terial.
The radio+TV broadcasts were in 1962, and I didn't have a TV.
nor did I, but the FM tuner that I'd built to a PW design could tune down
to Band 1 if I inserted an iron dust slug in one of the coils. It can't
have been a very good tuner since it managed the AM on Band 1.
Charles, do you remember which one that was at all, valve or
transistor?.
Valve. Using an ex-government IF strip.

Often wondered if it could have worked!, anyone know where the circuit
is at all? must have been around 1966 to 68 or even a bit later.
Mine must have been about 1958/9.
