GM2700 AM FM radio
« on: September 13, 2022, 10:56:19 AM »
I noticed that there is an antenna adjust screw above the tuner knob. Is there any instructions on how to adjust?

I read on another forum over the weekend that it apparently is for AM only. Stated to tune to a weak station around 1400 AM, adjust to get the best reception. Not sure if that is correct but I will try it soon.

Rapid Roy is right. It is an antenna trim screw. Tune to 1400 and adjust for best reception. It is to compensate for different length antenna masts. Only relevant to AM.
