[ARC5] need advice on Tx tracking adjustment

[Robert Eleazer]

Many years ago I tried to mate an APR-4 tuning unit (IF 30 MHZ) with an ARR-52 (IF 26 MHZ).  Since the ARR-52 had a video output as well as audio I thought this would be a useful combination.

Anyway, I hoped I could just move the APR-4 dial by 4 MHZ, retune things, and be done. Nope!  I managed to pick up the local NOAA WX station but that was all, and I never got the tracking correct.  Even at that, it was a better combination than the APR-4 tuning unit and a Northrop Ventura UHF drone control receiver.
