They are much appreciated. As far as I can see they decode just about as expected. See http://physics.princeton.edu/pulsar/K1JT/G3ZJO_files.png for my results with yesterday's current version, WSJT-X v0.2 r2706, which I had assumed you were using. Your Rx log file shows very different decoding results, including many garbage decodes. Perhaps you had not upgraded to r2706, after all ? You have also posted some strange looking results produced when trying to receive your own transmitted signal. JT9 is a weak signal mode; while tweaking the performance of the decoder, no effort has been put into making it work on very strong signals. There are numerous ways to make laboratory-style tests -- Tx to Rx in your own shack -- but just receiving the signal with S/N >> 0 dB is not, in general, going to work. -- 73, Joe, K1JT
