[Milsurplus] USN: ARB receiver used with GP-7 transmitter?

[W7QHO at aol.com]

John,

I have a GP-7 up and running off a 115vac, 800 cycle MG set from a TBW.  Agree, it would be a lot of work connecting up an external 60 cycle supply and probably not worth the trouble.  The GP-7 is rather drifty and FM's on phone; not too bad on 160 and 75 but not really useable on 40M.    Uses primary keying on CW and doesn't just chirp, it WHOOPS!  Primarily interesting as a curiosity.  I've never heard another one on the air.
