  • Pye C1 "Caddy"

    Portable broadcast having five transistors and two diodes, housed in a plastic cabinet in blue/grey or pink/grey; complete with white leather carrying case.

    Features: tuning range 525~1640 kC/s (kHz). Operates from five 1.5V Size C or recommended alternative manganese-alkaline batteries such as Eveready Type E93. Receiver will operate down to about 5V. Speaker: Rola 3CQ-00  audio output 300mW.

    Frequency response 100~6000 C/s (Hz). Controls recessed into top of cabinet include tuning, volume/on-off. (FROM MINGAY'S PRICE SERVICE)

    Converter, I.F., Audio pre-amp, series ("single-ended") push-pull output. One OA91 diode was used as a detector, and one OA91 diode was used in A.G.C. circuit by shunting loopstick tuned coil to reduce the gain as well as conventional bias control on I.F. amplifier. The converter runs with fixed bias.

    Includes a useful guide on setting up a test bench for measuring radio sensitivity in microvolts/metre.
