Ham Radio - Kenwood TS-130S repair and cleanup.
Вставка
- Опубліковано 12 жов 2016
- A new ham in town purchased this radio from a neighbor that had it in his basement for 12+ years unused. It had a few issues and was generally a bit dusty and grimy. The new owner asked me to go over it and fix it up for him.
I always love the chance to get inside the older rigs. Follow along as I fix the old girl up and test her on the air.
This radio did not transmit on the WARC bands. Kenwood had locked them out when it was new, since the bands weren't official quite yet. There is a published mod in the user manual for enabling TX on 10, 18, and 24 Mhz. I make this mod on this radio. - Наука та технологія
You do an excellent job explaining everything in detail. I'm in the midst of a TS-130S that I got at the hamfest and your video showed me where to put back a connector that I took off.
These TS-130S rigs are known to have issues as they age and it is recommended to loosen then tighten snuggly every screw holding down each pcb inside. If you want to be really thorough you can put a dab of contact cleaner between the pcb and metal that in many cases it is to ground to.
One other suggestion: when setting your frequency, don't rely on the display completely. When you called that guy it was clear that you were 50 or more Hz off frequency by the Donald Duck sound of his voice. He might have come back to you on the first try if you had zero-beated on his voice. Many folks have a hard time getting call sign phonetics correctly when "Donald" calls, HI HI.
Keeo up the great work. 73!
Just picked up a TS-130s so thanks for the insight of the repairs I need to conduct!
Nice job. I learn something every time I watch.
Always like seeing these older radios placed back into service.

I absolutely love the AT130 tuner - It works great ! I actually bought a TS430, the power supply, and a speaker, just to get the AT130. It was a smokin deal. $250 for all of it about 2 years ago.
Excellent very informative for someone like me who is new to all this would have loved to have seen how you cleaned the components God Bless
Absolutely educational Kevin. Many people including me, have budgets that constrain us from purchasing new ham equipment. Your repair videos Kevin, give us hope that first off, the repairs are possible, and second, with some electronic fiddling backgrounds , these repairs can be done by the owner. Not always to be fair, however, if we match the faults to your repairs, a sudden light appears at the end the tunnel, so to speak. By the way, those long tubular light bulbs are common in aircraft emergency exit lights, they come prewired or bulbs separately. Anyhow, thanks for the awesome video. 73' KF2mS Biddeford Maine.
thank you Kevin. It makes sense but I never seen the display showing the shift in any of the radio I owned. Neither did I see it on this one. But maybe I just didn't noticed as I bought it only a few weeks ago and hardly have been using it.
That was agin a great video you did.
good job on the rig i was wa9eox in elmwood park il now in california 73 kg6mn that was a great rig
TS-130S and AT-130 tuner was the BEST and simplest transceiver I have owned. I even bought a spare AT-130 (also the BEST antenna tuner). I gave the radio and tuner to a trusted HAM friend, and it is still going strong (maybe "forever," who knows?) Hint: I cured the "drift" of the radio by simply exercising the crystal/vfo switch once in a while. Jim, AI4WC
A very nice r&r video, Kevin. These are always very rewarding especially since the radio is going to a new ham. Also there is a nice, comfortable quaintness about these "old" Kenwood and Icom rigs from that era. With a half-way decent antenna they are MORE than good enough to land QSOs for a skilled op (and really show how superfluous many of the bells and whistles on modern rigs really are).
I would only add that the burnt-out wheat grain bulbs JUST SCREAM to be replaced with the bright LEDs available with the shunt resistor. For example, I did an r&r on a DX-160 receiver and an old AN/URM-25D signal generator where the added brilliance was very welcome. Also consider the diode strips. They can be used with 12VDC and come with sticky tape to mske mounting easy.

Hi Bill. I would have done LED's had I had any on hand. I'm sure the bulbs will out-last his use of the radio.
He's been having a ball making contacts across the county and a couple DX so far.
+Kevin Loughin..understand. Excellent r&r job nonetheless. And, goodness, that radio must have been virginal when put into to storage not having the WARC mod done by the original op! Good job on the band switch work as well.
B3 interested in knowing your opinion of the 130S versus your IC-745.
72,
Bill, k6whp
Oh the 745 beats it hands down. Memory channels, selectable upper or lower sideband, continuously variable power output, switchable pre-amp, variable tuning speed, more sensitive receiver, passband tuning, and general coverage receiver.
I'm selling the 745 though. Another ham gifted me a Kenwood TS-440Sat that was dead. 9 hours of work and it's like new, so I'm keeping it.
Here I explain what happens with my Yaesu FT-450.
