Its still going.

At 1611z I ran rsNTP and it made a PC clock adjustment of 0.4 seconds, which with the 0.5s symbols used for this transmission will glitch slightly .

Pleased to note that a local recording I made using the  new LF Receiver hardware and my own software to generate a .WAV file compatible with Spectrum Lab's did generate a valid decode. Recorded at fs = 31.25Hz  That was before the PC time had been corrected and I had to do a fair bit of shuffling with the Start Offset value to get a decode.   Values from 0.45s to 0.85s worked - much of that presumably due to the PC time offset in the transmission.   But once a value in that range had been entered, zero decode errors - which is what one would expect of a very strong local copy !

It does appear that using EbNaut with rates much faster that 2S/s could end up very fraught with timing offsets.  Fortunately, weak signalling with longer symbols of several seconds will have less of a problem with timing offsets.
