[MRCA] PRC-71/PRC-72

My PRC-72 is complete, and seems to be a more compact and lighter
implementation than the PRC-71.  I have not crystalled up the FM or VHF AM
set, but the UHF set works (has crystals for 6 freqs., including 243.0), and
the HF set works well.  I rebuilt the battery packs with new Nicad cells,
which the charger charges fine.  Mine also has a vehicular adapter and audio
interface.

Both the PRC-71 (Sylvania) and the PRC-72 (Bendix) were mid 60's attempts by
the Service to make a 4 band communication device (via 4 independent radios
strapped together or separated) to cover the 4 widely spaced bands needed by
an FAC (forward air controller). Bands were roughly 4-20 (2-12) MHZ SSB/CW,
30-50 FM, 110-140 AM, and 240-350 AM. 7 of the 8 radios developed were
channelized, while only the Bendix HF set was synthesized (2-12 MHz in 1 kHz
steps). Set was bulky and heavy. I do not think many were made.
