MFSK-16/32 good for weak signal work.

We had an excellent chat on the Saturday TDRC "fun" net on 40m between one other station and I.  I had an opportunity to demonstrate the various capabilities of the FLDIGI suite to transfer files and emails from station to station.

There was some fading on the band right after the start of the net, which made higher speed PSK-125 and PSK-250 difficult.

For similar throughput, we changed to MFSK-16 and had 100% copy at a slower data rate (considering the number of times we had to retry in other modes).  Keep in mind that MFSK has some FEC (forward error correction) built into it, plus the mode is generally more resistant to fading and other "intermittent" sources of interference.

We may consider MFSK-32 as a mode for our APRS experiments!
