I stand corrected on the frequency nomenclature. You would think I would remember that since I was a radio repairman in the Army in the late 60's. I went to school for that at Ft. Monmouth, NJ for 8 months straight. Anyone else out there from Viet Nam service, 1968-1969? I was at I Corp. Quy Nhon, An Khe, Pleiku, and Tuy Hoa.
