[Milsurplus] "ART-13" Variants

[WA5CAB at cs.com]

Ray,

ATC (later re-nomenclatured AN/ART-13) is to ATD sorta like AN/GRC-19 is to 
AN/GRC-14.  Competing designs by different contractors with the same intended 
function (multi-channel medium power MF/HF aircraft transmitter).  Receivers 
used with the ATD were the same mix as used with the ATC.  Which means not 
normally a BC-348, which was a Signal Corps set.

I threw in the weasel words "not normally" because just this week I had a 
request for connectors for an ATD.  Upon questioning the guy about whether he 
needed straight or right angle backshells, he gave me some of the details.  The 
aircraft, a B-25J, belongs to and is being restored by a CAF group up north 
somewhere.  When acquired, the aircraft was equipped (originally as far as they 
can tell) with an ATD and a BC-348!  I'm supposed to be getting more details.  
Like why they need connectors.
