As a kid the KWM-2 was "the" transciever to own. Of course I couldn't. Hell it wasn't even a consumer product like the Kenwood/Yaesu/Icom lines of today. It was Mil-Spec!
Though I did operate an S-Line in the Army a few times. I "volunteered" at the MARS station at Ft. Benning a few weekends. They were happy to have me, after they saw I could run traffic. The Mars Ops would take off for a few hours on Sat. and let the kid from the Infantry Scout Dog Handler school across the street run traffic.
When I came back to Ham Radio in the early 80's it was the Kenwood TS-830 I bought. Considered by many to have been the finest vacuum tube transceiver ever made. The perfect platform for a pair of 6146's.And then by the late 80's real hams moved on to the Kenwood TS-940 as the ultimate base station. They weren't perfect, but supremely fun to operate and actually took a basic understanding of RF concepts and electronics.
Looking back there is one thing these descendants of the KWM-1/KWM-2 shared. Even today the design of the 7600 has evolved from the Collins S-line in physical layout, center tune VFO knob, af gain placement, xmit tuning etc. The seductive allure of the emerging SDRs, not withstanding. I'll take these hard wired boxes every time.
