Re: Yaesu FT-107M HF Transceiver. Help required please.
This is a symptom of the VFO not oscillating, I experienced similar with my old FT101ZD. Probably as said a dry joint or (more likely) dodgy switch contact, but make sure you have got the switches in the right position - and especially have not selected one of the external VFO options which will do this if you don't have an external VFO fitted.
