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.

The attached screenshot shows a series of nighttime spots between the UK and Denmark. I often see similar runs but to different Scandinavian locations. They are always very specific paths. My theory is that they are the result of E layer propagation from the northern wall of the mid latitude trough. This dips south in slightly disturbed conditions. Is that a likely explanation?

I have just completed the very simple installation of the new Sotabeams WSPRLite. Currently on 20m but conditions are pretty abysmal. Usual antenna in use (6 Band Hexbeam at only 20ft.)
Looking forward to doing some comparison tests with other antennas and beaming in different directions.

It's really nice to see so much activity on 160m.
This night we reached a new record with 796 dx spots "across the pond" just 10 days after previous one (784 dxspots Nov13/2016).
39 stations in the round (27 EU/10 NA)
10 NA stations heard in EU: K3RWR- K9AN- K9ANF- K9PAW- KD6RF- W1IR- W8AC- KK1D
3 EU stations heard in NA: DF2JP- DL3GAK- EA1FBU
To note George K9PAW heard by 14 EU stations, George running 1w, yes 1w !! and spotted by DL3GAK snr -14 (06:12z)

Good activity this night with 328 dx spots "across the pond" with 30 stations in the round (10NA/20EU).
10 NA stations heard in EU: AB4DF- K9AN- K9PAW- KD6RF- N2HMM- N9EMC- VE1SKY- W1IR- W8AC- W8OZZ
Curiously a one way propagation; no EU heard in NA !!
Best Rx stations: F59706(7NA), PA3FYM(6NA), SC0TID(6NA), G0LUJ/1(4NA), G0KTN(3NA), DL1GCD(3NA), DL1AS(3NA)
To note 3 "new one" heard for me (AB4DF, N2HMM, N9EMC) and a new count for my NA rx Challenge: 36 (21 in Nov2015)
We are now entering in the best period... so good luck !

Maybe our (small) WSPR community already knows, but SWL Patrick F59706
from France challenges/d himself over the last years: Trying to decode
as much unique US/NA callsigns on 160m (1.8 MHz).

Innocent readers may think: "Why?"

From my perspective, trying to belong to the top world 160m contesters
etc. etc., my answer is simple: "Yes, this is really a challenge."

It's a challenge against (man made) noise and a challenge to
improve SNR receiver/-ing performance on Top Band (160m).

Most spots come from europe, the USA and VK/ZL.

Not much from the "millions" of African countries, or the biggest land mass called Russia.

Or even the electronics capitals of the world, Japan and China.

What up with the rest of the world ??

I like try QSO in MF Opera / JT9 mode

Ive just returned to WSPR after 4 or so years. Im currently using a TS590 on a Cobweb antenna @10m for bands 10-20m and a 40m dipole @ 6m high.
Im looking to build an interface to allow my Clansman to use WSPR as it is a USB only HF radio. Perfect for the job!
If anyone has made a Vox for such a job, please send me an email.

Hi all wsprions,
You may find photos of the my latest project here:
https://groups.yahoo.com/neo/groups/redpitaya/photos/photostream

and there is also a manual in the files section of that group.

I will soon make a corrected version of the PCB and put it for sharing on OSH Park.

Se also attached documents. (The footprint is largely the same as the RP Zero, a Zero is hiding underneath one of the units)

Happy wspring!

Hi folks

We have developed a way of testing antennas using WSPR. It consists of a special WSPR transmitter (WSPRlite) and a website (www.DXplorer.net).

The website is available for anyone to use - you don't need a WSPRlite. It works well on a phone, tablet or desktop. It's a neat and unique way of looking at WSPR data. If you have a beacon running on 160-20 m give it a try with your own callsign. www.DXplorer.net

There are now several WSPR users who run multiple stations with perhaps different receive antennae. The WSPR map shows all of the signals for all of the stations but the callsigns are all piled onto the same location so it is not possible to see all of the worked stations, only the top named one.

Does anyone know about rx2oj being active on 80m from IA40
Can't see call on qrz.com

Hallo everybody !
I´m new here and have the following question:

Have an allmost unused contest-style-station.
For usage in wasted time of unusing think about WSPR should be installed there and work.

Now need some suggestions what to do:
Use WSPR-2 or WSPR-15 ?
Think to use 20 or 40W out for a time of 2 or 4 weeks.

What do you think ?

Very long wanted to build a beacon, many have tried and now I was able to make a fully self-contained beacon. The basis is taken MCU Atmega 328 + DS3231 + SI5351 + PA-1 ВS170. Beacon worked for over a month and during that time had the following results:
CX2ABP - 16673km
DP0GVN - 16160km
RI1ANR - 15508km
and others...

Building installation and start-up: Evgeny Zaryanov (UB0AGX)
Software: Alexander Sholohov (RA9YER)
Other assistance: Igor Lavrinenkov (R2AJA)

New record activity with 784 dx spots "across the pond" (previous 760 dxspots nov29-2013).
45 stations in the round.
8 NA stations heard in EU: K3RWR- K4RCG- K9AN- KD6RF- N1DAY- N2HMM- W1CDO- W8AC
4 EU stations heard in NA: G0BLB- G3RCE- G8DYK- M6VPW. Curiously only G station !

Best Rx stations: G8DYK(8NA), PA3FYM(8NA), G8HUH(6NA), KK1D(5EU), SC0TID(5NA), EA1FAQ(4NA).
