Hi John,

That may be premature, because the RFSM is still under development,
going through changes as we speak.

The MIL STD 188-110 standard and FS-1052 that RFSM uses, is printed by
the US Govt, for general release, it is a public document, and this
qualifies the -110 Standard 8-phase PSK part of the RFSM2400 for
"street legal" for USA hams in the Phone/Image sub-band if the content
is Fax, Image, or Voice.

For those USA hams who are interested in using RFSM for Texting, FTP,
and email, in the RTTY/Data subbands, there may be some interesting
developments coming soon on this. I've noticed that there are already
many US hams experimenting with it, so it appears that there is a huge
popular demand for it :)

There is a non-standard part of the RFSM that is 6-phase PSK, and it
appears to follow the 8-phase govt standard. This non-standard part
may need to be documented and posted on a public website. If and when
I am able to get it in an appropriate format, I will put it on the
public part of the HFLINK.COM website. Anyone can download it from
there, and of course, ARRL can put it on their technical information
site also if they want to.
