Anyone got any clues as to whyit's dead? The previous owner said it was working then it quit.

FT-ONE@groups.io | PLL Local Oscillator (54.28 MHz) not working

groups.io

"One last thing you might try is to tweak T21 and see whether the oscillator springs into life, but I would recommend you only do this (a) with a proper plastic adjustment tool and (b) only if you think someone may have been playing with it.
- This oscillator is pretty important, I would think the FT-One would neither transmit nor receive without it."

Might be some place to start

Want another one? Got one that reported receive but no transmit 30 years ago. Couldn't find a source of the discontinued TI-made mixer chip in the transmit and it's been in a corner ever since. No way I'll ever make it work, but it has to go.

Somewhere.

Probably not as shipping will be crazy high. I'll probably end up dumping this one in the trash . I can't get it to do anything..

Just like all other vintage radio gear, one of my kits usually brings them back to life. Hopefully. See link below;

Yes I know as I'm in the process of doing a recap.

Great! Once you are done that project, troubleshooting, if needed, will be more productive. Good luck with your re-cap.

I ended up guvig up. Tbe boards are modular and double sided and its just too much of a job. I'll just either sell it or junk the thing
