Probably the first panoramic adapter on the market. An article describing the technology can be found in Radio magazine, Mar 1942, several months before Hallicrafters announced the S-35. The Radio magazine article appears to be the first reference to the technique of panoramic reception.
Provides a visual presentation of band activity up to 100 kHz wide. Rack mountable. The S-35 is virtually always shown with the SX-28, but the two units were sold separately, and the S-35 will work with any receiver with an IF of 455 kHz.
Power: 120 VAC
