Not sure what happens when Joe is almost on the same frequency. Quite different code settings so each signal is spread out to just become a slight increase in background noise for the other. My guess is negligible effect unless one is a lot stronger than the other. Distance W4DEX to RN3AUS is huge: 8280 km. That's going to be tough! No carrier measurements to suggest code settings or estimate how many nights to stack. One character messages, they are problematic with false decodes at low rank and high Eb/N0. All you can do is let the decoder decide the strongest and report that. Two chars is better in that respect. -- Paul Nicholson --