A few days ago I made the mistake of trying a radio from a friend of mine when my
FT-450 was on receiving, they had two different antennas but the separation
between the antennas on the roof are 3 meters. When I was testing the radio in transmission
I felt a burning smell from my friend and I realized that it was coming from my radio, at the moment
I turned it off and when I turned it back on it had changed many things like:
- TRANSMIT BUT DOES NOT GIVE ANY OUT POWER IN (AM) MODE ON ANY BAND.
- THE SYSTEM (ALC) DOESN'T WORK, NEVER MARK ANYTHING ON THE DISPLAY, BEFORE IT WORKED
VERY GOOD.
- ESPECIALLY IN 6M (50MHZ) BEFORE HAD 100 WATT, NOW ONLY HAS 10WATT AND WHEN
CW OR SSB TRANSFER FEELS MY VOICE OR NOISE IN THE RADIO HORN.
- THE INTERNAL RADIO TUNER ANTENNA DOES NOT ADJUST IN SOME BANDS AND HIGH SWR
WITH GHOST ANTENNA DUMMY 50OHM ADJUST 1: 1 ALMOST ALL BANDS, I REMOVED
THE RADIO TUNER ANTENNA AND CONTINUES WITH THE SAME PROBLEM, THE PROBLEM IS NOT
THE INT-TUNER OF THE FT-450.
- BEFORE ALMOST ALL BANDS DRAWN 100 WATT CW AND ALMOST 90 WATT SSB. NOW HIM
RESULT WITH LOAD DUMMY 50OHM PER BAND IS:
160m ...
fm .... 100 watt
cw .... 100 watt
am .... no carrier no power
fonia and digital .. 100 watt
-----------------------------
80m ...
fm .... 100 watt
cw .... 100 watt
am .... no carrier no power
fonia and dgital .. 100 watt
-----------------------
40m ....
fm .... 70 watt
cw .... 70 watt
am .... no carrier no power
fonia and digital ..40 watt
-----------------------
30m .......
fm .... 70 watt
cw .... 70 watt
am .... no carrier no power
-----------------------
20m .......
fm .... 70 watt
cw .... 70 watt
am .... no carrier no power
fonia and digital .. 40 watt
-----------------------
17m .......
fm .... 50 watt
cw .... 50 watt
am .... no carrier no power
fonia and digital .. 30 watt
------------------------
15 m ........
fm .... 80 watt
cw .... 80 watt
am .... no carrier no power
fonia and digital .. 80 watt
-------------------------
12m .........
fm .... 80 watt
cw .... 80 watt
am .... no carrier no power
fonia and digital .. 50 watt
When I transmit on the phone you can hear it on the radio horn
-------------------------
10m .........
fm .... 50 watt
cw .... 50 watt
am .... 10watt
fonia and digital .. 50 watt
---------------------------
6m .........
fm .... 20 watt
cw .... 20 watt
am .... 20 watt
fonia and digital .. 20 watt, When I transmit in fonia it is heard in the
radio horn. He also seems to be crazy, he makes noise and he seems to have serious
problems.
I RESET HOME OF THE RADIO AND CONTINUE WITH THE SAME PROBLEM, THE PARAMETERS
THE HIDDEN MENU IS CORRECT, THE RECEPTION IS CONSIDERED GOOD IN ALL
THE BANDS AND MODES.
I CHECK THE BOARDS OR BOARDS AND ALL ARE IN GOOD PHYSICAL CONDITION, NONE
COMPONENT SEEMS TO BE BURNED. BEFORE MAKING THE ERROR MY RADIO WAS WORKING
NO PROBLEM WITH 100 WATT IN ALL THE BANDS AND THE AUT INT ALSO WORKED
NO PROBLEM.
I HOPE THAT WITH THESE DATA YOU CAN GIVE ME AN IDEA OR OPINION OF WHAT PROBLEM
THE TEAM HAS THOUSAND THANKS IN ADVANCE.
note :Now I have realized that when I press the ATT or IPO key that is only for reception it falls
even more the power in all the bands, in addition I tested it in reception 6m 50mhz and it has problems
also at the reception .

So Kevin, I watch many of your videos, yesterday, 14 Jan,18.. I found a way to use a Soda Straw added to top of my mag lite, to help find solder pads on opposite side of the circuit board. Especially works well over transistors, the soda straw fits right over the transistor. When you turn the board over you can see the light over the transistor.
Excellent idea!
Found one in recycling yesterday.
I picked up a TS-140S on Ebay that was As-Is and didn't find anything wrong with it right away, it has electronic band switching instead of a troublesome rotary switch, but the meter lamp was pretty dim so I replaced it with a 1 Watt LED. The digital display went out when a little inverter module on the front panel board that produces a negative voltage died. I opened that up and found a bad zener diode inside it that I replaced and the two 7805 regulators were a bit low so I replaced them while I was inside the radio.
