  • Notes

  • The Gonset Commander II is a transmitter designed for mobile and fixed applications with an external power supply. Oscillator/ multiplier is a crystal controlled 6AG7. Final RF tube is a 6146 with power input of 35 to 60 watts depending upon final B+ voltage and mode of operation. Coverage is from 160 to 6 meters using plug-in coils. Two 7C5 loctal tubes provide for high-level AM plate-modulation. Designed by Faust Gonsett, famous for the Gonset Communicator series of VHF tranceivers, the Commander II uses the same philosophy of very compact design. The transmitter is very small compared to its power capability.  The set can be used with either a crystal or carbon microphone.

Transmitter power for older tube type units is typically expressed as input power.  Output is dependent on many factors including transmission type, amplifier class and efficiency, and frequency.  Power output and efficiency of a Class C transmitter such as the Gonset Commander II is about 2/3 of input power as a rule of thumb maximum.  The Commander, like most such transmitters if run at the highest power input  requires a separate B plus voltage for its oscillator, 300 volts in this case and often voltage controlled.  The final section can be run at either the same 300 or a higher voltage for maximum power input.
