Hallicrafters SX-28

The Hallicrafters SX-28 "Super Skyrider" is an American shortwave communications receiver that was produced between 1940 and 1946 that saw wide use by amateur radio, government and military services.

The SX-28 included an Amplified AVC, a Lamb Noise Silencer, Calibrated bandspread, and Push-Pull audio output.

SX-28 and Hallicrafters S-27 and S-36 receivers were often rack mounted in British government listening posts and secret listening stations for monitoring German radar and communications during the war such as Beaumanor Hall in the English Midlands where German and Italian encrypted radio messages were sent to Bletchley Park for decoding.

[4] A number of the receivers were sent to the Soviet Union as a part of the Lend Lease Act, subsequently modified to accommodate Russian tubes.

The name "Skyrider" was intended to bestow an aura of exotic adventure to Hallicrafters products and had a long history with the company.
