I downloaded the latest version of NBEMS yesterday and hooked up with WB8NUT. PSK31 was a tough copy so switched to
MFSK. Successfully transferred a 750byte file in 210 seconds ARQ. Also liked the chat function in Flarq, works well. I tried the same text file with different modes to see what the TX times were, and came up with the following: Standard 750 byte file, no ARQ unless noted MFSK : 2 minutes, 10 seconds PSK31: 2 minutes,30 seconds PSK63 : 1 minute,16 seconds PSK125: 37 seconds RTTY (45) 2 minutes 31 seconds Olivia (500/8) 4 minutes, 17 seconds ALE400 (ARQ) 2 minutes, 15 seconds Surprised that MFSK is a little faster than PSK31.... and works better under the generally poor conditions we have lately John VE5MU
