<p>VARA is a relatively new soundcard-based "digi-mode". it is
essentially a software-based modem or "TNC" that can work
reliably at extremely low signal-to-noise ratios. With a strong
signal, it can achieve speeds exceeding 1200 baud packet in a
500 Hz CW bandwidth on HF/SSB. VARA is only a modem - some
application software with an IP or KISS link like a messaging
app or email needs to run on top of it. </p>
<p>Some details on VARA and how to mate it with APRS applications
is here on my website:</p>

Shows using APRS clients with VARA as a vastly superior means
of HF APRS beaconing. <br>
