The Servo Corporation R5200 is a tube type VHF recceiver covering
50-200 Mcs i n one continuous band. A Mallory spiral "Inductuner" front
end provides significant bandspread while allowing continuous tuning without band
switching. AM, wide FM and CW modes are selectable. Squelch is provided. I had
two of these at different times. The first when I was a teen - which I used to
listen to FM broadcast as well as to scout around the VHF bands. This was a pretty
good quality receiver for its time. I would like to obtain another someday.
