[Milsurplus] AN/APR-4Y receiver MF wanted

[WA5CAB at cs.com]

Ed,

The two AN/APR-4 receivers run off of 115 VAC 60-1000 cps.  The APR-4Y only 
runs off of 400-1000 cps.

Besides the nomenclature, the difference between the AN/APR-1 plug-in's and 
the single-band ones for the APR-4(*) is that the former do not have the 
scann motor and limit switches.
