The 75S-1 receives SSB, CW or AM signals in all amateur bands between 3.4 and 30 mc.  The receiver coverage is in 14 bands, each 200 kc wide.  With crystals furnished, they cover the entire amateur bands of 80 meters, 40 meters, 20 meters, 15 meters, a 14.8 to 15.0 mc band including WWV, and the 28.5 to 28.7 mc portion of the 10 meter band.  The two remaining crystal sockets may be used for crystals selected to provide two additional 200 kc bands within the 10 meter band.  Other crystals may be substituted for those furnished to place the receiver at other frequencies throughout the range.

The receiver requires a 110 volt, 50-60 cps, a-c pwer source and consumes approximately 90 watts of power from the line.  It may be operated mobile from a d-c power supply by using the proper connector.  The 75S-1 should be connected to a speaker with 4-ohm voice coil.
