Jay, Rob, Markus, Stefan, Joe, LF


Jay, thanks again for the decode: congrats for your rx setup.
And thank you so much for trying, Rob.

Here, the TP2 reference signal (not sufficiently filtered) overshot sometimes the quadrature divider (x4) causing that phase jumps. The problem is now fixed.

A new TX EbNaut session is scheduled for starting tomorrow evening.

All the best

Stefan ... good copy throughout the night. Riccardo ... unfortunately only one decode to report. Markus noted a frequency error ... curious if propagation or NE0-M8T?
