[Milsurplus] adding LSB to PRC 74A?

[Al Klase]

Mark,

I can't find my notes, so I'm working from memory.  The heart of the 
PRC-74 transceiver is a 1750 KHz LSB IF amp/filter.  The conversion 
scheme involved adding a modern crystal oscillator module at, say 1747 
KHz that moves the injection to the other side of the filter.  I think 
there was a miniature relay to switch between USB and LSB.  Of course 
you're left with a 3 KHz frequency error on the readout.

I think the only good answer is to get some Mil-HF-Pack activity going 
on 75 and 40 meters.

Regards,
Al
