[Milsurplus] ARC-4

[Brenda Gentry]

The ARC-4 was based on a commercial rig developed by Western Electric 
before the war. They had a journal called "The Oscillator", and one 
issue had an article about their work on VHF aircraft radio entitled 
"Aviation clears it's Voice" if I recall right. I will look to see if I 
still have the journal.
