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.

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 FTS4W 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.

For the last year I have been running a Wellbrook ALA100LN preamplifier driven from a 8m x 2m wire loop for LF to 6m. Because I am close to a MW broadcaster 9 pole HPF and 9 pole LPF are used to remove the 0.55-1.6 MHz signals ( 1/2 V rms antenna output !! ).

Many experimental report for antennas and other electronics devises in my blog. All are written in Japanese originally but may possible to see using Google translate.

Presently back on sloping 40m. loop @7m.

See the description and how to access this free program my the General forum posting. Search on wsprpath. - AJ8S

My first time on the wspr in a few years. I started at 5 watts and updated to 100 watts will run about an hour today

As the September Equinox is on the 22nd, it might be a good idea to get the yagis facing those on the other side of the equator. Probably a slim chance, but you never know with WSPR.
I'll have my yagi beaming in the European direction during my afternoons at least over the coming week.

Remember to check into the 50 MHz WSPR Group page on Facebook and let us know what your up to on 6m WSPR.

Currently experimenting and comparing a 1/4 wave 40 mtr. fishing pole vertical with two tuned radials abt. 60cm off the ground against the usual full wave 40 mtr. horizontal sloping loop antenna at 8 mtrs high.

New QTH Panama City Beach..
Grid EM70ag another HOA restricted property, BUT this one is a Villa with 2 stories and a frame house with an ATTIC ! There now lives my 2 mag loops a MFJ 1788 & an AEA ISO-LOOP along with a bent and folded (crumpled) doublet... I can tune and operate 6-40 an Air Conditioned room with solid wi-fi.. so nice compared to the last QTH.

Still using the Icom 706 and 703... new addition is a NEW Yaesu FT 891. having fun getting re-acquainted with the hobby..
