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.

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: http://www.spirat.com.au/vk5zvs/pic55.htm)
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).

GL all, 73, Patrick

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 http://mardie4.100webspace.net/

First 500 spots from database sorted according to distance:

First active dx night on 160m with around 280 dx spots "across the pond",
5 NA stations transmitting and heard by 4 EU stations.
9 EU stations transmitting and heard by 14 NA stations.
To note our friend Hamish (GM4SFW) heard by K2RH for his first "across" of the season.
I myself heard KD6RF, K9AN, K4LY and a new station K4MOG.
With this one i reach 21 unique NA callsigns heard for the new season of my RX Challenge(previous/same period:19)

Thank you all and GL, 73

Discovered a new COOL "feature" in this version.

Spotting 2 stations on the same frequency in the same timeslot.

I logged 130 "twofers" in October out of 60k spots. Mostly on 20 and 30 M, once on 10 M.

K4COD began seeing this when he upgraded to 1.6.1 as well. We had been running 1.6.0 previously.

I wonder how the decoder is able to work this magic. Very neat !

Thanks to all of you who make WSPR a reality.

anyone interested in using a cq100 ( 29.435 ) as a talk frequency for wspr?

Delighted with the new WSJT integrating WSPR with JT65 etc.

I usually run WSPR with a little Flex 1500 SDR but sometimes with an Apache 100D SDR - both at the 5 watt level. Antenna here is a low horizontal doublet about 20 long and about 5M height mainly for 80/40 NVIS. But with WSPR it seems to go OK on the higher HF bands.

QTH is RE78rs Martinborough (pop 1000) in the far SE corner of the North Island. Hoping to have a 12M vertical doublet up soon for better DX coverage.

Previous calls ZS6BCT, ZS1AMB, VK2BQM

I build ultimate3s beacon kit and it is been running few days on 10m band using my callsign OH1KK.

Yesterday I was really suprised when I saw spot:

2015-11-21 12:30 call OH1KK MHz 28.126094 SNR -24 Drift 0 Grid KP13un Pwr 0.1 Reporter SV9RMU RGrid KM25bl Distance 3123km azimuth 179

Boats have a problem getting HF through a forest of masts in a marina. Tui is currently in Hartlepool with the WSPR transmitting through the tuner and main mast back stay antenna used by the marine MF/HF radio. It has a clear view to the west, and a fairly clear view to the south but a forest of masts north and east.

This link should show where we are although the boats have changed since the photo was taken

Hi,

I had received 5 stations (!) en 136 Khz last 24h between november 14 and 15 :
UW8SM, M0DSZ, 2E0ILY, DC0DX, GW4NOS

Since septembre, I had received 11 stations en this band. I hope there is other !
I monitoring again ...

David, F4HBT

Its really encouraging to see the likes of Phil FR5DN on Reunion Island trying to give 2m WSPR a run along the path to South Africa (and Australia ;) ). I see we have ZS5LEE and ZS5HV monitoring at the far end. I cant wait to one day see some lines on the map!

Phil FR5DN has made this path to South African stations numerous times before on 144 MHz SSB, JT65 etc. Here is a link to Phil's website with some data about the Tropo paths from Reunion http://www.astrorun.com/~fr5dn/radio/tropo/tropo.html

This excellent web site is written and maintained by Bruce Walker, W1BW. We haven't heard from Bruce in quite some time; presumably he's very busy with work or other obligations.

I get frequent emails from people saying something like "I applied for a WSPRnet account and received a confirmation email telling me approval was pending. Then nothing... Can you help?"

I always tell people to contact W1BW. But I can guess what happens, because I can't raise Bruce by email, either.

Note: under development and very experimental.

Just by chance I was checking 10m around midnight and heard Dave, W1VR (EL98it) 5 times between 0552z and 0628z. First three decodes were strong at -6,-7, and -6. Finished with -24 and -24.

I was heard once at 0600z.

dxmaps.com was showing a sporadic E cloud in northern Georgia.

Other nearby stations WJ9H (EN53ga) and K9AN (EN50wc) had already been reporting W1VR for about an hour by the time I tuned in.

Sporadic E is an interesting propagation mode.
