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)

Forums: 

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.

Dear Users,

We are going to take the site offline for a few minutes around 16:15 UTC, and make a change to the database that I hope alleviates the performance issues.

For the 24-28 hours the spot database will be missing older spots. I will repopulate it slowly, starting with today's spots.

Thanks for your patience.

Happy to celebrate passing the US general license exam last Saturday, 9 November, in Windsor, Colorado. It took some time to press the information into this aged grey matter but at last success. 73!

I found a nice QRP WSPR transmitter online from Zachtek.com and ordered the mid-range model that covers 17, 20, 30 and 40 meters. Output is a reasonable 200mW on all bands and I am running it into a converted vertical antenna over a few buried ground radials (I plan to add more radials soon) and am pretty pleased with the results. I have worked all four bands on and off the last couple of days and seem to get consistent results from Hawaii to the East Coast and up into Canada pretty reliably.

Somebody!? this is getting bad

AS YOU MIGHT KNOW I'm NEW TO WSPR.
CAN I USE THE RASCAL SOUNDCARD INTERFACE FOR WSPR ? I HAVE THE PK232MBX AND A PK88 AND THE AEA COMPUTER PATCH INTERFACE. I ALSO HAVE THE RASCAL AND A WESTMOUNTAIN RIGBLASTER' SO WHICH ONE SHOULD I USE FOR EASE OF OPERATION ? OH I HAVE USED THE RASCAL AND THE RIGBLASTER FOR SSTV ON MY IC-735.

I've been perusing the maps of my spots and over the last year or so, since I have been paying any attention to it, anyway, there is a definite lack of spots from here in the northerly direction. There could be a couple of different explanations for that, however. It is entirely possible that there are no other WSPR transmitters or receivers in the area over North and South Dakota and the empty spaces in that part of Canada.

N4HQS here... Putting this out there for a start of my blog.
Not sure what else to say right now. Feel free to reply with a hello.

While visiting friends out in the country, I noticed an old vertical antenna stacked with some plastic pipe and managed to talk them out of it. They were happy to get rid of another piece of scrap and I have a plan for t, already. Originally made for use on 11 meters, I realized it should be simple enough to convert it to work on 10 meters and maybe even tune it for 20 meters, so I began working on it. The mast itself had at some time been replaced with galvanized electrical conduit, which was corroded, so that will be removed and replaced with 3/4 inch copper pipe of the correct length.

Just re-checked the map and I have entries for the QRPGuys EZ WSPR-PI from Illinois, Alabama and Georgia!

Not bad for an estimated 80mw transmitter and an OCF dipole with no tuner.

So, I recently reworked my 'snake' antenna that is merely about 600 feet of two pair armored telephone cable. I terminated it by wrapping it onto the top wire of a barbed wire fence down by the road and drive it at 1 watt from a Yaesu FT-890 with an on board tuner. I didn't expect much, but am pleased that it produces better results than a handful of Hamstick verticals mounted on the house. Next, I'll probably try to use that wire on the ground to work FT4 and FT8. Nothing to lose, I guess.

Finished the WsprPi hat and added it to the Pi 3 B+. All seems to run OK, but nobody seems to receive the (100mw?) transmission. My local HF rig with a junk antenna heard it and it decoded ok in WSJT-x. Oh well, more troubleshooting to follow. I'll try 5w with my base and make sure that's working OK tonight.
