yes, that was happening at my end. The soundfiles were recorded with a
homemade sdr. The LO has only a simple crystal, works good for CW and
QRSS3 but not for WOLF. With this rx I'm recording the whole 500 kHz
band every night between 21:00 and 06:00. When Jim announced the WOLF
transmission I was already sleeping. So I used the recorded soundfiles
for the decoding during the day.
