Snap on clips are provided for connection to dry cell batteries for high voltage, and a single D-cell battery holder is provided for the filament supply. Switching from transmit to receive applies filament power to only the half of the tube which is in operation. The receiver is a regenerative type. Regeneration is controlled by a potentiometer across the feedback winding of the tuning coil. Frequency coverage is claimed to be 3400 kc to 8000 kc in the manual, however dial calibration does not go below 3500 kc.
Audio output is intended to be fed to high impedance headphones.
An optional stage of audio amplification using a type 3V4 tube can be added for operation of a small speaker. A pre-punched hole in the chassis can be utilized for the purpose of mounting the additional tube. The unit in my collection was purchased in August of 1989, from Antique Electronic Supply. It was featured in a sale flyer that was sent out, and I don't believe it was ever offered in regular catalogs. I suspect that their inventory of Western Radio items has long since been exhausted.
