3V SW-7 ReceiverSPECIFICATIONS
Frequency Range: 14 to 3000 metres (100 kHZ to 21.4 MHz)
Type: Regenerative receiver
Tubes: 3; types unknown at this time.
Power source: Batteries (6 VDC and 90 VDC) or battery eliminator.
Comment: 3V in the model number likely means 3 valve. SW-7 is likely the frequency range designator. Because the receiver lacks a bandswitch, it is believed that external plug-in coils determine the band of frequencies that can be received within the entire range.
If anyone can provide additional information, please contact: email@example.com
