Yup, saw that, but it is non-specific as to the interconnect between uplink/downlink and the modes that we'll be able to run through it.
I'm looking up how to get 76 GHz going. :-)

I have gear to receive the 76 GHz band. I've sent a note to the Cuava team to ask about TX power, EiRP, antenna etc to get a sense of what it might take to at least detect the downlink.

Wow, this is a major leap towards these bands.Wonder how the frequency allocation is for Amateur satellite service at 76 GHz. 73 Nitin [VU3TYG]
