I have the operator manual for the AN/ARN-11.  There's no official JAN designations of individual components, just commercial model numbers.  The Bendix RTA-1B HF receiver-transmitter is the same way.  I have both commercial and military manuals for this unit, and I have the RT unit.  It was officially known as the AN/ARC-9, yet only commercial model numbers are used in the military manual.  Only red paint SC stamps (but no AN/ARC-9 marking) and the frequencies of the ten crystal-controlled channels shows the RT unit as a military AN/ARC-9.

The Setchell-Carlson range receivers are another story.  I have two Model 512 12v receivers, one marked "R-76/ARR-13" with a red paint stamp and the other not marked at all.  But the unmarked one came with a manual for the AN/ARR-13.  Both had the common red SC stamps on them.  The oddball Model 591 range receiver was apparently officially known as the "AN/CRR-1" but who knows why?

Then, you have the BC-348 receivers which became officially known as the AN/ARR-11.  You got to love these naming systems.  I'll bet that, just like the MN-28LB and the RTA-1B, no BC-348 ever actually bore a JAN marking.

I've always wondered why they didn't confer some official military nomenclature on the AVT-112/AVR-20/AVA-126 gear.
