style="FONT-WEIGHT: bold"></SPAN>WSPR implements a protocol designed for probing
potential propagation paths with low-power transmissions. Normal
transmissions carry a station's callsign, Maidenhead grid locator, and
transmitter power in dBm. The program can decode signals with S/N as low
as -28 dB in a 2500 Hz bandwidth. Stations with internet access can
automatically upload their reception reports to a central database
called <A href="http://wsprnet.org/">WSPRnet</A>, which includes a mapping
facility. To see a live version of the map pictured at top right,

<P><SPAN style="FONT-WEIGHT: bold">WSPR 2.0</SPAN> introduces a number of
new features including a user-friendly setup screen with drop-down
selection of audio devices and rig-control parameters, support for compound
callsigns, fine selection of the fractional time for transmitting, and
a <SPAN style="FONT-STYLE: italic">Tune</SPAN> button. A

User's Guide</A>, which you will need to read in order to use the new
features. For the first time, a binary installation package is made
available for Ubuntu Linux (versions 8.10 and later), Debian 5.03, and other
Debian-based 32-bit Linux distributions.<BR></P>
