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.

WSPRnet is a thriving community with great people who are engaged and passionate about WSPR and it's use as a propagation tool. supports users blogs to enable people to share their experiences and experiments. Both because of the workload it would require and the bottleneck it would represent, we don't moderate blog posts. This means that its a great way for forum spammers to post their graffiti all over the site if they were to get in.

I am finally active on 630m using my new part 5 callsign WH2XNA. I am starting with my Ultimate3 kit running barefoot. Estimated ERP is 10mW and I am only able to transmit.

Thanks to N6KOG for being my first spot (ground wave I presume):

I've turned on my WSPR beacon on 80m tonight November 28th.
Power is 3W into a low above ground OCF dipole.

Hi everyone,

The first WSPR TX App for Android is available in the Google Store.

The WSPR Beacon App is made to send WSPR signals using your Android smartphone/tablet as a signal source. All you have to do is couple the audio out with the audio in of your rig (and set it to VOX).

All you have to do is:

I've put a beacon up using the ultimate3 kit with a Ublox7 GPS to condition the frequency.
All seems to work ok into a low down windom.

I've set it to 14.097.165 , good strong satellite fix so that should be right.

I'm now not sure how accurate it is though - the spots so far show a huge amount of variation.

I guess I could be right and everyone else wrong!

QRV with Raspberry PI headless w/o LPF on 20m. Just a long wire in GPIO as antenna. Let me know if anyone RX me.


Thanks to the hundreds of people who have downloaded my WsprNet Viewer program from the Google/Android play store:
The next iteration will include Google maps capability to display great circle propagation, markers, and beacon heat maps. See some screen shots (using Chrome or Internet Explorer) here:

I've managed to get my attic based WSPR PI beacon back online, still just QRV on 30m but if all goes well I should soon be adding some more bands.

Increasing the number of US stations received in JN06CI:

Interesting active night and sunrise on 160m, around 150 dx spots "across the pond", 6 NA stations in the round (K9AN, N3CO, KC2STA, KB1YFS, W1FVB, N2NOM) and 9 EU stations.
To note the long session between KB1YFD and me (38 spots), the same snr level(+/-1) along the night with an early spot:
2014-11-22 23:10 KB1YFD 1.838011 -23 0 FN41ro 10 F59706 JN07th 5555
and the last one at 07:18z.

Thank you to all, Patrick

I have been running two crossed active loops for well over a month now as well as the e-field active that has been up for about 10 years. Living with several antennae is always interesting, the ability to instantly compare always useful. For WSPRing all have virtues, the very broad e-field is always there as a reference of known sensitivity while the directive loops are quieter on the low bands. For size, very low cost and stealth the loops are very hard to beat, they also seem to receive at least as well as a top loaded Marconi on low bands.

Version 1.0.0 of this app is now published on the Google Play Store.

Search there with 'WSPR'

This app plots real-time transmission paths on a world map which may be centered either on the Atlantic or the Pacific. It includes a background display of the 'greyline' or terminator.

Paths for a single station may optionally be displayed with callsigns.

It is highly recommended that you read the FAQ to get the full benefit of the features in this app.

Very many thanks to the testers of this app who have given me much valuable advice.

Not one decode on 160M the last 24 hours.. Taking to rig to work tomorrow to put on the IFR. I think band-relay shot.

Hi all

I have just bought a new Yaesu FT-817 . I am going to use it on 500mW most of the time.
Power :- 500mW
Antenna - Windon CWS-80 TheRadioWorks.

Have recently tried a couple of weekend tests on 160M, still using the same setup, but tuning the Ant system with a MFJ tuner to get a 1:1 Match at the TX, certainly hearing wise,the system seems to work well, but reports back on my transmission certainly show up the in-efficieny of the HF9V as a 160M Ant, without the 160M coil for it? if I hear 20 stations, as a return I am probably only reported by 4 or 5 in return!! May look at purchasing a 160M coil for the HF9V, although its a compromise antenna at best, cannot get anything taller or long out.

I'm now qrv wth My Ultimate3 wspr unit. I'm transmitting on 28.126.100, and now hoping for some reports
Vy 73 de OZ1BEE

A real surprise on 160m, between 05:02Z and 06:46Z (EU sunrise), not less than 67 DX spots "across the pond"; 40 from EU and 27 from NA. In the party were: K4MOG, KJ4YBS, N2NOM, WU2M, G0KTN, G8HUH, G3VIR, G4FKK, G4BOO, F59706.
We note a probable new qrpp record (EU to NA) with 200mw (congrats to Martin and Rocco):
2014-11-10 06:38 G4FKK 1.838027 -26 0 IO91wi 0.2 WU2M FN23tb 5440 291
For my part, I was able to decode two new stations (K4MOG, WU2M), bringing my score of my RX challenge to 17 (close to my 19 of last year at the same time.

Fingerss crossed for my first spot! :)


Following a storm my 30m WSPR beacon is offline, I'm hoping to get it back up and running this week.

Also considering adding another band to it, perhaps 10m.

Has anyone thought of a new WSPR freq in the recently allocated UK (by NoV) in the 146-147MHz band? (Use it or loose it am thinking). I am experimenting using WSPR on DIAL freq of 146.9000MHz (Tx on 146.9015MHz). However, I found WSPRnet will not show this frequency in either the 'Activity' list, nor on the 2metre map.
