A Pll Controlled Professional 100 Watts 550-1750 Khz Am Radio Transmitter

  

With proven quality of ORIENT100. This transmitter utilizes a RF output stage consisting of one power IGBT.

It's frequency can be adjusted by a 8 Bit DIP switch unit and performs an excellent frequency stability. This transmitter runs on 20-30 volts DC. Also you can connect a microphone preamplifier if you want to transmit your voice. It operates on 20-30 Volts DC (DC power supply operated) (power supply not included).

For better operating conditions I recommend an antenna tuner. Tunable on any desired frequency within it's coverage. A single power IGBT as PA stage. IRF540 mosfet as RF driver. BD139 AF transistor as modulator stage.

MC145106 PLL chip as PLL controller. Operates on 20-30 Volts DC 5A. Easy to setup and operate. Super stable and high-performance unit.
