[Milsurplus] ARC 65 control boxes

[Boeing377 via Milsurplus]

Always wondered why the only really versatile control box for the ARC 65 was found on the test set. This box allows direct dialing of frequency, no codes needed as on ARC 38.


I did see one of these test set control boxes on Pres Truman's DC 6 "Independence" (VC-118) at the USAF museum but thought it was a one-off unique install. 



The control box for planes had  20 channels, set by movable pins on a rotating drum. No way to directly dial up a new freq.


Well, I was wrong. Some of the "good" boxes were in USAF/ANG  planes.


Here is a pic from  KC 97L showing the test set control box mounted above the window at the NAV station.

The APN 70 LORAN set marks this as a late serving KC 97, probably late 60s early 70s. APN 9 preceded the APN 70.
