<pre class="moz-quote-pre" wrap="">Over the weekend of the 6th and 7th of January , I conducted a road test comparing the performance of APRS over traditional HF 300-baud AX.25 packet vs APRS using the VARA modem on 60 meters. This was a 500-mile round-trip from central Michigan (East Lansing area) to west suburban Chicago and back. VARA was overwhelmingly superior - by least an order of magnitude!

Are you planning on doing a comparison between VARA and PSK63 or MFSK16?

<p><font face="Arial">Yes, I plan to try this on an upcoming road
trip to the Traverse City Swapmeet on Feb 11. This is about 150
miles / 240 Km to the northwest of my home location, so should
be a good test of medium-distance NVIS propagation. <br>
</font></p>
<p><font face="Arial">Before then, I need to re-jigger the
serial-KISS to TCPIP-KISS connections on my main HF APRS
webserver. <br>
</font></p>
<p><font face="Arial">Currently, the KISS-over-IP port of FLdigi is
being bridged to the KISS-over-serial port of UIview with a
kludge of the open-source com0com utility combined with it's
companion COM2TCP utility. <br>
</font></p>
<p><font face="Arial"><br>
</font></p>
<p><font face="Arial">I am now replacing this setup with the comport
tools in Eterlogic's VSPE (Virtual Serial Port Emulator). These
freeware tools allow you to construct a variety of virtual COM
port devices including null modems, one-to-many splitters
(useful for sharing a GPS data stream to more than one
application at a time), serial<-->IP bridges (both client
and server TCPIP), and a unique device -- the "serial
connector". The "connector" is like a virtual null-modem except
that both ends have the SAME com number. <br>
This allows two serial-using applications to connect to talk
to each other by both selecting, for example, "COM8" - thus
conserving COM numbers in complex setups. Especially valuable
for older legacy software like UIview (and many others) that
only know the first 8 COM numbers. <br>
</font></p>
<p><font face="Arial">VSPE has a complete GUI interface that lets
you create, modify or destroy these various "widgets" without
editing command lines, .ini files, or endlessly rebooting to
make changes effective. You can save your multiple constructions
into a " .VSPE " file that can reload your setup on demand with
a single double-click. <br>
</font></p>
<p><font face="Arial">Finally, I have found that VSPE widgets are
really bullet-proof stable, and have far better error recovery
that widgets built with com0com. With com0com, startup sequence
of the various apps in my setup was critical. With VSPE, you
can start stuff in any order, and they just "take off and fly".

<p><font face="Arial">The 32-bit version is free, and will work on
64-bit Windows systems. The native 64-bit version (USD $25)
contains Microsoft-signed drivers for Win 7-8-10-11. This allows
you to configure widgets as Windows system services that load at
boot. <br>
