It's frequency can be adjusted by a single tuning knob which controls a BB112 tuning diode. Also you can connect a microphone preamplifier if you want to transmit your voice. It operates on 15-16 Volts DC (DC power supply operated) (power supply not included). Two 150W 100V RF power mosfets are used at the output section to withstand high VSWR levels due to random type mismatched antennas.
Tunable on any desired frequency within it's coverage. IRF540 power mosfets as PA stage. 2N3904 transistor as RF driver. 2N3904 AF power transistor as modulator stage. Easy to setup and operate. Very stable and high-performance unit. If you need more information about the transmitter feel free to contact me please.
