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.

Please note 80m frequency change to 3.5686 MHz (USB)

Please note, the WSPRNet site has been updated to reflect the change to the 80m WSPR frequency which is now 3.568600 MHz USB.

Thank you to K1JT and G4ZFQ for pointing this out.

[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.

Now trying out a home brew mag loop based on the G4ILO Wonder Loop.

Hi.
I just released my new WSPR Desktop transmitter.
It is an open source Arduino based transmitter just like the previous one.
This one comes built in a box with four low pass filters and covers either 137kHz-3,8MHz or 7-18MHz or 21-50MHz depending on what model you order.

Configured from a PC software but will operate standalone using it's built in GPS for time keeping and position.
Powered from 5V USB so it suitable both for the shack and on the road or hike.

Like many other WSPR'ers I have gone SDR. Recent 3 band spots have been from a KiwiSDR , a nice tool.
But from now on (5th November 2018) the RX is a Red Pitaya board running Pavel Demin's exceptional software on eight bands LF and up, I will continue using my 50cm. E field antenna which works very well and is almost invisible. Pavel has been very kind in assisting me over a silly set up error that came from You Tube!

I have been experimenting with my airspyHF+ for a couple of weeks now. It is a very nice device and I have been using gqrx on my linux laptop to view the entire 20m band, listen to QSOs, CW contacts and beacons. I've also used it to identify a few sources of strong QRM in my house.

Our URE LEGANES fellow EB4CUV, is doing an OFF ROAD trip.
Accompanied by QRP-LAB beacon U3 and MFJ antenne run on WSPR 30m every day, wiht very good reports.

On my systems, I got rid of that annoying "Development Purposes Only" message on the Maps produced on this website.

So, I use an Ad Blocker with Firefox. Yes, it's called AdBlock Plus. I don't use the latest "upgraded" FireFox, as it appears that the Crack FireFox Team destroyed all of FireFox's AddOn capability (which is what AdBlock Plus apparently is...). I don't know if there is a new version of AddBlock Plus that works with the new FireFox clunkware.

I'm pretty new here, and have been amazed at how many contacts I've already been able to log.
But even more exciting than the number of contacts is the variety of them: I regularly get
contacts from Japan, Antarctica, Hawaii, New Zealand and even the Cook Islands, all on 5 watts. Wow.

I added a new 7-day km/Watt transmitter rankings list to the top of the km/Watt pages.

http://mardie4.100webspace.net/wspr_grids/kmwatt-17m.html

On 17m, DL6NL has the highest total (almost 3 times as much as the next highest station).

The rankings are based on the last 7 days of wspr reports and add all the km/Watt values of the unique reporters hearing the transmitting station each day.

Rare Haiti station on 160m wspr heard by all Europe:

Just got one set up for WSPR reporting, will set another up for public access soon.
