Ideas for an old Kenwood TS-120V 

Thanks. Hopefully, I'll be able to track down all the faults.

Hi Dave, Change of plans! See above.

@@CharlieMorrisZL2CTM Good on you Charlie a real kind thing your doing.

It's the least can do Dave. I'm in a lucky position that I can just buy stuff to play around with. I wonder if I should put out a video series? It would again be the world according to me (right or wrong)!

Hi Devin. Let me think about how best to address that. I'll endeavour to include more in the videos.

Very nice. I must admit I enjoy mine. Nice and simple.

Thanks for the steer Ed. I'll jot that down.

That's a really good point Greg. You know I might-will do the same. While I don't know of any around here, I'm sure they are out there. I'll fix it up and reach out to the local ham club. Thanks again for the steer.

@@CharlieMorrisZL2CTM Put me down for one, please

Agreed. As you can see above I've changed my mind. I'll fix it up and give it someone more needy than me.

I will Dave. I'm going to update the show notes to reflect what I will do with the radio. That's a much much more worthy cause.

Another thing , relay contacts can be source of intermittent problems. Nice work on your new tramping radio. Winter has been mild here in south western Ontario Canada. Come on spring. 73

Sure thing Neil. For now it's a half wave dipole using twin-flex cable. The cable come into the shack and into a tuner (via the balanced wire output).

Will do. They are a great little rig. Nice and simple.

Hi Aleksander. I see the radio does have the ability to have a narrow bandwidth CW filter installed. Without it, you have to use the wider the SSB filter, which will make it harder to tune into closely spaced CW signals.

Hi Clive. Thanks for the feedback. I'm glad you find the videos useful.

Are you up to help troubleshoot a TS-120S? I got one recently, and it looks like it's been dropped down a flight of stairs.

Thanks Colin. I may have to call on you as I fix this up.

Thanks Paul. I'm still looking for another doner. As pulling it apart, for me that's part of the enjoyment. Either get the old hardware to work or graft something else in. All good fun.

I really like the simplicity of the radio Rafat.

Thanks John. Slight change of plans. I might have to look around for a more suitable doner for the original idea.

@@CharlieMorrisZL2CTM Understand that. Older Kenwoods at least, they seem to like take a chassis, solder a board in the middle of it then start soldering other boards to it and building it around it. Making it impossible to service the darn thing. It would be cool to have the band pass filters on that big open wafer switch but you are probably right. Splitting it up not be easy. If anything be sure to check the P.A. parts and such to keep for spares. P.S. I have actually followed some of your ideas with bandscope on my Kenwood ts-940s. IF port though, it no work and never knew it, I mean I get nothing even with the preamp turned on the spectrum analyzer. Next Digikey order get some good op amps and make a buffer circuit for other radios. I mad at the Kenwood right now. LOL. 73's and I am watching.

@@CharlieMorrisZL2CTM quick note here. Looking for a site to post pics to with easy access to show my projects. Not much a video person, yet. Got lots of things I have done. And call here is KD9JWZ in Indiana.

@@johncundiss9098 John. You may wish to look at Blogger dot com. It seems to be nice and easy to update.

@@johncundiss9098 Sounds like you are having fun. Good stuff!

I'm sorry Greg. I'm not sure. If you have test equipment, try diving the circuit in half and looking at the signal before the crystal filter. That way you should be able to narrow down where the problem may be.

​@@CharlieMorrisZL2CTM yes, I will, thanks

I will do one of these at some stage. I'll have to look for a more suitable doner.

Theres a TS-120S manual there - I don't know what the diff is between that and the 120V

Thanks Christina. I'll take a look.

one is 100watts and the 120v is 10watts

Hi Bernd. If you could email it to me then that would be great thanks. I have a couple of 120V copies here, but the scan resolution is not too good. Thanks again.

@@CharlieMorrisZL2CTM Had trouble sending it via email. Let me know if something has arrived to your mail address. On the other hand, I will send the files individually.

Will do.

Hi @Bernd B. , I’m trying to fix one of them. It was showing dots on the display.pll not locking. I have fix it but now I have low receive level. can you help me please? maybe you know already where to look at. thank you in advance .

@@michelebergo91 In many cases it is the band switch which switches the individual input filters. The built-in relays (antenna switching) often have contact problems due to their age.
