Sometimes called the GSB-II.
The Gonset Sidewinder SSB, CW, and AM transceiver covered the 2 meter band in four 1 MHz segments. The receiver was completely transistorized. Input power was 20 watts on CW and SSB, 6 watts on AM. The accessory power supply snapped on the back of the transceiver or could be mounted remotely.
Specifications
– Frequency Range: 144 to 148 MHz.
– Frequency Control: High-frequency conversion is crystal controlled.
– Frequency Stability: After a 15-minute warm-up, ambient drift is -50 cycles per 15-minute period (under ambient conditions with transmit filaments on causing chassis heat rise). The temperature coefficient is 300 cycles for a 10° change.
– Final Stage: Uses a link-coupled final amplifier.
– Emission Modes: Supports AM, SSB, and CW.
– Power Input to Final Amplifier: 20 Watts PEP on SSB, and 6 Watts on AM.
– Spurious Suppression: Rated at -50 db.
– Unwanted Sideband Suppression: 40 db on SSB.
– Carrier Suppression: Rated at -50 db.
– Audio Response: Covers 300 to 3000 cycles.
– Output Impedance: 50 ohms.
– Sensitivity: 0.5 microvolts for a 10 db signal-plus-noise to noise ratio.
– Intermediate Frequencies (IF): Dual conversion with a 15 MHz first IF and a 9 MHz second IF.
– Spurious Rejection: Rated at -50 db.
– Image Rejection: Rated at -50 db.
– Audio Output: Delivers 3 watts into a 4-ohm load.
– Antenna Input Impedance: 50 ohms unbalanced.
Transmitter Tube Complement:
– 6EA8 Transmit Mixer
– 12BY7 RF Driver:
– 6360 Final Power Amplifier
Power Requirements: 12.6 VDC, 100 watts, 80 amps maximum
117 VAC depending on the connected power supply.
