GM2700 AM FM Radio

I noticed that there is an antenna adjust screw above the tuner knob shaft. Is there any instructions on how to use the adjustment?

I haven't looked into these in detail but there are a couple GM radio service manuals you can download here http://67-72chevytrucks.com/vboard/s...d.php?t=545416

Re: GM2700 AM FM Radio

The typical procedure for adjusting the antenna trimmer on most Delco radios is to tune in a weak AM station (somewhere around 1500kHz if I remember correctly) and then adjust the screw for the strongest signal.
