My first taste in marine radios was as a helper in 1948, getting purse
seiners ready to head for Ketchkan. There was a lot of converted "war
surplus"..... The only one that sticks in my mind was a BC-375 transmitter
converted to crystal control. Remember that one? I had one still operating
as MOPA, using a bunch of old junk car batteries for power. Boy, did it have
a distinctive yooop did dee yoop! Good for a half hour CW on 40 meters
before charging batteries for another day.
Second chance in marine radio was a 20 year stint beginning in 1977.
Northern Marine 550's were king of the North Pacific (if a good man did his
work with the tuner, antenna and ground system! Bet you had a good time with
those too!
If I come up with the schematic, I'll pass it on Don.
