Bill tried again tonight with N6SS on FST4-300, and no success here decoding. I used both 600Hz roofing filter making a very prominent seen signal N6SS, and tried with the normal 3 KHz rx filter. Tried 20 and 100 FTol. After several rx seen signal passes, there was no decode. TX and RX pan freq were both set at 2000Hz
It seems ok on FST-60, I may have to give up on 300, no more ideas on this.

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. 73 Bill G4WJS. _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
