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.

Running an experiment at least through tonight. I'm running 1 watt to a 40m Hamstick at 6 feet on a tripod, with 3 15 foot radials under it. Running WSPR2.12 and a Softrock SDR using HDSDR.

WSJTX 1.7 installation appears to work fine on RPi2B with Ubuntu 16.04, a bit slow on JT65 decodes, but to be expected, I used image with ssh installed so could avoid using connected monitor and keyboard. Then installed VNC and gnome so can use remote GUI for access. Only problem so far is incorrect keyboard mapping when trying to fill in callsign and locator text boxes. Got round it by cutting and pasting from terminal window. This would be a big problem for a chatty protocol like psk31, but not for the minimal text jt protocols.

Using WSPR TX Shield.

Software: and Raspbian Jessie

If it keeps crashing after a few times, read

Works well.

Try sudo wspr -s -o -p -4.5 callsign locator -r 20 20m 0

Txs every other.

I'd ignored this mode previously, but then, I'd been at a QTH where antennas were possible. Now in a first floor flat I'm just amazed at how far 1 watt will go from a random length of wire stuck in the window, fed against the radiator pipes via an ATU. What a mode.

Well I have been working on a Bitx40 TRX for around 2 months now on and off. Well mostly off to be honest.
When I got it,it would not transmit. Two faults I found. One was my doing as I didn't understand that the PA had a separate power supply rail but the second one was a poor solder joint on the bias pot. So soon had it working but only 2 watts and not as stated 7 watts.

Currently running only 5mw on 40m and am amazed at how far away the signals are being received.
The antenna is an MFJ magnetic loop at just 2 metres above ground level. SotaBeams WSPRLite is the moving force (or should I say "whisper"?).
I will keep on 40m for a day or so longer and then see what happens on 20m.

Testing an FT-991 5w with EndFed Monoband Wire antenna 20m @ 15t

That is the "advice" given to me by older "wiser" UK Radio Amateurs. It's all ground-wave - no good for DX during a sun-spot minimum, they say. At a local Amateur Radio club, the members turned their nose-up at a suggestion of a local 10 metre net. "It will not work, people are too far apart, better off to use VHF", they complained. And therein seems to lie a pathological dismissal, and almost hatred, of 28MHz in the UK. WSPR has proven them very, very, wrong!


I am building Ultimate 3S kit and testing it along the way. Some pictures of the build

In the maritime world, AIS is used to track vessels. This is the first time that WSPR is being used to track a vessel as it transits Canada from east to west via the Northwest Passage in 150 days to celebrate Canada's 150th birthday. We managed to create a "confederation" without a civil war or overthrowing the Crown (we are so polite, eh). The Queen of England is also the Queen of Canada. AIS is very similar to APRS and has VHF and satellite components. You can track the Polar Prince using marine AIS as well as WSPR.

Started new antennatest yesterday to investigate the difference on horisontal and vertical dipoles on 14 MHz .

So far the vertical might have a small advance.

OZ1BPZ is using the vertical and 5P1CC is on the horisontal.

Sorry, all spots from PA7MDJ between 2017/06/04 2230 UTC and 2017/06/05 0012 UTC have the wrong band reported. The band reported is 20m, it should have been 40m.

Sri, all spots oz/dl4vm from 30/05/2017 16:04 utc to 04/06/2017 4:44 utc had the wrong locator.

Just started with WSPR using a WSPRlite running 200mw on 14Mhz from Scotland. I'm pretty much amazed at the range that is achievable running this tiny box and less power than a cellphone. First station in the USA has appeared in the log overnight.

Dear friends! Got the first in my life QSL card from swl13562. For 1 year of hobby in the WSPR theme was much, but it was a very pleasant surprise in the envelope! Many thanks to Ruud NL13562. 73 !!!
