'Gibson Girl' Crystal Radio - UK Vintage Radio Repair and Restoration Discussion Forum

This series-tuned, shunt-fed crystal radio was built using parts salvaged from a vintage / battered SCR - 578 lifeboat radio (popularly referred to as 'Gibson Girl').

It consists of a baseplate, antenna tuning coil, antenna tuning capacitor and a terminal block modified to suit.

The only part required to be fished out from the junkbox was a Schottky diode SB 860.

The local 612 kHz, 200 kW AM broadcast station comes in real loud using a 60' long wire antenna and sound-powered phones. Headphone current, measured using a 1mA FSD 60 Ω meter, is 600 μA.

Regards,

Nandu.
