Thanks, that site has all sorts of ham software a lot of it for
Linux/Windows. Digital modes is something I have not tried before and
I want to get involve so this will help a lot, I mostly run Linux myself.
I use Puppy Linux on a old laptop for it's speed and also to rescue
data from PC's
What Linux app would you recommend that offers DominoEX,
especially DEX11 = -12 and DEX22 = -9 with and without FEC?
I am in the midst of a major reorganization of my radio
room and may dedicate a Kenwood TS-180 to digital modes,
including DominoEX and also sstv, dsstv, PSK31, etc ...
seems
Hi,
I *have* to use HP-UX at work so I avoid it and anything that reminds
me of it at home; but think your only real choice would be Fldigi
See http://www.w1hkj.com/Fldigi.html
Others that use Unix/Linux might offer other options...

I did not see any response to this but each of the DominoEX modes does
have an estimated SNR
For example:
DEX4 = -14.5 dB
DEX5 = -14
DEX8 = -13.5
DEX11 = -12
DEX16 = -10.5
DEX22 = -9
Add about one 1 db better SNR for using the FEC mode.
It does seem that DEX22/FEC works better than

I was not aware that the lowest S/N ratios allow for significant error
rates. For example, the British study had what seemed perfect data
throughput when they listed the S/N ratio below noise, although under
AWGN and that is more similar to VHF and up compared to HF.

Also, they are different types of modulations.

Hi Rick,
That pretty much echos my experience too...DominoEX at 11 baud seems
to be the best compromise for 80/160.
Unless the S/N ratio is pretty high, I have not had the best of
results with either CHIP or MT63when S/N levels are high these
modes work very well.
As for
