Re: FT-101Z Tuning Issue
Try exercising the switch, end to end, 20 times. If that helps give it 20 more. I find that any radio that has not been used regularly can benefit by exercising the switches. It wipes any oxide off

Re: FT-101Z Tuning Issue
I agree with the below
Until you can solve the meter issue you could try:
At plate dip, power out should be max – measured on external power/swr meter - provided the final tubes are aligned

FT-101ZD changing the 2.3KHz SSB filter for a 2.7KHz filter?
Would changing the SSB filter to a 2.7KHz filter improve RX audio quality on SSB / AM?
Sadly the 101ZD has no switchable filter for AM / SSB and I've got a spare 2.7KHz Yaesu filter 'flying'

I had an FT-101B that had been in storage for over 20 years and fired it up. At first it worked and then didn’t. I found that there were two small diodes in the power supply that had died,

Thanks for the input, I can't find the elusive FH2 by tracing, using magnifying glasses, bright lights, mirrors, etc so I'm done with it. It's now listed for sale on QTH.com.

Re: FT-101E Signal Generator is off frequency
OK. Does your radio have the WWV receive crystal installed?
If yes, tune the receiver to it and zero beat the carrier while listening
with headphones.
Then off tune a bit so you hear a 400hz to 800hz

Thanks Bruce. Something is off somewhere, I'm just not sure where. I know that if I pull up the 14.300MHz Maritime Mobile net, I can center the VFO dial on 14.300 and hear the net fine, so I feel
