All,
Had another opportunity to test MFTTY on air today. As expected, sensitivity
goes hand-in-hand with character speed and the slower 1/8 mode is probably
close to what you might expect from say PSK31.
Path simulations seem to indicate that the mode is probably more stable than
PSK31 when
Steinar,
I did test the FEC mode at half speed using the canned simulations from Moe
Wheatley's PathSim and there doesn't appear to be any difference in
performance.
The half-speed mode seems to be quite a bit less sensitive than other keyboard
modes and I would imagine throughput would
Great!
Thanks Tony

All,
I was able to take some time to test MFTTY with the HF path simulator this
evening. I added a few commonly use modes for comparison. As expected, the
slower / narrow MFTTY modes seemed to have a definite weak signal advantage
over the faster ones.
The minimum SNR test showed a wide
copy using MFSK16 (but with a wider bandwidth, of course) when PSK31 started
producing errors.

I used half-speed. I'll test the mode at different speeds and will post the
