Hi,
This was a thread a couple of weeks ago, just when I got kicked off the
reflector for too many bounces (due to my efforts to filter out the horrendous
crap and clutter at that time). I had wanted to mention TrueTTY as
another useful decoder, although it cannot be used in N1MM. I find it falls
somewhere between 2Tone and MMTTY.
I've used fldigi too, but have had trouble using it in N1MM where sometimes
it stops decoding for some unknown reason. In my experience the
decoders I've tried fall thusly:
2Tone > TrueTTY > fldigi = MMVARI > MMTTY
but, as I've said before, on any given transmission it's a crap shoot.

The trade off between a "low-latency crummy decoder" and a "high-latency
better decoder" can be solved if you allow new GUI elements into your
modem.
Run two demodulators. The low-latency one prints first. The high-latency
decoder then overprints over those characters when they become available
from the high latency decoder. This way, your eyes do not need to switch
its focus between two windows. Strong signals will print correctly right
away.
Variations on this theme include using two different color fonts that
produces a third color when the two decoders agree, etc.
I had discussed this technique before with G3YYD for making even longer
latency decoders tolerable (for example, ones that corrects bit clocks by
using "future" bits for pseudo-synchronous clocking). But David is hobbled
by the existing modem user interfaces.
