[R-390] What's the latest military manual discussing R-390A?

[Bill Kulze]

I went through Ground Radio school at Keesler Jan - June '77 and the first thing after basic electronics was Rx principles on the R-390. I don't think it was the 'A' as I seem to remember a squelch circuit. As a matter of fact, solid state was only the last couple days of the basic electronics part.
