Ad Message: | For Sale is a Collins 242F-9C transmitter that has been converted into a 2 meter linear amplifier. The transmitters had a solid state exciter that were modulated at the last stage. The modulated signal was then amplified by two stages of linear amplifier, a 6816 tetrode operating in class "A" driving a 4CX250B tetrode operating in class "AB1". The transmitter was so reliable that many of the were shifted into "Omni" service. This unit has had the exciter, modulator and associated metering circuits removed and a +12 VDC PTT circuit installed. An input signal of 100 milliwatts produces an RF output signal of 250 watts. It has been operated regularly at 300 watts out. I can not ship this unit, it must be picked up in Genoa, NV. More spare tubes are available. Complete with a spare set of tubes and manual. $250 |
