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.

Starting the WSPR on 20m tonight at 19:58z, 2017.09.22... not much going on as I expected... I believe 20m is a band that can also open up at night, though less so than 30m, and much less so than 40m or 80m... I am assuming that 20m probably opens up more at night time during the colder winter months?? But I could be quite wrong about that...

Yesterday I worked WSPR (it worked, I slept) and I noticed that it was hugging the night trying to stay on the side of the light as the grey line moved, always trying to stay straight up the grey line and to the west, from my QTH up into Europe.

Just was bored, trying to get WSJTx up and working right on an older PC running Debian 9. Man, it is hard to love linux more than Windows, I hate to admit, when hunting down dependecies and, well, everything else! Had to use VOX on the PC since no idea yet how to get this cable with a Prolific Chip to be 'driven' yet under linux.

Between 19:30z Sept.20.2017 and 03:30z Sept.21.2017 (10:30PM Israeli time to 06:30AM Israel time, apx. 8hrs.) was the very first time ever in my life using WSPR. It was easy enough to get started after watching a short youtube video. I just left it running all night while I slept.

I let it run on 40m this first time because, to my limited understanding, 40m may very well be the most easy to predict, to notice patterns that usually repeat every day and night, for around what times propagation opens up this way or that, or when the band is closed.

Hi Gang - I'm currently monitoring 80 meters using my 8 element vertical receive array. I'll leave it pointed to the Northeast (Europe) from my sunset until about 09:30 UTC, when I'll switch the receive array to the west, before I leave for work.

I have an 8 element receive array for 160 meters also. We can try that next week.

After practically giving up on Sunday night, I gave it a second go yesterday afternoon and am so pleased persisted cause I cannot believe the results. Woke up to find my little shed had heard signals from Texas, Canada and, the icing on the proverbial cake, Southern Australia!!! This is obviously amazing but I can't help but wonder where do I go now, how can you top Australia? One thing's for certain, I'll be leaving the current set up just the way it is for a few more days yet, I'm positively hooked to the map, and will be investigating transmission next.

Must have spent four hours farting around with various receivers and frequency combinations yesterday evening without decoding a single transmission. Installed a programme to keep a check on the PC's clock this afternoon, mucked about with the Sangean's frequency and it's been gravy since. Bagged some stations from the far north of Finland and as far away as Bulgaria. Overjoyed to see we picked up a signal from as far south as Palma, our favourite holiday destination. Loving this, can't wait to start transmitting.

Was heard by EA8BFK today. My 5 watts into my attic dipole at only 15' apparently found a path. And prop conditions are poor. Nice.

See geographically illustrated summary of solar eclipse WSPR propagation on 160m and 630m. Over forty operators used 160m during eclipse. (scroll 1/3) Thanks, all.

At the moment I am in the Republic of Belarus. 50 km to the south of the city Vitebsk village Zavetnoye LOK: KO54DU. Here I have the equipment: FT-857D, ANT: CW80-100 40-6m, F9FT 9el on 2m. 73! See you live!

- Simultaneously 3 band Tx (40m, 30m and 20m)
- 3x200mW
- Automatic time syncronisation with GPS
- Power supply with 5V USB power bank or 7V-26V DC
- 50 ohm output can feed 3 band dipole antenna
- Robust output amplifier (e.g. will not be damaged due to static, ...)
- Wide temperature range

So, it's designed to take with you on holiday.

Use the radioberry (a trx radio hat for the Rpi) as a standalone multichannel (4) WSPR receiver.

The WSPRBerry implements the following:

-) recording max 4 WPSR channels

-) using FPGA firmware, implements a DDC to produce 375 samples per second

-) writing the samples per band to a .c2 files to process by the WSPR decoder

-) upload the decoded to wsprnet

Amazed that my 2 watts of rf to my 90cm diameter mag loop was heard by VK2XN at -16db.
I also heard VK2XN at -12db.
Does that count as a contact ;-))
More surprising because of recent radio blackout due to a CME the previous day!
