Hi Adrian,

the differences you see are due to you having "Settings->General->Single 
decode" checked and N6SS not. In single decode mode the decoder only 
attempts to decode signals within the selected  Rx offset and frequency 
tolerance around that, only the first successful decode is printed. With 
single decode not checked multiple signals may be decoded within the 
specified low and high frequency limits after an initial decode attempt 
at the selected Rx offset ±20 Hz.

You have not provided enough information to determine the one way 
decoding, but the above should allow you to assess if it was merely a 
settings issue.
