[Milsurplus] ARC-5 look alike - APA-48

[Mike Hanz]

Employed two antennas and phase detection, using a crossed needle ILS 
indicator for a readout, Marty.  Intended for extended range detection 
of enemy aircraft with operating radar sets.  More details at 
http://aafradio.org/docs/APA-48.html - sorry about the serigraph aspect 
of the photos but it's a tenth generation copy.

Been off for a few days myself.
