Anyone have any experience with these tuners failing? The tuner powers up like it should but when RF is applied nothing happens. I think one or more of the RF sense diodes are bad? The unit was mounted inside my attic and I think RF got back into the tuner from the antenna. Anyway I have read...

Has anybody had problems with their YAESU FT-847 MEM / VFO CH rotary switch? Mine is kind of flakey, (and getting worse). It jumps around changing more that one channel at a time. I think this was a common problem? I don't know if a little contact cleaner would help or if it has to be replaced...

Hello all, I have a Tram D201A 40 Channel Base Station for sale. Cosmetically in excellent condition this sale will include the Tram D201A 40 Channel Base Station, Silver Eagle D104 mic, an extra handheld mic, two operators manuals, (one includes the full service section), a large, (35 X 24)...

I know someone is going to ask so...……….$375, but I'd rather not ship it. Its located in Myrtle Beach, SC. At that price I'll be taking a loss on it. I paid $475!

Thanks all for the input. The reason I primarily use the VFO is to keep the crystal selector use to an absolute bare minimum. It works OK right now! I'm not sure if I want to mess with this unit any more. I may list this "for sale" here. I haven't adjusted any of the cans.

I'm not sure what you mean by this.

I am beginning to think this is an alignment problem? The SSB RF is pretty good on channel 11-12 but then goes down on either side, sharply after channel 16. Also, why would the ALC circuit clip audio on one frequency and not another? I await the technical masters for comment...…………….

After further investigation the above quote is incorrect. The SSB RF output stays constant. It does not change as the unit heats up. It just varies over the channels as I have described.

Even more info: Around channels 12, 13, 14 where the SSB RF output is the highest, the mic gain acts as it should. When the mic gain is all the way up the power is the highest and the RF reduces smoothly as you turn it down. This is the case on the lower channels as well although the RF output...

Here a little more info. RF output on SSB changes as you go through the channels. Remember this is into a dummy load with a Byrd Wattmeter. Doesn't seem to matter what mic I use. Channel 1 is 5 watts, CH 5 is 6 watts, CH 10 is 9 watts, CH 12 is 10 watts, CH 14 is 12 watts, CH 15 is 5 watts, CH...

Hi guys, I'm new here on this forum and appreciate the comments. Anyway, here it goes. I have a Tram D201A that works great on AM, (at least 5 watts output and good receive), but on SSB the power drops from 12 watts (or more) to around 1 to 3 watts above channel 16. The radio has the VFO...
