Ham Radio Geostationary Satellite Transponders

An article by Dan Maloney KC1DJT about the new Es'hail-2 / QO-100 amateur radio geostationary satellite transponders

For the reception, a dish in the 60-cm to 1-meter range will suffice, depending on location, with a decent LNB downconverter. Pretty much any SDR will do for a receiver. An alternative to assembling the hardware yourself — and the only way to get in on the fun for the two-thirds of the planet not covered by the satellite — would be to tune into one of the WebSDR ground stations that have been set up.

The British Amateur Television Club and AMSAT-UK, located at Goonhilly Earth Station, have set up an SDR for the narrowband transponder that you can control over the web. I used it to listen in on a number of contacts between hams the other night.
