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.

I will occasionally submit heard spots now. I have an IC-9100 and want to see what I can hear on 20m and other bands.

Okay I think I posted the date wrong in that last blog post. Not March yet. See? I could use an editor. An editor with a shredder.

I have been keeping to the same schedule lately mostly 80 meters at night and I switch to 40 during the day. And occasionally I will make little forays into 30, 20 (mostly 20), and today I tried 15 meters for a while and got zero results. Then dropped down to 17 meters and I got one receive report on my signal! Hooray I was thrilled over that. I don't know where they were. I don't care where they were. I had a spot! Hooray! In my situation it is a victory let me tell you.

Hi all.
I just released an expansion card to my WSPR-TX_LP1 transmitter.
It expands the transmitter with four switched low pass filters.
With this combo the transmitter forms a standalone WSPR transmitter with on-board GPS that can do band hopping on four or more bands.
It is possible the lowest cost multiband WSPR transmitter available today. And it's Arduino based with open source.
I hope you find it interesting.

I wonder if it is possible to design a wspr qso mode that allows multiple stations to handle the communications, as in this sketch?

I have been watching 40 meters mostly on wspr mode. 40 can be really excellent at times. I jump to other bands once in a whole to compare. But always seem to come back to 40 meters.

Currently I am using a KiWi SDR for the WSPR project. I am trying to have a minimum of 3 decodes running 24/7 on the long wire antenna.
I am rotating trough the bands, VLF up to 10 Meters.

The API fix works fine. Google says when you enable billing, you get $200 free usage every month for Maps, Routes, or Places. Based on the millions of users using our APIs today, most of them can continue to use Google Maps Platform for free with this credit. Probably won't cost anyone a cent.

Tonight, I've looked for WSPR spots on LF, MF, 160M.
Strange spots I've seen.
Callsigns, powers, distances is fantastic!

Merry Christmas to all around the world !!

From WSPR 3.0 User’s Guide we know that computer clock must be correct to within about ±1 second.
I've tried to test it and find practicullar limits of error.
First PC is receiver, and have internet time sinchronisation.
Second PC is tranceiver and I setup clock as I want.

We can compare DT parameter on first PC, and get or get not spots from other WSPR world stations.
Band is 40M. Power is 0.5 W.

Accuracy clock manually setup is near one second.
