Jay, your signal is holding in there in the high teens SNR. Yesterday 
your QRSS45 was good copy the entire day. Last night when XNS and XEB 
were both sending WSPRX-15 my e-probe/SDR-IQ combo produced significant 
IM3. Both your signals were of comparable SNR but XEB decoded on the 
LSB, which was in-band.

Not sure why nothing decoded at 0445Z. Had misses later with DK7FC too. 
Specified "Save all" to assist troubleshooting but that didn't save 
anything so stopped and reran the program to clear whatever the hangup 
was. Do need to remember that like regular WSPR nothing will decode 
until the first partial interval is completed. That can take nearly 15 
minutes worst case with WSPRX-15.
