Hi Tobias,

I do not have timing problems at WSJT-X despite my SDR has long latencies.
Yes, many users have no timing problems in the latest JT9 versions but there are still many users left, who do have timing problems! In WSPR, no one has timing problems, as long as a time server program is used. I never ever observed timing problems in WSPR... Obviously the decoder is very critical against a time delay. This seems not to be relatives by the mode (1,2,5,10,30). For example i saw several non decodes at UA0SNV, having 10 sync points and realistic SNR showings but no text was displayed. However there was one decode showing my message. This is the current situation...
