I think you hit the nail on the head.  Makes perfect sense.

Re-thinking my earlier post, it appears obvious now that the ARC-39 replaced the ARC-2 for reasons other than progression of nomenclature.  It was in the early 50's that aircraft radios used in both MIL and civil operations needed to comply with the newer RTCA standards.  Radios like the ART-13 with the Comco crystal modification and the intro of radios such as the Bendix RT-series HF, the Collins 18S-4, and thence to the ARC-38, etc.  The old VFO transmitters simply could not provide the required accuracy and stability.  So, its entirely possible/probable that the ARC-39 replaced the ARC-2, illuminated by the fact that the airframes they were installed in were the same.  I'd like to see/have an ARC-39.  Something new!!!
