[Milsurplus] [MMRCG] The Navy MAK so far

[arc5 at ix.netcom.com]

------ Original message------From: Ray Fantin...Anything that can give me 190 to 250 VDC in receive and 350 to 500 VDC along with 10 to 20 volts of Bias in transmit. Remember that it has to work from twelve volts because this radio is for field operation only.----Ray, look for an old tube HF mobile supply like the Drake DC-3.  The Australian set here is run with a Hallicrafters FPM-300 mobile supply and an outboard regulator for the +220V (utterly eliminated CW chirp and Rcvr drift).  Also has a bias supply.  Tweaking that to get the value you need should be easy.
