>Mike, those PB4Y-2 photos are very interesting.  In the first, there is an ARB/ATB installed, and two AN/ARC-5 receivers installed, both of which appear to have the MX-20 adapter.  I say it's AN/ARC-5 and not ARA, because the receiver to the right has loop antenna posts.

Agree, though the adapter in the R-23 appears to be the MX-19, not the 
MX-20 adapter in the R-26 receiver to its left, since it lacks the plate 
to the right of the connector.  I should have looked more closely before 
labeling the receiver as an ARA, but my bride had called me to dinner.  
Priorities must be observed...   :-)   Obviously the techs slapped in 
whatever made sense to them at the moment, since the MX-20 in an R-26 is 
a sorta strange animal.

>I'm surprised to see the LM figure so prominently with the ATC/RAX-1.  The internal CFI of the ATC should have allowed frequency setting of the ATC and the RAX-1 to sufficient accuracy without any external CFI.  Maybe it was actually used for the nearby ARB/ATB.

Well, this is a Privateer which was devoted to ELINT work, so precise 
frequency recording was a requirement...
