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.

Currently running MFJ-1786 Magloop and Ultimate QRSS 3 indoors at ground level 200mw all on Lipo Batteries

Tonight I put WSPR to use in what seemed like a success. I transmitted on both 30M and 40M at 1 watt to determine the propagation for those bands. 30M was performing much better for me than 40M. I jumped over to JT65 and although 40 is my "go to" (I have a 40M dipole) I trusted what I had just learned from WSPR. Europe looked promising and although I tend to not respond to CQ's from Europe I responded to EU3AA in Belarus. He was working another station but evidently saw me and came back after the previous QSO was complete. Victor, EU3AA is now my personal best thanks to WSPR.

June 21, first day of summer. It’s the right time to sum-up my 2015-2016 Rx Challenge and my fifth seasons on 160m wspr.
This season was for the first time very extended and active giving my new record number of North American stations heard: 61 unique calls (previous 36).
Congrats to the eight stations running QRPp, to all usual stations of previous seasons and to George K9PAW my emblematic NA 160m station.

I am an SWL in the Denver area. I am currently running WSPR on two receivers with two different antennas in order to compare the antennas. My plan is to run them together in bandhopping mode for some number of days and then download the database and do processing on it.

K0SWL53 is an ELAD FDM-S2 with a 17 foot ground mounted broadband vertical. K0SWL54 is an AFEDRI Net 3.0 connected to an ALA-1530LNP loop antenna that is oriented east-west. My location is suburban. I am running WSJT-X and SDR-Console V2.3 for the software.

Now using a new Cobwebb antenna for 20 to 6 m's and have purchased a 10db attenuator for my Yaesu FT-897D and works a treat.

Nice to try , easy and working like a charm . A nice standalone WSPR receiver and automatic reporting to WSPRnet.

No more need of a dedicated PC and transceiver.

I did the setup , in 15 min.

It's thundery here. I've pulled the wire antenna down, and it's now draped over some outhouses.

I'm running WSPR in RX only mode on 10m, and I'm hearing all over europe. OH5XO and LA2BCN in particular, are really strong into my shed roof wire!

Hello all,

I want to inform you we will be sailing the Turkish waters & Greek waters (using SV5/) between the harbour of 'Datca' & Greek island of Symi using QRP-Labs Ultimate U3S with 200 ~ 300 mW & 2x EndFed slooper wire antennas for 40/20/10M & 30/17/12M! Also phone operations depending on conditions (mostly 20M & 17M :-) !) See for TA4/PH2M (SV5/PH2M) & TA4/PA3GUV (SV5/PA3GUV) information!

I ported my previous project to RTL-SDR devices.
Now you can use an RTL dongle with a Raspberry Pi, and you no longer need to dedicate your radio and your computer to run the classic WSPR client (this project is primary designed for VHF/UHF bands).

I have been using NMEA Time, D4 and Meinberg for many years. Starting 6/5/2016, my main computer all of a sudden stopped syncing time with all of them, even Windows Time sync won't work. My alternate computer is set up the same and started to show the same effects on 6/10/2016. Both running W7 64 bit and no know viruses. No new program installs or updates since the end of May.

Just wondering if anyone else has the same issue and how you resolved it, it you did. Kind of hard to get my WSPR station back on the air until I do resolve the pesky issue.

Tnx de N3EDS

I would like to introduce the new WSPRnet Admin team of volunteers to help me maintain this site and it's user accounts:

I do keep a blog:

My good friend Jan PA3GUV is now 'QRV' with Extended-WSPR from southwestern Turkey as TA4/PA3GUV from KM46HU, using a QRP-Labs Ultimate3S + 3-band EndFed wire antenna on 40, 20 & 10M WSPR-TX with +/- 200 mW! (Next week (from 12 June) we will be QRV from sailing vessel GanGan using callsigns: TA4/PA3GUV & TA4/PH2M from Turkish waters & SV5/PA3GUV & SV5/PH2M from Greek waters around the Greek Island of Symi!)

I do have a blog that I update now and then .. still have lots to update from Dayton! :-)

I'm pleased to announce the first official release of airspy-wsprd:
