[Milsurplus] Collins 0-492/FRC-44

[WA5CAB at cs.com]

Well, now I'm puzzled.  But first off, it obviously isn't test equipment.  
The parent set is AN/FRC-44.  However, my previous information was that 
AN/FRC-44 was an HF RATT and SSB set built around RT-671/PRC-47.  And I have one 
PU-385(WX-1)/FRC-44 that supported that hypothesis.  PU-385 is a rotary inverter, 
115/60 in, 115/400 out, which will run the RT-671.  And the way in which the 
inverter is constructed is very similar to what the photos of the O-492 and two 
other /FRC-44 items that the seller has listed show.  But I don't know why 
there would be any need for a seperate reference oscillator and divider string.  
Unfortunately, I don't have a manual.

I agree that it would have been better had the seller just listed 
O-392/FRC-44 for sale as a unit.
