio memories. It will remain until changed or you do a MEMORY RESET. (Turn on the radio while pushing the A=B button on the TS-2000 front panel.) You will lose your EQ setting, but in the next step I will show you how to SAVE it to a file and re-call the EQ SETTINGS later. DSP Design Function: From the DSP MENU, select AUDIO EDITOR / Design.

This will initiate the design window shown here. This is way cool, even though it is a bit mysterious. I told you it would be, but if you have ever set up a BANDWIDTH filter this should look familiar.

Kenwood Ts 2000 Discontinued

There are three MENUS to choose from.' FILE' will allow you to LOAD and SAVE all filter design (.UDD) files you create. You can also select an EXIT function from this MENU. The 'DESIGN' MENU offers the 'Filter Type' - 'Cutoff Freq.1', 'Cutoff Freq.2' plus the 'Attenuation'. These functions are all available from the DESIGN CENTRAL window. The 'Set' MENU is the WRITE to radio function that will store your design in the USER RX/TX EQ MEMORY.

Now the MYSTERY.LPF = Low Pass Filter, HPF = High Pass Filter, BPF = Band Pass Filter and BEF = Band Edge Filter. You can select any of these and make a series of adjustments. Each adjustment will offer you changes that can be profound or just simple settings. The first thing you must do is learn how to create a.UDD file and save it. I created a 'UDD File' folder in the Documents directory and that is where I placed the folder. First I created a simple 'TEST.UDD' file which was basically designed from BEF 'Attenuation' = 99 and BPF 'Attenuation' = 99.

I then saved that file as 'TEST.UDD'. Next I created an EXCEL FILE 'UDD.XLS' and made note of the changes. Next I did the WRITE to the radio.it did exactly what I expected, attenuated the receive signal. So what do I do now??

Well you can undo the changes and SAVE a new file, or simply WRITE the old settings to the radio, the signal levels should all return. What you should have learned was making the changes will effect the USER EQ setting instantly, but it will not effect any of the other settings. You should have also noticed that the CURVES changed with these adjustments. These UDD files can be opened and viewed in an editor.

They are basically TEXT files, but that is where it all ends. By saving the OEM files with a filename, I can read these and then check the range of adjustments, but that will take some additional understanding of how Kenwood uses the information in the file and that is the problem; they are not offering this information. TEST.UDD LINE 1 3 LINE 2 1.000 LINE 3 2.000 LINE 4 4.000 LINE 5 1.000 LINE 6 LINE 7 - Note - LINE 8 LINE 9 NOTE: I will try to explain the above, but Kenwood is not going to reveal the information to anyone (I said that earlier) so take it with a grain of salt. So let us continue.The LINES in the above file represent POINTS along the curve. If you look at the SAMPLE window you can clearly see this. The problem is, something is missing in the plot. That is right, the GRID index information that would be listed on the LEFT SIDE of the graph.

In order to PLOT the graph, we need to know TWO index points. The.UDD file seems to be missing the 'Y' information. This is the same for all the plots, LPF through BEF.

However do not read anything into the graph.ATTENUATION will manage (1 - 99) this for you. Gathering more information reveals: LINE 1 represents the filter type, meaning '1' is the LPF, '2' is the HPF, '3' is BPF and 4 will be the BEF. LINE 2 represents the LPF setting (effected by HPF and BPF).

LINE 3 represents the HPF setting (effected by LPF and BPF). LINE 4 represents the BPF setting, but adjusting this setting will also effect the LPF and HPF as well. LINE 5 represents the ATTENUATION setting you chose for your design. This adjustment will not effect any of the other 4 'Types'. I suggest you set the ATTENUATION at '1' for your experiments.

NOTE: You must remember that if you are going to 'Design' DSP EQ files, you should save them with 'TX' or 'RX' somewhere in the filename. (Example: RXTEST2.UDD would be your 'Receive EQ' second TEST file.) I have searched the entire Internet looking for.UDD files. I have found nothing and I don't think you will either because most Amateur Radio operators are not going to take the time to gather this information, let alone offer the results to anyone. You must understand LOW PASS and HIGH PASS filters and how they effect BAND PASS. This information is not covered here because the Internet can do that for us.

Use your browser 'search engine' to find articles explaining Start with the BAND PASS FILTER, it is the easiest to understand. Now try building your own BPF for the Kenwood. Go ahead, 'Write' it to the radio. Did anything happen??? ARCP TIPS: Several of the features displayed above have additional details here. This is the poorest excuse for a RADIO DIAL that I have ever encountered.

There is however a good way to use this button. Clicking on the KNOB (???) will toggle the color GREEN and the knob can be manipulated to turn almost like the real dial.yeah sure, but fear not, if you have a wheel mouse a simple click will activate the wheel and you can tune up or down the band using the WHEEL on your mouse. Better yet.there is a USB JOG SHUTTLE that looks and feels like a DIAL, this can be used to TUNE the ARCP, just like a real main dial. This is very cool if you are using remote operation from your work computer. Is a click away for those of you who have the 'X' radio. If you do not, you will simply be taken to the SPLIT 70 Cm mode with 2 Meters. You can access this menu function using the TX RX/ Satellite selection.

