In these modes the DSP/SEL knob changes the frequency.
You're correct! Main tuning dial does not work in AM or FM - found it hidden on page 19 of the manual. The DSP/SEL does the tuning. But I found that can be changed in the menu.
Must be a reason for Yaesu to move the tuning to that little dial for AM and FM...
Operator was defective :-) not the xcvr...
Thanks for all the help!
