If you look at the big table at the end of http://abelian.org/ebnaut/ops.shtml you can see there's no further improvement in success rate for 6 bit payloads (1 char plus zero CRC = 6 bits). The reason appears to be the payload is simply not long enough to make full use of the longer constraint lengths. > On Pauls side the SNR is equal, day and night. Ah, not always. We now have Night 2nd/3rd: -24.26 dB in 1Hz, phase 34.9 deg Day 3rd: -24.31 dB in 1Hz, phase 100.1 deg Night 3rd/4th: -32.16 dB in 1Hz, phase 24.3 deg Day 4th: ... For some reason, the signal last night was about 6dB weaker. -- Paul Nicholson --
