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.

This is episode 5 in the Ultra Portable Digital Comms series and naturallu, it relates to WSPR. In this video we are setting up WSJT-X to run a bidirectional, man-portable WSPR beacon test kit. I've used WSJT-X, a Yaesu FT-817ND, and the ZLP MiniProSC, setting it all up on Ubuntu Linux.

the link

is my web site where my MEPT based on arduino and si5351 is detailed.

the .ino files for both FSKCW QRSS and WSPR can be found using the Github link at top right of web site.

I have yet to file the RF section of the MEPT but the block diagram of digital section is given.

I hope this proves to be of interest.



The v1.0 of WIZPit is now made open for sharing.

A link to its documentation is made available from:

Big congratulations to the stations involved with the trans-Pacific 6m Opening yesterday. Well done guys. This kind of opening is looked for by numerous operators every day so its good for some of the guys to finally get a great reward for their efforts.
As we are aware, WSPR was the only mode where paths were made, which goes to show the effectiveness of WSPR to identify these types of path openings, particularly on bands like 6m where openings can be very sporadic.

Running 1 watt from my Icom IC-7300 into a Full Wave Horizontal Loop at 30 feet.

Today had a first use of my WSPRlite transmitter using the antenna of PI9KLM on 40m and saw the first spots appear.
I am very happy to see it really works!

I noticed this on the Brendan Quest 2M Trans-Atlantic Attempt page on Facebook today. Maybe some others may like to try getting some signals in to VO1FN receive site.


I notice on the WSPR.ORG site there is quite a bit of activity on 2M....also the listening freq for WSPR is 144.489 which is the freq the VO1FN receiver is always on! Usually have the receiver set for 1500Hz audio offset. 144.489+1500=144.490500 --- I changed the mode today to WSPR-2 in WSJT-X and will leave it there for a while .

The antennas are pointing 60deg to Europe.

Haven't gotten out to Europe yet, but I have reached southern Brazil and West Australia.

Using this:

Ive joined WSPRnet to analyzer my new antennas. I have been licensed nearly 40 yrs. After 8 years away from the hobby I returned in 2013. Finally, 17 years after I poured the concrete for my big tower I purchased

We issued a new version of the WSPRlite config app today. This corrects a bug in our random frequency assignment algorithm.

We have also issued the Config app source code for third party developers.

Hi All,

I'm driving from Perth (Western Australia) to Adelaide (South Australia) and along the way I am setting up four WSPR transmitters with the following details:

I've had a Soft66LC4 for ages and never really used it for anything. Currently using it with a magnetic loop. Will see if I can get it to work.

Running the RPi3 with the TAPR shield filter board. Using my BigIR antenna. Looks like it is working very well!
Anyone else running the same set-up?

For those times when you're without access to network time or a GPS unit.......

This small program allows you to listen to the radio, click a button when you hear other’s start to transmit, and zero your PC or Laptop’s clock to the nearest minute or even-minute. This procedure usually gets you close enough to start decoding and making contacts.

You may find that you can get closer to “real” zero by clicking a second or 2 early on the next go-around, as it seems that most transmissions start a bit after the minute.

Running a Red Pitaya as WSPR transceiver since 9th of Jan 2017.
