[Milsurplus] AN/GRC-27

[Bob Wilder]

An interesting story about the Jerk 27 thought the list might like.  While stationed at the
Fortuna AF  Station GATR site we used to use a GRC-27 to drive the spare channel of the
FRT-49 data link transmitter.  As the FRT-49 runs about 22KW it sure would overcome most
of the ECM used by SAC on exercises.  Everything was all OK until the Navy started to 
complain that we were wiping out the bombing range communications off the Washington State
coast.  We never realized that UHF would carry about 1200 mile ground wave. But think
about it, 22KW at 290Mc into a high gain slot antenna and an ERP close to a megawatt.
