Distant whispers? WSPR, or the Weak Signal Propagation Reporter network, is a group of amateur radio operators probing radio frequency propagation conditions using very low power transmissions. WSPR produces a propagation map that can help hams choose which band to operate at any given time.
A great article explaining WSPR is available at http://www.g4ilo.com/wspr.html. You’ll get a full explanation of how it works, how to install and use it, and the benefits you’ll enjoy from WSPR.
Think CW is sufficient? How about a real difference of 11 to 15 dB in favor of WSPR? Link: http://g3xbm-qrp.blogspot.com/2009/08/wspr-versus-cw-whats-improvement.html.
HI ALL,From what I have read so far The WSPR propagation program looks like it would be a very handy tool for checking out band openings. Made for some good reading.73 de kc7uss
