Tip- the antenna trim has a rotating cam which operates a micro switch to peak on different bands. I had to nudge the switch slightly as the cam was not pushing the switch fully when rotated so peaking did not work! 73 G4BTI.
I just enjoyed your nice and clear explanation of how the radio works and how to tune it properly it was fun because I have one like that myself.tkanks very much
What about the external jack ,is it for an external dc current supply ? Do you know if the chassis is on the plus or minus of the battery?thanks for the nice video and the precious detailed information on how to operate it.
