[Milsurplus] Hammarlund Antenna - RC-281

[WA5CAB@cs.com]

David,

Ah hah.  When I went into the database yesterday, it showed the parent set 
for the BC-1269-A as SCR-615, which is a radar set.  As the database also 
included a long list of apparently appropriate components for the 615, I 
concluded it was correctly ID'd (although I don't have the TM's) and that the 
BC-1269-A entry was incorrect.  I have TM 11-260 which says in part "Radio 
Set SCR-616 consists of Antenna Equipment RC-281-( ), Radio Receiver 
BC-1269-( ) and Power Supply Unit RA-61-A.".

The RA-61-A is also used with several other monitoring (countermeasures) sets 
according to my database but I've only partially confirmed SCR-614 (VLF).

Hope that one of the PA/NJ bunch will pick up the antenna.  Incidentally, the 
BC-1269-( ) must have been specified early in the war as there were both 
BC-1269 and BC-1269-A's differing mainly in tube complement and 12.6 versus 
6.3 volt filament supply.  Later in the war, the first issue items tend to 
start out as the -A.

Turns out that both the BC-969-( ) and BC-1269-( ) were on my list of sets to 
get if and when.

Also, the TM 11-260 that I have (with C! & C2) is the 6/45 edition.  There 
was a later 1955 edition that I don't have.  Perhaps it shows R-593/GRR and 
the earlier one doesn't.
