Pearce Simpson, model Newport 120...... Schematics?
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!

Weren't those around 2 mc for the old marine frequencies? It might be a lot
easier tuning one to 160 meters than trying to get it up to 40 meters.

Yes, for sure! And some of these true boatanchors had MHz taps on the
coils (some call them inductors) switched with the channel selector switch.
I haven't had time (I'm retired, you see) to look inside yet. 160 meters has
so much local noise around here, in addition to needing more real estate for
antennas, that I'm thinking 40 is so much quieter, and half-wave antennas
will fit on my lot in any orientation.

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.

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.

That marine transmitter was made to connect to a short antenn. So 160
meters would be easy.

I also have a Pearce Simpson in my storage. Would also like a copy of
the Schematic.

OK, Bill, no promises for sure, but if any luck here, you are on the list!

I am looking for 1 of those pierce simpson cb tube radios. Anyone have 1
around?

look for "Pearce"
