Jim, WA3LBI, will be the operator for 10 GHz EME using JT4. We will be using his portable 2.4 meter dish and a 250 watt TWTA.
If you can hit the moon with a 1 meter dish and a few watts, we would like to work you. Jim has worked VK7MO who has 45 watts and a 77 cm dish (approximately 3 feet).
Details: PE1RKI feed with circular polarization and two WR 75 connections (TX/RX). A Kuhne 03 10 GHz transverter with GPSDO 10 Mhz reference.
A low cost method of receiving 10 GHz EME signals can be found on PA0EHG's site.