I just got this radio from my dad and plan to see about 30,17,12 meter lockout that you cut the brown wire on. The op manual says it will transmit on the bands , but then says diodes installed to prevent transmission. I guess once I get my antenna connected, I'll know for sure. Nice to see the insides without opening mine.
Nice work, 73's
awesome work. im looking into buying a kenwood Ts820s. and also a ts130s
Great job! Forgive me but I'm studying to get my tech. lic. I can buy a new radio but I like to know how to it really works and so I purchase a Kenwood TW-4000A on of all places,,,,,, eBay lol! I feel that if I learn the hard way going into it, I become better at understand more than just buy a new radio @ $300.00 plus, mainly my dream radio is YAESU FT-818 Thanks on your video it helps me a lot! 73's Wish me luck! Charles:) P.S. It has Optional Dual band CTCSS Tone Encoder. It is manual, Did homework on it found my local repeaters Tone #'s and now I starting to understand it better. I was in the dark before this on how it works. Now I know what to look for.
my first radio i had the 130se .. tnx jeff .. m0prf ..
Thanks Kevin for the video. After cleaning the wafer switches, do you use tuner grease or leave them dry?
I usually leave them dry. But I can see the value in using some kind of lubricant if you have it available.
I have a TS130S as well. After being on for about 20 minutes, the receive audio drops down to practically nothing and at the same time, the CW side tone gets louder than a car alarm; That's going to be a fun one to try and troubleshoot. It sounds like a cap in the AGC circuit might be bad but that wouldn't explain the side tone getting loud. If you have any ideas please let me know.
I just upgraded my Ham license from Technician to General and picked up a working Kenwood TS-430S with matching power supply, PS-430. The meter does not work on receive but does on transmit. Any ideas??? Can't wait to get a long wire antenna and antenna tuner to get on line. My radio has 2 mods, one white wire disconnected that allows all frequencies to be used and the 10th kHz jumper wire clipped to activate the last digit on the VFO. 73 from K9POW in eastern Tennessee.
I just purchased a ts130s with 30, 17 and 12 meters not activated..Do you have a video showing how to activate these bands?...Thanks, Tom
THANK YOU..I HAVE A 570G,,,ALC IS ALL THE WAY OVER BUT ONLY PUTTING OUT ONLY 50 WATTS..ADJUSTED INTERNAL MENU,DID NOT HELP.ANY IDEAS? 73
Can you maybe fix mine up? Working on my general and purchased this radio from an older Ham.
My model is the SE model. Curious what machine oil you use and contact cleaner. Thanks
I have a low sensitivity of about 1 mV and what needs to be replaced? greetings
I have a TS-130S. My daughter bought it for my Christmas present. The transmit power dropped to zero on several occasions. Have you had this problem? Could you recommend someone who could look at it? I live in Ohio in the Dayton area.
Sorry Jerry, I don't know of anyone out that way. You might pick up some contact cleaner and clean the wafers on the band selector switch. There are several. One section switches filters in the PA, I suspect you might have a problem there.
I tightened the screws on the circuit boards and the power came back.
I have a ts-130s just got every time I turfn it on I get a loud tone, like calibrator but not. HELP?
Kevin, I bought a used one and it works fine in SSB but in CW it shift the frequency up 600Hz as soon as I close the key. Any idea why? 73, Yvon NU6I
Shifts it on the display? In CW your transmitted frequency is normally offset by 600-800Hz. It has to be or the other station would hear nothing since you would be zero-beated. The VFO display shouldn't change though.
Kevin I’m thinking about to buy this model used… do you think is a good stuff? Thanks man
EA1IFS
Yes, it's a fine radio. Provided in good shape and tuned up.
I have one its just been repaired and sounds just like the one in the video M6goy
How do you kill the silly git making the plinky plonk noise
You are very innovative.

I need a tech for my Kenwood ts 130s & ts 530s my call sign is KB8WTA I'm good on Qrz
kevin there some bands that a tech can use that is hf
Yes, some of 10 meters, and CW portions of 80, 40, and 15. Did I imply otherwise? Sorry if I gave that impression.
hey kevin i would like to kno the 440s that you repair you did the removel of the glue do you think that u can remove the glue with heat gun or would not be good
I tried it, it didn't work. To get hot enough to soften the glue, I was heating the components way too much. I didn't want to bake capacitors that much. A chemist might know how to break that substance down, but then, you'd have it running around and making more of a mess.
I think the only way to do it is to be very patient and just chip away at it like I did.
ok i will let him know he going be giving me the 440s and i dont want it damage any more than it is
i told him to send it to me i got picks and other stuff to get glue out now he is going have replace one of the dioes but i am going to talk to him to night and hope that he see it my way becuse it works as far i know tx and recive
