Re: Yaesu Ft-301
If the vox is not working, you can verify the ic mc14011. It's a trouble source. PP6EW Emerson Em qui., 23 de dez. de 2021 ¨¤s 03:29, <vorsterjanco@...> escreveu:

Re: Low power output on 80 meters.
I would first check DRIVER output just disconnect the PWR AMP input BNCs on the back. If driver making 5-10 watts out, then problem is PWR AMP LPF or band SW wafer switches.

Hi again, I'd pretty much finished restoring my FT-301 analog rig, but have noticed that the dial has three spots in every revolution where it catches just a bit. Right around 14, 47 and 80 kHz

Re: Removing FT-301 VFO mechanism ?
I had a similar binding problem on my FT-221. It turned out the central shaft in the vernier drive was slightly bent. I convinced it back into straightness with a lathe, a maple dowel and a bit of

Hi Jon, Well I must commend you on your determination, working on that radio in a hotel room! Lucky that you had access to a lathe. I don't know anyone who has one, but perhaps I can find a way to

Re: Removing FT-301 VFO mechanism ?
I travel for work for months at a time. Bringing projects with me saves my sanity! Make sure to have a plastic bin handy to catch the tiny balls in the vernier as you disassemble and clean. They can

Re: Removing FT-301 VFO mechanism ?
I've disassembled the VFO mechanism sufficiently that I know the culprit. I just don't know what to call it, as there's no mechanical drawing in the manual, or list of VFO mechanical parts that I can

Re: Removing FT-301 VFO mechanism ?
Well darn, that shaft was NOT bent. But still several points in rotation of the shaft where it "sticks" momentarily. Perhaps some fresh grease might help? Anybody have a suggestion for a good grease
