The service manual for the Hallicrafters Super Skyrider Models S-17 and SX-17 provides detailed instructions on operating the 6-band, 13-tube superheterodyne receiver, including guidance on setting up the antenna, adjusting controls for optimal reception, and using the beat frequency oscillator for tuning weak signals. It also covers troubleshooting aspects such as adjusting the carrier level meter and managing audio gain to prevent signal overload, ensuring efficient operation across various frequency bands.
Manual Overview
The Hallicrafters Super Skyrider models S-17 and SX-17 are six-band, 13-tube superheterodyne receivers designed for a range of frequencies from 545 KC to 62.00 MC. Troubleshooting involves checking the alignment of the main dial and band spread dial, ensuring they are calibrated correctly, particularly when the band spread dial reads “0” for accuracy. Error diagnostics include monitoring the “Carrier Level” meter, which should read “0” when the AVC switch is on, the RF gain is wide open, and the receiver is detuned from any signal. Calibration adjustments can be made using the adjustment control on the back of the chassis. The board-level guidance highlights the use of separate coils for each band and iron-core transformers for the IF amplifier stages, resonating at 465 KC for improved gain and selectivity. The receiver’s tube lineup includes stages for RF amplification, detection, and audio amplification, with specific tubes like the 6J5 oscillator and 6V6 push-pull stage delivering significant audio power. The noise silencer, using a 6J5 tube, effectively limits interference, enhancing signal clarity.
Quick Issues Covered
- Diagnose power-up failures with RF gain and AF gain settings.
- Adjust carrier level meter with AVC switch in 'ON' position.
- Use schematics for circuit tracing and component verification.
Overview
The Super Skyrider models S-17 and SX-17 are 6-band, 13-tube superheterodyne receivers. They cover a frequency range from 545 KC to 62.00 MC, using separate coils for each band to maximize signal energy transfer. The manual includes operating instructions, antenna setup guidance, and details on the tube lineup and functionality.

Operation
The operation of the Super Skyrider models S-I7 and SX-I7 involves plugging the receiver into a power socket, typically operating on 60 cycle 110 volt alternating current. To turn on the receiver, the “Tone” control is turned to the right. During the warm-up period, the “RF Gain” and “AF Gain” knobs should also be turned to the right. The receiver is initially set to the highest frequency range, and the “Bands” switch should be adjusted until the pointer on the main dial indicates the desired band. It is recommended to start with Bands No. 1 and No. 2 before attempting higher frequencies. For distant or weak signals, the “BFO Injection” control should be used by turning the knob to the right, and once the signals are located, it should be turned off to avoid a continuous whistle. For C.W. transmissions, the control must remain on, and the BFO output strength is increased by advancing the control to the right. The “Pitch Control” knob helps adjust the beat note to a pleasing level. When the BFO control is on, the “AVC” switch should be in the “Off” position. For phone reception, the “AVC” switch should be in the “On” position, and the “RF Gain” control should be turned fully to the right. If the set blocks on strong signals, the sensitivity should be adjusted manually with the “RF Gain” control. The “Carrier Level” meter functions when the “AVC” switch is “On” and the “RF Gain” control is advanced to the right. For C.W. signal reception, the “AVC” switch should be “Off” and the “BFO Injection” control turned on, with variations in this control changing the beat oscillator output.
