Has a modified LNB preamp and a WDG PA. Changeover is by a chunky waveguide switch

I have tested it and it is very sensitive receiving SCX beacon .in my shack on the integral offset dish.

It transmits > 250 mwatts at 10 Ghz for 2 watts 2m input.

Operates on 12 Volts 

Looking £125 plus carriage.
