Controls & Indicators
The front-panel controls and indicators for the SKYRIDER MARINE Model S22R include:
1. Tone Control: Turning this control to the right connects power to the receiver, indicated by the dial light behind the translucent dials.
2. Band Switch: Used to select the desired frequency band for standard broadcast coverage.
3. RF Gain Control: Adjusts the sensitivity of the receiver.
4. AF Gain Control: Adjusts the volume of both the loudspeaker and headphone circuits.
5. AVC Switch: When ON, it allows automatic volume control; when OFF, sensitivity must be manually controlled.
6. BFO Switch: Activates the beat frequency oscillator when turned ON.
7. Pitch Control: Adjusts the pitch of the beat note to a pleasing level.
8. Send Receive Switch: In the SEND position, it removes plate voltage from the tubes, making the receiver inoperative during transmission or standby periods.
Installation / Setup
The installation highlights for the SKYRIDER MARINE Model S22R include examining the carton and receiver for any transit damage upon receipt, and filing a claim with the carrier if damage is apparent. The receiver operates on 110/125 volts AC-DC, and an external converter is required for operation from a lower voltage DC source. The cabinet dimensions are Length 184″, Depth 10″, and Height 84″, and it can be placed in any location convenient to its power source and antenna. The chassis is at the same ground potential as the cabinet, reducing the risk of a short. An antenna should be connected to the A terminal, and the longest possible wire is recommended for optimal reception. For a commercially available “all wave” doublet antenna, the two-wire transmission line should be connected to terminals A and A1, with the jumper removed from A1 and G.
Operation
After connecting an aerial to the receiver, plug the power cord into the power socket. Turn the control marked “Tone” to the right to connect power to the receiver, indicated by the dial light. Allow a few moments for the tubes to reach operating temperature. Place the band switch in position #2 for standard broadcast coverage. The frequency range by bands is:
Band 1: 110 Ke to 410 Ke
Band 2: 400 Ke to 1500 Ke
Band 3: 1.7 Me to 5.9 Me
Band 4: 5.3 Me to 18 Me
Adjust the sensitivity with the “RF Gain” control and the volume with the “AF Gain” control. For telephone signals, keep the AVC switch ON and adjust the RF Gain for maximum sensitivity. Adjust the volume with the AF Gain control. With the AVC switch OFF, manually control sensitivity with the RF Gain control. The BFO switch activates the beat frequency oscillator, and the “Pitch Control” adjusts the beat note pitch. The “Send Receive” switch in the SEND position makes the receiver inoperative during transmission.
