[Milsurplus] [ARC5] [MRCA] AN/PRC-74 Schematics

Tue Dec 4 09:37:00 EST 2012

To bad that LOGSA is not more open to the public.  I understand the need to keep the modern comsec stuff under wraps, but to reclassify the Vietnam stuff after 9/11 and even some Korean war radios was a bit over the top.  A lot of the VRC-12 material is not available anymore nor some PRC manuals.  Wonder where some of that has gone?  It was digital so should still be somewhere.  Anyone still in the military that knows?  Also how about our international friends, do you have a spot to download from or do you have the same problem?
