The question is whether the K4DSP unit (QST article here for members:
http://p1k.arrl.org/pubs_archive/139117) will even work with 2Tone.
The developer of 2Tone refuses to adopt a fixed frequency mode - it's
AFSK only with AFC running all the time. Since the K4DSP interface
expects to decode fixed frequency tones (2125/2295 or 1275/1445) how
well does it work with "drifting" inputs?
The lack of *fixed* inputs may be a serious limitation with any
regenerator - whether it be the K4DSP design of a simple PLL tone
decoder:

It's not been mentioned on the RTTY list before, just N1MM-digital, and
I'm not getting those emails (not enough bandwidth most of the time).

Obviously, I've missed something- what's "2 Tone" in this context?
Google
isn't being helpful.

It's a new program which can replace MMTTY but only with N1MM.
Check the archives back a week or two.
