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.

Well, I've been WSPRing for about six hours far, my farthest report has been So. Australia. I'm getting ready to get packed up for the night, but might leave my computer hooked up and in Idle mode just to see what comes across through the night.

Anyway, if you read this, drop me a note at kd7yzd[at]arrl{dot}net. This blog may or may not survive, but I'm going to see if this can be a more personal beacon through WSPR.


Here is the screen received 2day june30 meanwhile nothing from usa even have a qso even have a qso with W1JJ a few minutes before.

Hello everyone,

I've just reconnected my 2metre 5 element Jaybeam, over here in IO71lu.

For the next week or so I'll be QRV on the 2m WSPR frequency. Mostly between 7.00pm and 10.00pm.

The antenna will be fixed beaming east ... I'm only running 5 watts

No idea if it will be successful, but you never know...fingers crossed :o)

MW0MJB Loc IO71LU Pembrokeshire .....

Hope to see you in the log :o)



I started today the frequency hopping between the 6m(6elts) and 2m(13elts)using the IC746.The CAT works without any problem.
Still not receive any spot from the 2m yet but hear CT & EA chatting .

Hi all.

After a long period of time being off air I will be QRV 5W in 20m from about 0000Z to 1200Z (full night local time) for about 5 to 6 days starting last night (23/06/2011 UTC). That will be hard work for the PC processing videos all night, and the radio will be on about 10% TX.

The spots will be uploaded asyncronous with about 12 to 24 hours of delay because the lack of internet at home.

Last night best archeivement was 2 VK land station, yahoo!!!

Finally scrounged a decent computer for weak signal work. Completed it today. Put up my experimental antenna last weekend. Haven't heard a WSPR out of anybody on it yet, but I have faith it will work. Eggbeater II for 6m. Elevated over my metal garden shed for ground plane. According to EZNEC it should work much better than a vertical or a dipole and offer both vertical and horizontal polarity with 6dbi gain full circle up to about 45 degrees and 0dbi to the zenith. 73, Roger

is spelled Carolina. How do I correct this incorrect entry?


Having had numerous computer problems in the last year, I've decided to purchase a PC to specifically run applications for amateur radio, I've introduced applications one at a time and managed to get the data modes working well.

I've started WSPRing at 5W, I will begin to lower the output on a regular basis once I get a feel for how things work, I'm also looking at working a few of the regular sessions, interesting times ahead.



I received on june 18 KA1MDA around 20h00 and agn on june 19 around 18h00 with K1JT. Monday june 20 i received agn K1JT but around 13h00.Pse see the attachment.
For all the spots above i was far from my shack.

this evening i was receiving stations on 14.0956 on my portable Degen DE1103 receiver.
Antenna was an indoor magnetic loop. I am surprised that stations could be received so well!


on you can see my WSPR loggings. It uses mySQL, PHP and Google Maps API to build a map with all received Stations. Like But for long term. Not only 24 hours...

Have fun...

BTW: 2011 isn't in database, yet. 2bcontinued...

My activity on 2011-06-15-1924 thru 2336 was done using a 11 meter 5/8 wave antenna on 20 Meters. Power was 5 watts from a FT897. I had over 50 hits which surprised me. FYI to all who were reported by me. Thanks all.


My station has been active on 6 meters since 9 June 2011. There are many uploaded 6 meter spots among European stations these days but I see almost no 6m WSPR spots in the Americas despite hearing SSB QSOs via sporadic E skip. Can those of us with the capability activate 6 meters on WSPR?


With freeware CamStudio you can make quality video clips from screen captures of your PowerSDR or other panadapter and waterfall displays. I have posted such a video that shows WSPR signals being decoded at

At times I have observed PowerSDR go into a state where all transmitted and received signals have a loud superimposed buzzsaw sound, about 20-30 Hz or so. It has been responsible for erroneous multiple simultaneous decodes of the same stations both on receive and transmit. I suspect it has to do with hardware interrupts as it seems to occur after I've used the computer for a CPU intensive task like watching a video while PowerSDR is running in the background. Stopping and restarting PowerSDR with the Start button usually seems to clear this problem.

Homebrew interface from PC to Alinco DX-70TH now working. Looks like the rig is a tad off frequency though, i kinda suspected this from voice QSOs. Will carry out netting procedure later. For time being, im now beaconing on 20m.

The new interface is very simple, but has some 'odd' features. For one, the rigs microphone now plugs into the interface, not the rig. This is good as the mic socket on the rig is hidden behind the fascia and is a pain to get to. The other feature is a through connection from the serial cable to the FRG-100 CAT interface.

Last night (13-06-2011) I tested my antenna on 40 meters with 0,5 watt power.
The results ware not bad.
Best result: PU2MWD spotted me on 22:16 with a SNR of -25. That's a distance of 9912km (6159 mi).
The antenna used is a windom as inverted V, top at 9 meters above ground level.

yesterday i installed WSPR 2.0
Today i was transmitting on 20 and 30 metres. Wow! with my magnetic loop and only 200 mWatts my signal was heard in Sweden and Norway. And with my Cobra dipole my 200 mW was heard in the middle East.

Let us see if this little thing works?

We are now in the season of super-DX Es openings on 6m when the band can open spectacularly across the Atlantic from Europe to the USA, the Caribbean, northern South America. WSPR could be a superb tool to help track fleeting openings over these very long paths, but we need more stations on 6m WSPR for this to be possible.
