Rick, it sounds like the PTO is no longer tracking as it should. These are very old radios and that is often a problem. There is an adjustment but you will have to remove the PTO to do the adjustment. Often the adjustment cannot adjust the total offset since these radios are so old. If you can calibrate the unit at all frequencies then just live with it.
You could take the PTO out and send it to Howard Mills W3HM. He does these every day. But keep in mind that it may work or may only get part of the way. You could ship the entire radio to Howard as well. He does great restorations of these radios.

Before I dive into this R-388 head first I better find out if there is a problem or it's just an idiosyncrasy of the receiver. On all band settings, .5kc thru 30mc, the dial is very close to center turning the "Calibrate" only a little. However, when I move to the right of center the calibration gets worse to he high side and the opposite happens when I go left of center. It is more than just a tad. If I go close to the edge of the dial (especially the high side) I am no longer able to move the "Calibrate" enough to line it up with the dial. The receiver seems to be very sharp, hears great, everything functions properly and in general has no problems. Since this is my first 388 I didn't know if this behavior is normal or if I have a problem I need to correct. The dial and tuning mechanism seem to have very little if any slack and move very smoothly. There is a little bump on each revolution I am guessing is normal. I hope I have described this right. Any ideas or advice? Thanks, Rick/K5IZ ______________________________________________________________ AMRadio mailing list Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] AMfone Website: http://www.amfone.net AM List Admin: Brian Sherrod/w5ami, Paul Courson/wa3vjb
