I like using crystal control in some of my rigs and having a small band
where rock bound cw rigs can flourish will do wonders to get them on the
air. Vfos are also fine, but tuning + or - a few khz might be rewarding.

What a joy to fire up an old BA after grinding a crystal. We can grind
numerous crystals to the small window, to allow us to QSY.

Just restored an old crystal controlled Handbook rig, using a 6DQ6B.
