Cannot say anything about the uplink sensitivity but the downlink signal certainly is very strong! This time I will not be limited by receiver sensitivity, that is for sure.
(sometimes this has been an issue with earlier Phase3 sats)
When the transponder is officially released of course I will try with my 2 Watts as well. Maybe it could work, especially before the aligators get there.
However, with this bird there should not be a reason for being aligator.
