The only difference is that Jason goes 5 times faster than QRSS (at same SNR). Or if you want ho transmit a certain text within a certain timeframe, Jason will produce a 7dB better SNR compared to QRSS. To achieve 7dB improvement by just increasing power I would have to go from the current 400W I'm running to 2kW, so Jason has clearly a big advantage for me (and maybe I'm not the only one). I really appreciate the work done by the software developers (such als Alberto and Wolf) and those who often do the first tests and investigate propagation (many at both sides of the pond ...). They pave the path that other (such as xxx) can easily walk on afterward. 73, Rik
