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.

Hot conditions last night on 160m: 539 dx spots "across the pond" in the data base, 25 stations in the round.
3 NA stations heard in EU: K9AN, WA3DSP, KY1R
8 EU stations heard in NA: DF2JP, G0LUJ, G3RIK, M0KWR, M6VPW, ON7KO, PA1RZ, SM6WZI
Best Rx stn: KK1D (8 EU), WY1R(6 EU), F59706 (3 NA), G8LCO (2 NA), M0KWR (2 NA), PA3FYM (2 NA).

hi every member I am new to wsprnet and wold like to say you will find me on 15/40

I admit all to often I will jump in to a new mode without reading the how to guide.

I thought I did that with WSPR but was stuck on hearing but not heard. The problem was that I was not centered on the 0 of the waterfall, once I doubled click on that spot I was being heard.

I followed the setup for SignaLink however I was not receiving or transmitting. The setup for Win 10 as follows:

WSPR Setup: Audio In: MME Microphone USB Codec, Audio Out: MME Speaker USB Codec.

Built and start TX on 5 bands
The average result after 2 days 30m >> 500-1500 km ( max 2600 км) 20m >>> 1000-2000km 15m>>>2000-2500 км 10m >> 2000-2500 km
There is no point in larger than 1 Watt the power in this mode otherwise explore the pleasures, except probably 80-160m

I will have to disassemble my station early 2016, since we are moving abroad. VK2GOM will go QRT, and will eventually become an 'available' callsign again when I don't renew my license in May.

I will attempt to re-activate my 30m WSPR beacon from the UK with my UK call, G0MOH.

Hi. Sold the house and moved to smaller appartement. Now I have only a 30 feet grounplane vertical with some radials and a JC-3 remote coupler at the base of the antenna. I can work from 80 to 6 meters with this combination. Exciter is a Kenwood TS-590SG and 5 watts.

I see this now, Chaos Tools AJAX Demo down the side of the main page ;-)

Ready once again in WSPRnet(ing). Since last night QRV on RX from LF to 6 Meters. Hope to configure some TX on 40 and 30 and 20 tomorrow.
I'm usign WSPR-X on a debian machine, the radio is a TS-590S connected to a vertical GP with a SGC-230 at feed point. I will try to run it unless I need it to make some QSO's :D

I don't think I have ever been able to update the Map, get on and off Chat, have a squizz at Activity and a look at the Database as rapidly as I am able to do at the moment 00:44 Friday 20151218. It's wonderful. Thank you. was down globally according to This seems to be a server bandwidth issue. Perhaps the spot database handling should be run on a separate server? I also get frequent failed data upload access attempts.

Has anyone else been having trouble accessing I have been experiencing problems for several weeks and it has gotten progressively worse recently. Very slow response or no response at all. Also noticed spot uploads failing more often.

I had experienced the same 2years ago (2013/12/21).
Good condition have lasted about 2hours.

Now operating for 5 weeks from Auckland as ZL1/G4YBU. Apologies for incorrect qra and call data accidentally sent. My program reverted to my home station info before I spotted the error, now corrected.

a minimal SDR receiver using only two chips from analog devices is now active 24/7 on 630m in JN68NT (DJ0ABR).
It contains a preselector (design:
followed by a AD8332 pre-amp and a AD8333 I/Q mixer.
Circuit diagram:

That continues with hot conditions last night on 160m, 417 dx spots "across the pond", 32 stations in the round, 17 EU stations heard in NA, 15 NA stations heard in EU.
Best rx in EU, John(G8DYK), 10 NA stations
Best rx in NA, Josh(KK1D), 5 EU stations
Best tx in EU, Andy(F6CNI), 12 NA stations
Best tx in NA, Doug(WA3DSP), 9 EU stations

I added two new callsigns to my NA RX Challenge list (N8YE, N1NCO).
