[ARC5] ARC-39

[D C _Mac_ Macdonald]

With a pair of 28V 6146s (maybe modulators instead of RF amps) it should be able to give you 75 and 40 meters with a fairly respectable signal all in one box!  I'd also like to have one!

I believe the early B-52s HF may have been ARC-21s (AM) that were replaced by ARC-65s (SSB) which were what were in the B-52F models I flew in back in 63-66.

73 de Mac, K2GKK/5
Since 30 Nov 1953
Oklahoma City, OK
USAF, Retired ('61-'81)
FAA, Retired ('94-'10)

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!!!
