I am looking to put together a station for the Es’hail-2 geosynchronous satellite that is about to be launched. Amsat say: “Qatar’s Es’hail-2 satellite will provide: “… the first amateur radio geostationary communications that could link amateurs from Brazil to Thailand.” It will have a narrow band linear transponder with a 2400.050 – 2400.300 MHz uplink and 10489.550 – 10489.800 MHz downlink plus a wideband digital transponder which I will not be using.

At the Microwave group stand at the RSGB convention last weekend I saw a domestic satellite LNB connected to an SDR RX running at 613Mhz. I have the RSP1A and want to try it with an LNB and a 100cm dish for the 10Ghz downlink. The uplink is a bit more complex and I can only think of making a 13cm transverters. There are some kits around, but they are not cheap, and I do not need the RX portion.

The ideal would be conversion of suitable commercial gear. I like to hear about any ideas, suggestions you have especially if you doing something similar. Use email ‘m5fra’ at this site address if you can help. Thanks.
