R-1490/GRR-17
USMC RADIO RECEIVER
A neighbor (non-ham and non-radio enthusiast) has two of
these units that he got some years back. Both are in pretty nice physical
condition but not operational.
Radio #1 (S/N A160, case A88):
Radio #2 (S/N A296,):
Note only one set has the AC cord
while both have the DC cord. Neither radio is working though one has audio but
no RF through.