The More about this function in your manual. Radio The real difference for your TS-2000 comes after you make a few modifications. These are simple but they do require some surface mount technology understanding and a good CERAMIC tip, low wattage pencil iron. If you need a service manual, you can get that here as well, from our DOWNLOADS section.

RX/TX Modification: This mod requires you to open the radio. Remove the TOP and BOTTOM covers. Set them aside along with the hardware. If you look closely along the sides of the radio near the front panel, you will see four (4) screws that hold the CONTROL HEAD in place.

Remove these, two on each side. Now carefully pull the control head straight out from the chassis, be careful, there is a ribbon cable (CN4) that connects the head to the control board. The 3 resistors we want to remove are located on this board in the LOWER LEFT hand corner, just right of the FAN. You should see a series of JUMPERS. These are SURFACE MOUNT resistors. You will be removing three of these resistors.

Be careful to HEAT only the resistor. Using a set of tweezers, remove the resistor from each of the SM pads. Now reverse the steps and re-assemble your TS-2000.

For these new functions to operate, you must do a CPU reset, so turn on the TS-2000 while holding the A=B key in. This reset will erase any memories, but if you use the MCP-2000 program, you should already have a backup of those memories and can simply re-program the radio. MODIFICATION DETAILS: (R52) will expand the RX frequencies. This will allow you to hear 220 MHz and a few other frequencies that are useful as SWL or WEATHER stations.

Kenwood Ts 2000 Instruction Manual

You will now receive SUB-BANDS that lie between 118 to 174 MHz and 220 MHz to 512 MHz. This is not an increase in receive potential, but it will allow you some flexibility in the VHF/UHF bands. (R53) will expand the TX frequencies.

Removing this resistor and you can operate MARS or 60 Meters which will be undergoing some FCC changes this Fall. You can operate 100 watts on 60 Meters after the changes and one new channel will be added. This alone will make your TS-2000 more flexible. The new transmit frequencies are: 1.7 - 30 MHz, 49 - 54 MHz, 152 - 152 MHz and 420 - 450 MHz. The additional HF allowance is worth your time and energy. (R54) will expand the special features: These are SkyCommand, External Remote Operation and Cross-Band Repeat.

All of these specific features are listed on the Kenwood website, but basically SkyCommand puts an HF rig at your finger tips as long as you have a Hand Held 2M FM radio to control the TS/B-2000. The next feature is CROSS-BAND Repeat.this function allows you to use the TS-2000 like a repeater. You can operate 10 Meter FM from your UHF 440 handheld. You can operate a SSB net too. The CROSS-BAND function is documented in the user manual.

There is also an EXTERNAL REMOTE function that you can use. From any PC via the Internet, you can operate your TS-2000 at home. Sending commands to the radio can be done by using the ARCP program directly on your REMOTE PC desk top using one of the REMOTE DESK TOP applications available on the Internet. As you can see, it is worth your effort making these three simple mods.

The images above along with this picture of the actual resistors located on the CONTROL BOARD will help you complete the steps above. Start with R53 and then R52. This will allow the solder to be removed and you will have a clean set of PADS if you ever decide to undo these changes. The cable CN4 is the main cable for the CPU and READ-OUT boards inside the head. Be sure not to damage this cable and be certain no solder splashes come in contact with the connector. You are working in a small area here and a little caution will result in a job well done.

Please no 125 watt solder guns in here. I hope you enjoy these modifications. I will listen for you on 60 Meters. K3HKR INFORMATION: and Please follow these links for additional details. Program: The Memory Control is available here.

Download the software and un-zip to a folder of your choice. Using of the program is rather self explanatory. First the 'Menu', where you can look at all TS-2000 menus that are set in your radio. You can make changes from here without having to play with the MENU button on the radio. This is the same as the MENU CONTROL in the ARCP application.

Set the KEY ILLUMINATION on the fly, and turn it off during daylight hours. Set the SIDE TONE volume or BEEP VOLUME all in the same manner. You can then turn the volume down for late evening operation. Menu 'B' is also easy to use but best of all, you have access to DCD sense and TNC control. At the click of a mouse. Try that during a contest when you need to change a value quickly. You can Even set a comment to display as a reminder next time you use the MEMORY CONTROL.

The 'Memory' settings are simple. Highlite the CH (channel) you desire and 'double click' on the choice. A smaller POP-UP will appear and you simply edit your frequency and other information that will support MAIN or SUB band operation. Yes, you can set tones for repeater operation as well. The rest is simple stuff.have the radio on and COM PORT communications running. Do your thing. You will enjoy the flexibility of the MEMORY CONTROL PROGRAM from Kenwood.
