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.

in the next couple of days we should see first signals from Namibia V51
It is OE1IFM and OE1CSC who will install the new beacon system, that has been built and sponsored by Om Gernot.

Like to get on WSPR with your homebrew rig? Looking for a challenge that goes beyond simple plug-and-play?
Then you should consider the GenesisRadio kit: G3020 is a multimode, 30m+20m duobander with 5W output. Yes, G3020 is no beginners kit but if you are clever and possess good soldering skills you'll get it right too. Homebrewing+QRP=Fun! For more information visit http://www.GenesisRadio.com.au

PS here is an unsolicited report from yet another happy builder:

Hi you all out there,

I have cut a 30m half wave antenna, which is connected to the match-box of my PAR End Fedz antenna. The wire is still indoors, strung down the hallway, and dangles down the stairs, but it seems to work fine. I soon got it on frequency with my home brew antenna analyser. I still want to build and try a magnetic loop to see how the two indoor antennas compare. Will probably use 15mm Copper pipe with mechanical compression fittings, rather than having to buy a blowtorch and flux to use solder joints.

I carried out my first WSPR tests this evening on 30m. Rig is an Icom IC-746 running about 5W, or at least as little RF as I can, and the antenna is an American PAR End Fedz 40/20/10. It runs from the upstairs spare bedroom 'shack', and is tacked to a door frame. The wire then runs down the length of the hallway, then down the stairs towards the front door of our small house. Hardly ideal, and besides, the antenna is nowhere near resonant on 30m with a very high SWR.

Nevertheless - I was heard in Japan, ZL, and USA, and was also hearing stations bordering the Pacific. Not bad given the antenna restrictions!

I hope to either fit a resonant 1/2wave indoor wire up for 30m, or alternatively build a magnetic loop for indoor use that I can tune up on 30m.

I dug out an old PC today so I could run WSPR and already I'm hooked.

Just watching those callsigns roll in on 30m is addictive.

Now I need to figure out a serial port to PTT interface and I can see how far my signal will go.

This is magic.

Hi all,

started using this nice piece of software this afternoon. On 40 mtrs they heard my QRP 8 watts in VK land, on 30 mtrs both me and K1JT heard each other. Not bad for an OCF wire dipole.

Nice Mode, immediately successful with FT-817, some wire and homemade audiocoupler. Decoded ZL on 30!

Hi all. I have been using WSPR for a few days now, and find it really interesting. So I built a VOX interface for my FT-817 and an old laptop so I can leave it on whenever i'm at home. One problem I had was the time not being accurate enough on my laptop, it could be 5 seconds out after 24 hours use, so I have set windows to update with a time server every 1 hour. It is not possible to do this without editing the registry.

I have wrote a quick PDF showing the steps needed to make it update once an hour etc:

For some reason I have never been able to run multiple wspr programs, but now it works. Using WinXP and internal + usb soundcards. Passed 24 hrs test now. See the attached screen pictures.

Will leave the radio on tonight set to 0.5w on 10 MHz. Will try using the home made 1/4 wave vertical and see if I can make it over the pond :-)

Just starting out. Been active with WSJT for a long time. Now trying WSPR.

Currently running on 6m with 5 element beam pointed East.

I've been trying to get the WSPR software to compile under Ubuntu 9.04, but am having no success at all :(

I am now searching for a set of binaries to download but so far have found none.
I am beginning to wonder if I am the only person trying to run WSPR under Ubuntu these days ?

i am qrv many bands,80M, with Windom antenna 42m long
40M with 2 elem Beam by PKW
10, 15, 20M TH5DX, and 6M 5 elem by I0JXX
and QTF is many time to 300 degré
