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.

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.

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).

A new great session on 160m, 223 dx spots "across the pond", 20 stations in the round, 12 EU stations heard in NA, 8 NA stations heard in EU.
Best rx in EU, John (G8DYK), 6 NA stations
Best rx in NA, Carl (N2NOM), 8 EU stations

Personally i heard a new NA callsign (WA3DSP) bringing the count of my NA Challenge list to 22.
I am confident that will continue.

Ah, the old trusty FT840 is humming again. This time I'm camped on 1.8366. Lots of 9-landers. They must all have big back yards in Illinois for those big 160 antennas.

Added some new WSPR stats to my website. It is similar to the RBN section and has some advantages over the top wspr spots/spotters stats which are only updated monthly. The new WSPR stats section provides daily stats for all stations (tx/rx, SWL, or tx-only), uses full callsigns (multiple /'s, dashes, and underscores), handles 4 or 6-digit grid squares, and adds the power level (dBm) to transmit stations.

Look for "WSPR Spots stats" near the bottom of the webpage at
