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.

Tomorrow, I will be making a change which will redirect all access to the wsprnet community drupal web site (this site) from wsprnet.org to www.wsprnet.org. You may need to login again to create a new session. This is in preparation to move the interactive user site to another server to improve performance and separate that functionality from spot reporting.

Site changes for new WSPR FST4W modes

Since around version 2.1.1 wsjt-x has been uploading a `mode` value that WSPRNet has not been consuming. With the advent of new FST4W quasi-beacon modes we will now consume that value.

Going forward we will process the `mode` according to 4 values:

  • "2"
  • "15" for the current WSPR modes -2 & -15
  • "5
  • "30" for the FST4W modes 300 & 1800

This change applies to the manual upload too, i.e. WSPRNet will support an 11th column `mode` which can be one of these above 4 values.

[From Admins] Map issue -- a fix of sorts

The issue with the Google Maps is related to the change Google made on July 16th, 2018 that severely curtails the free API limits. WSPRNet will be transitioning to an alternative mapping solution as soon as possible.

In the interim I have added a new field to the User Profile form for storing your own Google Maps API Key, if you want to get back to the way things were. You can get your own API Key by following the link below and I would strongly encourage you to read the Q&A down the page.

Gutters were replaced. New gutter system has very high SWR. Now using an EFHW 17M wire antenna with 49:1 UNUN. Setup as a sloper from ground to pine tree in a west to east orientation.

Enjoying the challenges of QRP with FT8 and WSPR on my Xiegi G1M, no voice contacts so far but enjoying learning about proagation and my antenna

Here in eastern Australia, we have been having a great time today on 6m WSPR, thanks to JH1GYE and HL3AMO.

Thanks very much for the WSPR signals guys.

I'd encourage more operators in the area to give it a go.

Hello to everybody,

it was some months that I was not using WSPR because at the beginning of this year my Zachtek device has been lost during a courier transportation, it was in a storage center in Sweden when it has been lost.

Yesterday I tested out my QDX Transceiver running wspr on 20 meters.
I am using WSJTX software on my old Asus laptop.
My output power is about 4 watts into a half-wave dipole at 10 feet on the back patio.
I was surprised to see that my signal was heard in Antartica! :)

Hello OM,

Welcome to visit my blog. My name is Henry.

I am a truly Ham Radio Fan in Taiwan.

I like the homebrew antenna very much, under the page the antennas are all made by myself.

KD2OM, KP4MD and N6GN are now transmitting FST4W-300 on 14 MHz, GPS frequency locked to observe ionospheric spectral spreading.
Read FST4W on the HF Bands: Why - What to expect: http://wsprdaemon.org/ewExternalFiles/FST4W_on_HF_bands_V1-3.pdf
A greater use of FST4W on the HF bands could bring several benefits, the marginal sensitivity increase of 1.4 dB over WSPR for the 120-second variant probably being the least valuable. Other potential benefits are greater tolerance to Doppler spread and the significant increases in sensitivity from the longer sequences. While ionospheric Doppler spread will limit the use of the longer sequences, maximum utility of FST4W can come from careful attention to minimising spectral spread within transmitters and receivers. These are areas where the amateur can make improvements. As the protocol measures spectral width it provides the essential tool to both gauge equipment performance and also bring insights into propagation that SNR alone does not provide.

I change my mind again. Now I am using an end fed 125' to a 49/1 so I can beacon 80-15 meter bands. I don't want to use a tuner if i can avoid it. 1/5th of a watt; I don't want to waste any of it in coils. Having a hoot of a time on 30 meters.
