Where can we get more information about the soundmodem project?
Is that the same one that is used on Linux?<br>

This has nothing to do with Linux. <br>

The UZ7HO "Soundmodem" is a purely soundcard-based dual-port
software-based TNC for 300, 600 and 1200 baud packet operation on
any version of Windows beginning with Windows 2000. <br>
<br>
It's a drop-in replacement for the AGW Packet Engine used in it's
sound card mode (i.e. not in AGW's role as a port manger sharing
multiple TNCs with any number of packet-using apps). The
Soundmodem exactly mimics AGW's API, and will work with any program
currently offering an AGW option as an alternative to a hardware
TNC(s). Some of the programs that support AGWpe (and thus the UZ7HO
"Soundmodem") are WinAPRS, UIview, APRSpoint and APRSis32. <br>
<br>
Compared to AGWpe:<br>
<br>
<ul>
<li>The soundmodem is less tweaky and touchy about sound card
setup, timing and audio levels.<br>
<br>
</li>
<li>The soundmodem can be set to any desired audio tone pair on
300 baud HF mode, in a manner similar to most PSK31 programs.
(The freeware version of AGWpe is fixed at 2100/2300 audio tones
on HF which causes problems with many HF/SSB transceivers with
narrow passbands. The pay-for AGWpe "Pro" version does allow you
to select the KAM-style 1600/1800 tone pair that is much less
problematic with SSB transceivers. The Soundmodem lets you use
ANY tone pair -- for example selecting a tone pair that matches
the passband of a 500 Hz CW filter in the radio.)<br>
<br>
</li>
<li>In addition to dual waterfall displays (one for each port),
the Soundmodem has a built-in raw packet display that allows you
to immediately see if it is functioning correctly and decoding
packets, without needing to start up an external application.
Very useful for debugging initial setups -- it immediately
eliminates the uncertainty of whether "no decode" problems are
in the link between the soundcard program and the external
application, or inside the sound card and sound card app itself.
<br>
<br>
</li>
<li>The soundmodem is the highest-performing packet TNC for noisy
HF modes that I have ever tested. It runs circles around any
hardware-based devices such as PK-232s or KAMs. <br>
<br>
</li>
<li>And finally, it is FREE!!!</li>
</ul>
<p>Despite it's rather sophisticated DSP, I am using this soundcard
app combined with UIview on a mere 877 MHz Pentium III, and on an
Acer ZG-5 Netbook with a 1GHz Intel "Atom" processor (i.e. rather
wimpy CPU), with no difficulty. The original site for the
Soundmodem is the author's website at:<br>

I have repackaged the original "dumb zipfile" distribution into a
full-blown standard Windows "wizard-type" automated installer that
includes a user manual, creates a Windows Start Menu group, desktop
short cuts, etc. Download it from my website at:<br>
