It's even more amazing how far 0.5 watts can be heard and information exchanged using human brains as the encoder/decoder software.
You can tell how far a few watts, even 100 mW (0.1 W) can be heard by simply tuning in the NCDXF/IARU beacons on 20 through 10 meters - no computer, no special software, just your receiver and your ears needed: http://www.ncdxf.org/beacon/beaconschedule.html Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of gold...@charter.net Sent: Monday, May 30, 2011 7:02 PM To: Wes Stewart Cc: elecraft@mailman.qth.net; Max Kempson Subject: Re: [Elecraft] WSPR It actually works fairly good. You dont get confirmed contacts per say, but you can see your propagation information via a map on the web. Its actaully fairly amazing how far 0.5 watts can go. I also now know what another signal looks like on the DM780 trace. I played with it today and its another tool in the toolbox to see what my antenna is capable of doing.
