Duty cycle was at 25% all evening and offset as clear as possible 
from other stations.  Only other US station was WF2XXQ running 
50mW from FL around 775 offset and WE2XGR/6 at 50W ERP up at 
499.5 kHz.

It appears your soundcard/audio levels may be overloading or 
something else in the signal path creating images, based on the 
multiple decodes per session.  There were other stations decoding 
at the same SNR without multiple decodes and able to copy other 
stations in the same session.  WSPR is pretty good about handling 
wide SNR ranges.

73 - Eric NO3M, WG2XJM
