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.

Hello All,

Inspired by several websites, personal blogs and various presentations floating around the net, a couple of us WSPR users are considering an Open Source Project to provide a set of Local User Tools ( On / For Your PC ~ Win / *Nix / OSX ) to analyze data made available through the WSPRNet Archive Pages / OldDB / Local Data Collection.

We're looking for ideas as to what types of data correlation would be beneficial to end users. Items such as, but certainly not limited too ( all ideas welcome ):

Para contacto estaciones EA.

Very excited to get the new rig running after 24 hours of trying various settings. Because the Hamlib setup in WSJT-X does not have an option for the 7300 yet, a work-around is needed.
The final method I used was to change the default CI-V address to 88h...this makes the rig appear to be an IC-7100. Make sure you download the USB driver For your PC from the icom global site :-

Hi All

Have finally got WSPR online after some time. Primary setup is QRP labs WSPR kit 200mw output. Running into a random wire endfed. It cycles between 80 40 20 15 10.

Secondary setup is a WsprryPi. Running on 40mtrs only, its around 5mw by the time its gone through the filters and done its thing.

Thanks to all who have spotted already. Looking forward to further propagation experiments using both. Possibly a 2mtr / 70cm setup exploring the path across the VK bight


The beacon is now at JO77, outside Huskvarna, Sweden. Same equipment as earlier at JO66 in Falkenberg.

Hi all

Dave VE3KCL launched his S-9 balloon yesterday. It uses a QRP Labs QRSS/WSPR transmitter ( with about 16mW power output on 30m band, using WSPR for tracking. See for live map tracking, photos and more details. Dave's transmitter, antenna, batteries and solar cells weigh only 23g in total!

Installed a kitted-up Comtek coaxial cable feedline choke, replacing brand-X, and it completely solved the issue of 17/15 meter RF in the shack. So will be band hopping (20% xmit) on 80 through 10.... still working the 160 meter antenna.....


A short post to notice a new VHF beacon is in operation on 50.294 450MHz

VA2NQ beacon uses WSPR & PI4 protocols (2x PI4 & 1x WSPR, eg. 50% WSPR)

I was born in Belém do Pará in Brazil in 1947, where I graduated in civil engineering in 1971. Since his youth he was a passionate amateur radio in and after many years I achieved my target in 1978. My life is full of struggles and if I were to tell would a book. But I love doing radio since winning the award that all amateur like to have is the Top Honor Roll in the DXCC. It makes me very happy because I fought a lot to achieve this. Now I want to dedicate the expeditions more because I realize when together with other radio amateurs do a new island to air reaching all those in need.

Ive been watching my results on 80 meters on the WSPR Challenge site.

For two days now Ive been lucky enough to hit the number 1 position, but this has caused me to question how much of this is due to my home location being electrically quiet ? Or is it the RF performance of the SDR equipment I'm currently running.

One thing is a fact however and that's my 80 meter antenna which is a simple 66 foot wire could be significantly improved.

After weeks of listening, i've finally sorted out an interface between my FT817 and my laptop. Living in a top floor flat and not having much room, I decided to try a random wire at the lowest power setting the FT817 would do (500mW). This random wire is a few metres long and is tuned using an MFJ 941E.

I'm amazed at the results, for what i thought would be terrible antenna, with a record so far of west coast Australia (around 14000KM!).

I upgraded my equipment to a direct conversion SDR: the Genesis G3020. The rig, when coupled with a very affordable SYBA SD-AUD20101 USB audio card, performs very well. I'm still "only" listening; I have been having great success with WSPR on 30m. The Genesis, with this audio card, is far more sensitive than the upconverted RTL w/LNA.

I am currently hopping between 15, 17 and 20m with 10mW into
my 3 Element steppIr set for Bi-Directional use
dir 90 and 180°.
