On my never-ending journey with this FT-101e... it's been working good for a while now thanks to Roger, G3YRO... but now what happens is when I transmit power output will be 0 for about 5-10 seconds and if I continue holding it in then the power comes back. It's not the relays as I cleaned them and they were cleaned a few months ago. It's not the carrier knob as I tried moving it around a lot and sometimes the transmit problem will try and go to where t needs to be and bounce back to 0 multiple times when this happens if I move the carrier it will "peak" at where it's resting. I tried cleaning the pins on the driver tube and rocking it, etc. and it's not that either. It's not band specific so we can rule out the trimmers on the bottom of the board. It's not Tune/CW/AM specific either. I tried rotating the mode and band switches many times while it's going on. My guess at this point would be a solder joint or component that is going bad in the HV cage that is exposed to the high temperature?
