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.

the two pass decoder is incredible and magical for weak signals, same freq. !!!:

Today UY0LL spotted me on 6 meter WSPR (2056 km).

I've been plugging away for several weeks now with no spots from IO74.

I've a raspberry pi with a 1/4 wave dipole and lpf transmitting on 14.0971. The dipole is in my roofspace and facing east/west. I know transmitter power will be an issue but I'm hoping for at least one spot before I go to the bother of making an rf amplifier.

I don't have a rig but I'm getting a good signal via my computer/sdr dongle 20-30m away from the raspberry pi transmitter.

If someone can point something at me or do some wspr receiving magic I would be very happy :-)

If my grid square is DM22 I am in Yuma, Az. If it is DN42, I am in Thayne, Wy. in the summer.

Travelling around NZ North island.
Icom 7300. Rt-11 remote atu. 5W into 35ft vertical on the motorhome ladder.
Some homebrew stuff coming soon.
Regards to all.

Today's tests are on 20 meters using an FT-817 @ 5 watts, a Galaxy Tab 3 tablet, WOLPHILink Interface, and an MFJ 1899T 'walkabout' antenna unning in a second floor bedroom. So far reports show reception from both sides of the USA and up into Canada. I've had decent luck with this minimal setup, making SSB and CW QRP contacts on a fairly regular basis.

If I can get the antenna tuned up nicely I'll probably switch to 30 meters this evening.

If possible please QSY 60 meter WSPR to dial frequency to 5.3647 MHz so the TX frequency is 5.3662 MHz.
We are than within the new IARU R1 HF bandplan.

Recently I tried an experiment, I went mobile on 70cm WSPR. I used an Icom IC706mkIIg that I have in the car along with a rubidium 10 MHz frequency reference and tripler to replace the Icom's 30 MHz master oscillator. I ran WSJT-X on an old laptop. The antenna I used was a dual-band vertically polarized whip so it was cross polarized to the signals from the N6GN home station beacon running WSPR, JT65A, JT9 and CW on ~432.301500.

Just testing Elecraft KX2 and WSPR, works fine, with 1 watt @ 30m up to 18.000km to ZL.

Hi – Currently WSPR’ing 144.4905 – running about 20w – beaming SE from IO84mv – Carlisle, Cumbria

This year's summer vacation is in Balatonfüred / Hungary (JN86wx). Our accomodation is about 100m over the lake with a great view to the south. I brought some antennas to test with me:
- a very simple GP for 40m / 15m just built by some wires and a 12m glass fibre mast
- a ZS6BKW (it's been the pile up cracker during our last holidays in croatia)

I'm going to play on 2m for a few hours. I'd be interested to know if anyone can hear me.

West Midlands, UK.

Using 10W to a collinear.

[edit 19:10 UTC]
Now band hopping 2m 144.489 -70cm 432.300

[20:10] QRT. there are three people in the world on 70cm WSPR, and I'm the only one in Europe!

if anyone fancies a try again, just let me know.
