Not much done today, replaced the valuable MVAM108 diodes by brute 1N4007 rectifier diodes. w/o any inductor, the tuning range is now down to 80Hz... now we are getting somewhere. I figure a capacitive trimmer could be used for "set QRG", maybe with a small inductor.
With the new crystal, frequency now reads 3.579793 on the lower edge and 3.579870 on the higher end.
Proposal: color burst qrss from 3.579790 to 3.579890.
