Yaesu FL-50 Transmitter
The Yaesu FL-50 used Yaesu's 5 Mhz crystal Filter, was crystal controlled (with a VXO [variable crystal oscillator]), had a built-in AC power supply and was of single conversion design. It was all valve in construction, but had a matching solid state VFO, the FV-50B (a later version of the FV-50 with the addition of an RFA [Receiver frequency Adjust] control), which allowed freedom from the restrictions of crystal control.
In looks it closely matched Yaesu's FL-50 and FR-50 valve transmitter and receiver of late 1966. The model DC-50 mobile power supply was available to allow 12 volt DC operation of the FL-50 using its in-built AC mains power transformer..
The top photo, showing both the FV-50B and FL-50, was taken in February 1968 by Victorian photographer Alan Elliott for Bail Electronic Services.
