[ARC5] Airplane radios in jeeps

[Mike Hanz]

The box on the left is a control panel for the Bendix TA-6-* underneath 
it, probably a B model if the set was wired for 28v.  It was a 15w 
transmitter covering 2.8-12MHz with an internal dynamotor, and I would 
love to find one someday.  The control panel is not a well known Bendix 
product...at least it is not shown in any of the manuals I have here.  
The "official" one fit into a standard 3.5" four post aircraft 
instrument panel hole, and contained only a switch for off/channel 
1/channel 2, a toggle for CW/voice, and two jacks for mike and key.  
Bendix had a penchant for selling separate meters and control boxes for 
their transmitters, so it was normally a do-it-yourself operation for 
the military services to integrate them into a particular vehicle or 
aircraft, though this one looks like it is a well made factory product.  
Fabricating it required both an MT-33* RF current meter 
(http://aafradio.org/flightdeck/I-71A.html ), installed on the left hand 
side of this panel, and an MT-31* 300mA tuning meter 
(http://aafradio.org/flightdeck/bendix1.htm ), installed on the right 
side.   The MT-31 shown is probably one of the early ones, as it is the 
2.5" four post panel type (without the internal lighting of the MT-33).  
Bendix apparently found little market for them after the war began, the 
only exception being the SCR-269 (and earlier SCR variations) and 
AN/ARN-7 right hand zero "tune to max" internally lit meters.
