I clearly remember dad (W0QOA) who is SK now and I setting at the kitchen table
in the early 60's and grinding crystals to move the frequency to the novice
band. Seems like dad used a fine powder substance that was abrasive. It
worked and we moved several and ruined very few. Of course everything he had
was modified in some way. I still have and use some of those crystals with my
DX 20.
Does anyone have diagram or literature on Autek MK-1 memory keyer. I need to
fix it to use with my Drake C line. Be glad to pay for a copy.
