Check the antenna leads.  Both the R-26 and the ARB are wired to the ATB.
Therefore, since the ATB has an internal antenna relay, the R-26 antenna is
not switched by the ATC, but by the Command Set.
This leads to some interesting speculation.
3 MC and 4 MC frequencies were primary operational
and ASR, as we've documented in other threads of late.
I think it likely that, in this installation, the R-26
acted as a second Command receiver, probably guarding
either the ASR frequency as required or some other
primary frequency.  I can't find the hi-rez scans
around here at the moment.  To what frequency
is the R-26 tuned?  Can't quite make it out.
The R-23 tuning goes to the pilot, of course,
not the radio op.

An aside:
In the second photo- the one of the Radio Op's desk.
What is that thing with the insulators that would be
beside his left leg,
the thing to the right of the fixed/trailing knife switch?
