This is for used working Millenium DX radio systems power amplifier made by TPL. It is tuned to 147.420mhz ham band frequency with 5~7 watt input produce 100 watt output. I tested this with my motorola communication analyzer as seen on pictures. The panel meter will measure forward and reflected power and works too. The fan runs at low speed when cold and high speed on hot temperature.Comes with power cord, and short pigtail cable with both bnc connector at the ends. Power requirements is 13.8v at 25amps or more for continuos duty cycle.Please note that this do not have a tx-rx changeover relay and cannot be use on a regular transceiver. If you have further questions or concerns let me know. As with all electronics this is sold as-is but will not be DOA when you receive it.
