Just saw this on Hackaday. Es’hail-2: Hams Get Their First Geosynchronous Repeater
Now where do I get a transmitter for 2.4GHz? Oh I know I could use the lightning modified router…
“The repeater was engineered with two main services in mind. The first is a narrowband transponder intended for phone (voice) contacts, continuous wave (CW) for Morse contacts, and some of the narrow bandwidth digital modes, like PSK-31. The other transponder is for wideband use, intended to test Digital Amateur Television (DATV). The wideband transponder can carry two simultaneous HD signals and a beacon broadcasting video content from QARS. Both transponders uplink on the portion of the 2.4-GHz reserved for hams, while downlinking on the 10.4-GHz band.”
USA Amateurs need not apply…HI!
“But for hams anywhere from coastal Brazil to Thailand, the satellite is visible 24 hours a day. The equipment to use it can be a bit daunting, if the experience of this amateur radio club in Norway is any indication. They used a 3-metre dish for the 2.4-GHz uplink, along with a string of homebrew hardware and a lot of determination to pull off their one contact so far, and this from a team used to bouncing signals off the Moon.”
There is a Wikipedia page for it:-
Once upon a time a downlink on 10GHz was unheard of for radio amateurs. Now it is possible to do it at a reasonable price…
