Their website (https://catsat.arizona.edu/mission/ham-radio-community) also mentions a 5 GHz linear transponder. Our National Frequency Allocation Program 2022 mentions "5 830-5 850 MHz (shared with other services) for amateur and amateur-satellite (space-to-Earth)". Wonder whether the CatSat 5GHz linear transponder is in that range. I am hearing of a 5 GHz satellite linear transponder for the first time.

Hi all,

Can anyone please provide the good oil relating to the 10gHz downlink on the recently lunched CatSat satellite please?

Is its reported (IARU) downlink operational, what size of dish required etc etc? I had previously understood this downlink was to rebroadcast HF FT8 and WSPR signals as received by the satellite??

Thank you in anticipation.
