10 GHz narrow band transceiver base on the famous ' White Box'
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
