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.

160m season continues to provide new DXCC.
Following French Guiana (FY5KE) and US Virgin (KP2XX) United Arab Emirates was now heard for the first time on 160m wspr in Europe by some lucky stations, John(G8DYK) opened the way:

How to extract a logfile for a given call sign out of the huge Wsprnet historical database ? This was the brain exercise of the last week. And I was amazed to find that with a short program coded in python language the solution was easier and simpler than expected. My friend Ivo, IW1PAK was so excited of the result that convinced me to publish the program and explain it in the best understandable way for any one so that other WSPR users can play with it.
How does it work ?

My new home made SDR TRX with max 5W out is now online.
The TRX is made with the "Red Pitaya" Board and woks in WSPR very fine.
I will be bands from time to time.

After about 3 evenings of pain and tears trying to compile WSJT-X on an Odroid XU4 it is now up and running!

So this is now my RX-Setup:
- Mini-Whip antenna
- Kenwood TS480-SAT (remote controlled by WSJT-X!)
- Odroid XU4 running WSJT-X

Next goal: get SDRplay running with Odroid XU4 - that would be a nice and compact WSPR-RX combo... :-)


This summer I have been trying to get some activity on the two metre band. In the past I have not observed much activity in New Zealand but recently ZL2IT and ZL3PX have been on regularly, and exchanging reports. I have recently joined in, and another wsprer I have seen is ZL2COM. These station seperated by long distances, the shortest path I think is from ZL2COM to myself about 200 km.


We are currently working on a WSPR tracked buoy. These posts will be to share our progress with anyone, and keep a reference for us so we know what we did so we can create more.

I am a member of W1HLO, the Norwich Free Academy High School Amateur Radio club. One thing that our club likes to do is tracked beacons. We've launched three weather balloons, one of which was very successful and traveled from Norwich, CT to Canaan, VT. This year instead of a high altitude balloon we decided to build a buoy which we would release into the ocean and then track its position.

In the past I had an Elecraft K3 and was able to transmit and receive WSPR just fine! Now I have a new Elecraft K3S that I am unable to transmit a WSPR signal!
I have spoken to Elecraft and they can not help me with this problem. Can anyone help me with this problem?

Thank you for letting me join the community. I appreciate the opportunity to learn about WSPR and radio.

"...'My season' ends after next weekend (13/14 Feb) because the land owner needs his property, where my Beverages are located, for horses..."
Remco (PA3FYM) has announced the end of its season on 160m. I think he has marked his first and short season(Nov24/2015 -Feb14/2016) by his participation in the activity "across the pond".
Over this period he has decoded 33 North American stations with beverages for the RX Challenge.

13/02/2016 Finally persuaded the FDM-DUO (and FT-991) to work satisfactorily with WSJT-X (WSPR)so now band hopping running 5w to the Gap Titan antenna. Its been well worth the effort!

Active night on 160m : 669 dx spots "across the pond" in the data base, 38 stations in the round.
9 NA stations heard in EU: AB4DF, K1BFS, K4RCG/4, K9AN, K9PAW, KD6RF, KJ4YBS, N1NCO, W9MDO
Best Rx stn: KK1D(14EU), K4RCG/4(8EU), F59706(8NA), G8DYK(6NA), PA0O(6NA), G0KTN(5NA), G8LCO(5NA), ON4LUC(5NA)
To note a new one heard for me (K1BFS) and a new count for my NA rx Challenge: 47
