Doug,
? ?The V6 is similar enough to the 5 that??will still apply. The PCB is different, I think the audio amp was tweaked, and the crystal filter shifted a slight amount to resolve some spurs (I forget - did that happen from 4-5 or 5-6?).
? ?Most of the questions/topics you listed apply through the line from V3 on, so the massive volume of 'corporate' or 'tribal' knowledge here applies directly to our V6s.
? ?Anyway...FWIW
