Mike,

going from QRSS3 to QRSS10, when using Argo, means that the FFT bin size is 4 times smaller, and this results in an increase of 6 dB of SNR, provided the useful signal is still confined into a single bin. If you are in "experimentation mode", you could also arrange a comparison between QRSSxx and Jason at various speed. That could be interesting.

This morning, I worked a new station for me (No:103), DL3ZID. He first called me on DFCW3, but was impossible to read. He then changed to QRSS3 which was an improvement, but not 100%. A change to QRSS10 gave a really clear easy-to-read signal.
