Andy, I didn't notice your message until around 10:30 pm EDT. Found your 
signal immediately with Spectrum Laboratory set for QRSS3 bandwidth. 
Took awhile to figure out Jason software has an offset with my SDR-IQ 
and soundcard. But even with your signal centered, decoding was lousy. 
In 5 sequences not one produced the correct "KU4XR/B", though all were 
close. Yes, there are lightning crashes and QSB tonight but the 
waterfall looked clean enough to correctly decode even by eye. Jason 
sure could use some error correction capability. WSPR, with strong FEC, 
is much more reliable, but Wolf is the ultimate for sensitivity (at even 
lower throughput of course). I'll send you a screen capture direct.
