Listening to history ....

With careful tuning I can listen to single sideband signals on my old Hallicrafters SX-25 receiver. The longer it is left on the more stable its internal oscillators become and it will "drift" less. When it drifts the frequency the radio is tuned to changes slowly requiring constant retuning ... just part of the charm of these old boat-anchors.

Listening to a single sideband signal on a vintage Hallicrafters radio receiver. The SX-25 was manufactured from 1940 to 1946 and uses all vacuum tubes with no solid state components.
