The Weak Signal Propagation Reporter Network is a group of amateur radio operators using K1JT's MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions. The software is open source, and the data collected are available to the public through this site.

After much struggle, VE6ZC now has a new gamer computer operational. It drives an IC-756 PRO III into a 7 band trap vertical through an autotuner, likely with much loss. Like all good hams, I believe nothing is so good that a little more tinkering will improve. The next step will be a dedicated WSPR transceiver and antenna optimized for the "dedicated" WSPR frequency set.

I took world map screen shots every 4 minutes on 600, 160, 80 and 40 Meters on 20th March, the day of the eclipse.

I turned the bitmaps into short videos of the full 24 hours and published them on YouTube.

Today I left WSPR running on 80 meters during the sun eclips

Up and running.

IC 720A and a trapped vertical.

All works well. Trying out 40M at the moment and running 5W. might try a lower power level.


I am trying RX-only for a while, because I am trying k9an-wsprd on the Raspberry Pi 2. So far I am impressed, seeing up to 11 decodes per cycle and weak -27 db signals regularly. I haven't taken accurate measurements, but I estimate it takes 30 seconds to decode the WAV file.

Very odd spot this evening on 17m,

Which when plotted on the map says northern Iraq... Has ISIS started a propagation study?

2 Meter WSPR activity has been happening daily for years in the California area (and elsewhere!) and I was happy to be a part of that effort when I lived there in the Bay Area. You can read of their exploits, as well as other VHF and UHF WSPR activity here ---->!forum/2-meter-wspr

Hi Guys! We now started on 50.294500 in Kyiv. KO50GK - Now using - U3S(Thanks Hans!!!) - ( U3s+GPS+OCXO) and GP. In next step - 5w+3el to Eastern Europe

We have setup OY6FRA to run on 80m now and during the total solareclipse on the 20th
There will maybe aldo be a wspr running on 160m


Dear Guys,

let your rig running during eclipse at the morning of March, 20th 2015 . Hopefully we can detect effects.

Help to set up Kenwood ts 2000s and Signalink USBfor WSPR and other Digitalmodes.

Well, I wasn't into Ham Radio for a while, but the mood has struck again. So I'm back. Finally got WSPR and WSJT-X up and running. Having some fun.

So, at long last, I have finally installed WSPR and got it going!
Now trying to learn what it all means!

Fun, another new dimension of the hobby.

73 to all,

Time is critical running WSPR. For those operators in The Netherlands and surrounding countries here is a list of some Dutch NTP servers with low ping, which you can add and set as standard to your Windows internet time:
