The Cadillac of HF.

Hi OM,

I was teaching at TI 7 years later. By then we had both added and
retired the TED/RED (VHF/UHF) with the SRC-20-21, added the URC-17c
(RTTY), and topped it off with a "systems" class (for teaching patch
panels, tuners, and encryption) to lengthen out the curriculum. That
was called A4, you probable stopped at A3 (Radar had A5 and A6
sections that I schooled in before becoming an instructor in the Comm
division). The system lab was two identical ship's comm stations
HF/VHF/UHF in all modes. One side held a comm with the other through
dummy load leakage.
