Sounds exactly like the packet radio networks and systems that many on
this list have been using for the past 20 years. That's exactly what you
are describing here at first glance.

I wouldn't call it backwards. Ironically, alot of the packet radio networks
from the past 10 years have opted to use internet anyways to forward between
systems (using axip and/or axudp tunnels over the internet). Why ? Too much
distance between systems, and a lack of desire (or money perhaps) to try
and build a pure RF network. I mean why spend tons of cash on radio stuff
when the internet is free (cheap cheap cheap). I'm trying to be funny.

Same here. I guess the reality is that voice is the choice.

For peer to peer VHF, so does Winpack, or PR4WIN, and countless others.
For VHF and HF connection, so do NOS, FBB, and other systems.

This is the part that puzzles me. Why do you think it is so oriented
towards the SCS product. Do the LATEST versions exclude all the other
modems ? The Airmail client I use has allowed me to use an MFJ, a KAM,
a DXP, and of course the SCS. I'm sure the PK232 is in there as well.
Sure, the focus might be to spend the most time on the newer modern
products, but I am able to use my *older* tncs still with more or less

And probably there's not much one can do about that. That's the platform
of choice for the developers. Of course, by doing this, the developers
have given you the freedom to choose :-)

I am guessing that the WinLink developers simply are not interested in
that approach. They have every right to do it the way they want. The so
called market out there will at some point determine if they made the
right decision or not. Isn't that the way all products work ?
If you truly want an open source approach, then ditch WinLink and/or
the AirMail stuff, and look at the alternatives, some of them below :
* The newer generation of software like PSK-Mail (which looks like some
are touting as an alternative to WinLink 2000). I'm sure there is alot
more other stuff hidden out there as well.
* Or the older generation of software like the NOS and FBB systems, and
whatever else people still run.

Comments noted. To me it's a tool, I don't care if it grows or not.

Sounds to me that someone has already decided what to do then :-)

With all due respect, this is the wrong mailing list then.
I am certainly excited about some of the past sound card modes, for example
Thomas Sailer wrote sound card modules that I've tried in linux NOS (kiss
interface). It is SOOO cool, and I'm sure things will get even more exciting.
I would certainly add these modes to NOS, problem is alot of this sound
card software has limited to no API to interface with (please jump in if
anyone has more accurate information). I thought about this over a year
ago believe it or not. I guess one needs to colaborate (or try to) with
the soundcard authors (a sutle hint to myself).
> PSKmail could be used if we get other hams to switch to Linux.
I spent a bit of time last year, seeing how PSK Mail and similar
software did this. The idea was to see if I could use the API used
by PSK Mail within NOS. Anyways ...

Being that voice is so desireable among agencies, one of our senior ARES
people complained that voice is great, but HF voice with tons of noise is
just useless. Enter a new product from AOR communications :
Perhaps this is one way to sell digital to the voice people, in particular
the HF SSB modems (look under products / other ):
DIGITAL SSB WITH ANY HF RADIO!
ARD 9800 or the ARD 9000 MK2 Digital Voice Modem

Yep, I agree. I miss our old WARP group coffee days.
