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 am trying RX-only for a while, because I am trying k9an-wsprd on the Raspberry Pi 2. So far I am impressed, seeing up to 11 decodes per cycle and weak -27 db signals regularly. I haven't taken accurate measurements, but I estimate it takes 30 seconds to decode the WAV file.

Very odd spot this evening on 17m,

Which when plotted on the map says northern Iraq... Has ISIS started a propagation study?

2 Meter WSPR activity has been happening daily for years in the California area (and elsewhere!) and I was happy to be a part of that effort when I lived there in the Bay Area. You can read of their exploits, as well as other VHF and UHF WSPR activity here ----> https://groups.google.com/forum/#!forum/2-meter-wspr

Hi Guys! We now started on 50.294500 in Kyiv. KO50GK - Now using - U3S(Thanks Hans!!!) - ( U3s+GPS+OCXO) and GP. In next step - 5w+3el to Eastern Europe

Hi,

We have setup OY6FRA to run on 80m now and during the total solareclipse on the 20th
There will maybe aldo be a wspr running on 160m

Dear Guys,

let your rig running during eclipse at the morning of March, 20th 2015 . Hopefully we can detect effects.

Help to set up Kenwood ts 2000s and Signalink USBfor WSPR and other Digitalmodes.

Well, I wasn't into Ham Radio for a while, but the mood has struck again. So I'm back. Finally got WSPR and WSJT-X up and running. Having some fun.

So, at long last, I have finally installed WSPR and got it going!
Now trying to learn what it all means!

Fun, another new dimension of the hobby.

73 to all,

Time is critical running WSPR. For those operators in The Netherlands and surrounding countries here is a list of some Dutch NTP servers with low ping, which you can add and set as standard to your Windows internet time:

ntp1.nl.net
ntp2.nl.net
time.kpn.net

I am using the Ultimate3 kit with my Alex-loop in house.
I make 275 mWatt om 30 meter.
I get reports from a lot of stations in Europe but also the USA.
Great!!!

My longest DX to date:

2015-03-11 19:58 VK4XJB 28.126127 -23 -1 QG52xh 5 SWL-K-FN41 FN41jp 15825 57

Receiver setup:
- SDR# receiver software
- SDR dongle (RTL-SDR Blog Brand R820T2 RTL2832U)
- 10m horizontal dipole strung in attic
- RG-6 quad-shield feedline
- FM trap (Radio Shack 1500024)
- ferrites at USB and antenna inputs to SDR dongle, and at antenna feedpoint (Fair-rite 2631803802 1-300MHz 31 round cable core)

After some discussion it seems the Day/Night overlay on the Maps does in fact work . It still states "currently not working" however.

I was listening 630m all night long with some success:

G3XKR heard same stations but in a wider time range (03:04-05:28z).

73, Patrick

Just ordered a QRPLabs ULTIMATE3S kit. Only 20mtrs until payday. Hoping to order the relay and the LPF filter boards for 40,30,17 and 15Mtrs.Plus the GPS unit
I'll be running it all through my Hustler 6-BTV.
I've also ordered some more BF170's for the higher output.

Thinking too about using the VELLMANN voltage regulators to power the processor, GPS and the PA section (At a higher voltage,,,say,,,12v) I can then use a 13.8v PSU that is in the shack to run everything.

Testing with a scope on a dummy load I found my Ultimate3S has only been producing 20mW rather than the 100mW I was expecting. I added an extra transistor on the power amplifier but did not succeed in increasing the power. Now (back inside the house and) attached to the G5RV I only got one spot yesterday and one the day before (same station Jorgen OZ7IT in Denmark and roughly same time). I wonder if drift is also a problem? It should be OK as calibrated by GPS.

The last 2 months have been very active for WSPR. Excellent server uptime and improved signal decoding (K9AN decoder) have really helped the spot numbers grow.

January 2015 was the first time there was over 8 million spots for the month. January had 8,037,932 spots. Prior to that, the closest we came to 8 million was in March of 2014 which had 7,917,817 spots.

The service provider where this server is hosted has planned a scheduled downtime around 2015-03-08 1800Z. If all goes well, the outage will be brief, but I wanted to let everyone know.

I am using a 5m fishing pole antenna in the garden with three radials. The Ultimate3 and MJF manual tuner are in a waterproof laptop bag on my lawn. It should give me a more uniform radiation pattern than the horizontal dipole I was using before.
