Hi Rick,
FYI, our tests last night indicate that MFSK16 still copies the best at low
S/N, but only when there are no static crashes, but DEX16 or DEX11 have much
fewer errors when there are static crashes. The problem with MFSK16, as you
found, is the mistuning tolerance. For messaging, when
The problem with knowing where to tune any signal can be solved
completely by use of RS ID (as in MultiPSK, PocketDigi etc). It amazes
me we have had this technology for over a year now and very few people
seem to realize the potential of this.
Even with s/n ratios down around -15dB MultiPSK

That is interesting that they are going to name a new mode DEX that is
similar to, but not the same as DominoEX. I liked using DEX as the
acronym for DominoEX. But the creator gets to pick the names.
I am very pleased that Murray is helping to develop a mode for NBEMS and
I am sure many of us
You know what? I have not used RS ID much as of late and it never even
entered my mind to use this last night. But then again, both stations
need to use Multipsk for that to work.
Are any other programs going to be adding the technology?
