Includes the matching wickers modified power supply and interconnection cable. This item is serial: 11 dated these receivers were used in diversity set-ups and ran with the CV-31 ratty converters. Aesthetically, it needs some TLC.
The R-270 frr is a Hammarlund super pro BC-794 that has been updated by wickers engineering specifically for ratty signal corps. This belonged to my father and I an only assuming it works. Best guess from the experts seems to be only about 300 of these modified by wickers. Sold as-is.
