I am looking for a AF/RF gain control, which includes the on/off switch
for my TR-7.
Also, the TR-7 is getting lazy about switching back to receive from transmit
on both CW and SSB. I suspect the T/R relay because I can repeatedly
switch back and forth and it will eventually receive properly. Is cleaning
and/or burnishing the contacts on these typically enough to solve this
problem, or does this usually require replacement?
Email address on QRZ is good if you wish to reply that way.
