|Geloso G 212-TR Transmissor|
The Transmitter G 212-TR has been designed to meet the requirements of amateur communications. Even with the limited power it supplies (60 watts imput to the final r.f. amplifier), this Transmitter permits secure and stable communications even under very adverse operating conditions. Its main features are: 1) Outstanding simplicity and rapidity of changing operating frequencies and bands. 2) Variable frequency Oscillator « Clapp » of high stability, and wide-band buffer and doubler circuits. 3) Plate-tuning adjustment of the final r.f. amplifier. 4) Pi-section Antenna coupling circuit, providing a means of matching different antenna impedances. 5) Rapid changing from « Phone » to « c.w. » operation, by means of a simple switching arrangement. 6) Modulator equipped with two 807s in push-pull, permitting undistorted 100% modulation, checked by means of a built- in measuring instrument. I t permits full utilization of the available r.f. power. 7) Audio frequency response of the modulator particulary adapted to voice transmission; this provides maximum intelligibility even under most adverse operating conditions. 8) Rapid changing from transmission to reception by manipulating a simple « Transmit-Receive » switch which simultaneously switches the Antenna connection as well as the plate supplies of Transmitter and Receiver. Both equipments start functioning instantaneously because the filaments of the tubes are kept warmed-up all the time. 9) Possibility of « zero-beating» the transmitting frequency to the opposite station’s frequency during reception by merely actuating a simple toggle switch which starts the r.f. oscillator/exciter. 10) Possibility of checking the plate voltage and the grid current of the final r.f. Amplifier tube as well as the modulation depth by means of a built-in measuring instrument. 11) Lay-out on a single chassis, enclosed in a sturdy metal cabinet of handsome and modern lines with gray hammertone finish to match the G 209-R Receiver.
