Thanks Nomad! I will see what I can come up with.

Hi Nomad, All the tubes are good. It will key up, but I get high input SWR and no power out. Stuart

Hi, I know I'm resurrecting an old thread, but I have a 600 that's doing basically the same thing. When I got it, the keying circuit was all messed up. All that is working now. It had the wrong tubes in it, so I put 36KD6's in it. It had 31JS6C in it. I've cleaned the contacts in the relay...

Howdy, My harder to find radios consist of an ARF 2001, Stoner Pro-40, CPI CP400 with the power supply and speaker and a well modified Buddy Base station. For the export crowd, I have a Cobra 148 GTL-DX, but its not functional. Stuart

There was one on ebay a month or so ago. I was really tempted, but decided not to buy it. I probably should have, but I have to many right now.. lol!

A while back, I picked up a 2547 that basically didn't work for $15. After replacing parts, I have it rx/tx on AM. It will tx on sideband, but no receive. It has upper and lower channels and a 10k switch. The limiter is cut, so I'll have to put that back in because sideband tx is muffled. I...

Hi Mike, Q55 which looks like the voltage regulator has 13.1V coming in and 6.86V on the center pin not transmitting and 6.62V transmitting. That should be 8V, shouldn't it? Thanks, Stuart

Good morning Mike, The 655 is AM/FM. Which transistor will this be? Thanks, Stuart

Howdy, A friend brought me a Stryker 655 that doesn't transmit. He was told it needed finals. He bought IRF520N finals for it. I 'checked it and it had no transmit or modulation, so I changed all 4 mosfets. So, It still doesn't transmit. I can turn the AM power down and get it to key up and...

Good morning, I just checked. The QT80 isn't eligible.

Thanks for the help! Next question… How much drive will this thing take? Not that I’m going to drive it that hard.. Tubes aren’t cheap! I’m just curious.. I tried it with a Grant LT and Galaxy 86V on am.. It doesn’t seem to swing very much.. I may not have it tuned right… It has a knob on the...

Hi Nomad, Thank you for the suggestion! I was wondering if one end would work or both. I will do both, hopefully this weekend. Does the wire size matter when grounding? 73

Howdy, Yes, its easy to work on. This one is the first I've really messed with. I've looked in a Varmint and a Swinger 105 and neither of those look very easy to work on...

Thanks Nomad! Without your board, it would have been a lot more difficult! I appreciate all the help all of you have given with this project. It was a great learning experience! I definitely like getting help when I have questions instead of being told to send it to a tech.. Thanks everyone!

Just an update on the POW… After replacing the 1000uf cap and the diode, I have 12v and the amp keys now.. I still have the 220uf caps to replace and to ground the coax, but this one is back alive! Thanks for all the advice!
