[MRCA] GRC-106 Remote at Gilbert?

[WA5CAB at cs.com]

It is still listed in SB 11-6 (FSC 6135 Primary Battery Supply Data) dated 
28 May 1982.  I don't have anything more recent.

But TM 11-5820-489-nn do not all date from 1983 through 1987.  The initial 
manual of the series, TM 11-5820-489-35P (which replaced SIG 7 & 8 AN/GRA-6) 
was dated 11 June, 1962.  TM 11-5038, which originally dates from 18 April, 
1951, wasn't replaced by a long-number version until some time after Change 
7 dated 16 May 1967.
