Geostationary Amateur Radio Transponder Talk and Demonstration

On Saturday, October 14 at 1:45pm BST (1245 GMT) AMSAT-DL President Peter Guelzow DB2OS will give a presentation on the Es’hail-2 Geostationary Satellite Amateur Radio Transponders to the AMSAT-UK International Space Colloquium in Milton Keynes.

It is expected the presentation will include a demonstration of the P4A transponder simulator. All attendees are welcome to bring any equipment they have for CW/SSB or DATV for the 2.4 GHz and 10.5 GHz bands. The transponder mimics the real thing: 2400-2410 MHz uplink to 10489.5-10499.5 MHz downlink.

This year the AMSAT-UK Colloquium is taking place as part of the RSGB Convention at the Kents Hill Park Conference Centre, Timbold Drive, Milton Keynes, MK7 6BZ on the weekend of October 14-15. Tickets to the event are available at the door or you can book in advance at
