I would make more sense to me, in my humble unbiased opinion, to have someone in the footprint of Es'hail to put together a ground station that that is also an EchoLink node. That way, anyone in the world could potentially access Es'hail via EchoLink. It would be an interesting exercise, anyway.

Hi Dave, Nader, A CubeSat Converter is certainly an interesting thought. In addition to the challenges (that's the hip cop-out from saying "problem" these days) that you noted, I'm thinking that the ConverterSat would also: Have to be in the footprint of Es'hail So as a converter even only in the footprint for stations in the footprint but w/o the S and X equipment, it would only offer a 10-20 minute window to Es'hail the usual 3-6 times per day In trying to extend the footprint, it would need to be of a pretty high altitude itself in order to extend the footprint by much Being on the edge of the Es'hail footprint in order to extend it, requires more power/gain/pointing to connect with Es'hail But I guess these are more "usefulness" challenges than the RF challenges of acting as the converter you have listed. It gave me thoughts about GOLF-TEE trying to bridge the gap, but would have design implications as you noted that at least wouldn't be possible in our current timeline.

Hi, Interesting idea. Problems to overcome: Size of dish / patch required to be flown as part of satellite Attitude control and pointing in real time Power management Band width limitations Doppler correction Frequency stabilty Any more folks? Dave, G4DPZ
