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.

My kit from QRP Labs is now complete but I just can't seem to squeeze enough RF out of it to reach beyond the confines of my village. !!! The antenna is a 6 band Hexbeam and is currently WSPRing with a TS990S @ 5w as the driving force. Back to the drawing board with the QRP Labs kit. :-(

As many of you know, I've been doing a pretty lousy job at keeping up with WSPRnet site maintenance because of life and job priorities. I keep meaning to do better, but it's time to get some help! I know there have been people offering to volunteer at various times, but I figured I would just put out a fresh request for help.

Initial test complete. Was heard out to 1600 km with 1 watt out....
Will work on putting out more radials in the coming weeks

Will be testing my new 160/80 meters vertical with elevated radials tonight (17/18 April) from 2300 - 0200 UTC

Hello and thanks for reading.

Perhaps this has already been addressed, apologies if I missed it. We have Wspr-2 which I find covers most requirements from 630-10m. There is also Wspr-15, I have tried it too. Also there are other modes for MS etc. All great.

I know there are other data modes developed for VHF and above. But as far as I know - I am quite dim at times - nothing specifically for VHF in the Wspr pallet. The kind of thing I would envisage is a wider band shorter burst version of, say, 30 seconds.

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

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.
