With broken heart, I've probably thrown away 10 or 12 of these when I quit my marine electronics business. Now that I want to return to real Ham radio, and have no transmitter, I'd like to convert this old rig into an 80 and 40 meter cw rig. (just the transmitter) Should not be too big of a project, but having a real schematic (or one that's fairly close) would make memories return like magic! TIA, Old Chief Lynn, W7LTQ since 1948 If you obtain a schematic, I sure would like to get a file copy of it. I worked on lots of marine equipment in the mid 50s, but never a Pearce Simpson that I can recall. Worked mostly on Northern Radio and Apelco. In Ketchikan, AK, any boat owner who could afford it had a Northern, along with a Zenith Transoceanic and an S38C at home. Your conversion to 40 & 80 should be quite simple. Don 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. Old Chief Lynn, W7LTQ |
