Today I had fun playing around with WSPR 2.0. WSPR stands for “Weak Signal Propagation Reporter” and is part of the WSPRnet.org reporting network. Basically a bunch of Amateur Radio OPs run the WSPR software and connect it to their rigs. Using 5 watts of TX power it then broadcasts over set frequencies that are listening for reports. All then data then gets uploaded to the WSPRnet.org site and then is displayed on a map to show propagation.
Check it out here: WSPRnet.org Click map, then plug in my callsign in the entry box below the map to see stations that have heard me, or click on my call to see stations I have heard.
