ARLA/CLUSTER: Rede WSPR- Weak Signal Propagation Report

[João Gonçalves Costa]

Description
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 WSPRnet<http://wsprnet.org/>, which includes a mapping facility.  To see a live version of the map pictured at top right, click here<http://wsprnet.org/drupal/wsprnet/map>.

WSPR 2.0 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 Tune button.  A new Advanced setup screen offers optional CW identification and tools for frequency calibration and automated frequency corrections for your radio.  Full details are presented in the WSPR 2.0 User's Guide<http://physics.princeton.edu/pulsar/K1JT/WSPR_2.0_User.pdf>, 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.

WSPR 2.11 is a beta release that includes two major enhancements:
