So there are two separate projects with the same name that do pretty
much the same thing? The one I'm talking about is
<a class="moz-txt-link-freetext" href="http://www.baycom.org/~tom/ham/soundmodem/">http://www.baycom.org/~tom/ham/soundmodem/</a> which runs on Linux as
well as Windows and Solaris. I have used it for both 1200bps VHF
and 300bps HF packet. It works well with the Linux ax25 stack and
software like aprx or Xastir for APRS purposes.<br>
<br>
It is also a purely soundcard-based software TNC.<br>
<br>
I have some tips on using it here:<br>

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>
<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>
