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.

What a better start with every nights dx spots across the pond !

My 160m season list of NA stations heard is well under way:
KJ4YBS(5w), K9AN(2w), K9PAW(1w), K9YWO(1w), KD6RF(5w), W3PM(1w), VA3MW(5w), N3CO(5w), W4DEX(5w), K4LY(2w), N2NOM(5w), KU4XR(5w), N8OQ(5w).

May be it's a right time to have a look also to 630m...

Thanks to all and GL, 73, Patrick

Oct 5th, 2015, 3..4:00 UTC:
many contacts on 630m over atlantic ocean.
Thanks so much to VE1HF, VE1VDM, W1TAG/1, WA3TTS/2, WE2XGR, WG2XJM, WG2XKA for spotting us.
I am using an inv-W antenna, which looks like an inverted Double-V. The balun is near the ground, then two vertical elements go into the trees (height 35m).
Then it goes down again to 3m. Total length of the antenna is 280m.
My neighbor (DH5RAE) uses a full size horizontal dipole in about 40m height, total length also 280m.
The wires are tuned to resonance with a RigExpert analyzer.

this new version comes with the newest WSPR decoder by K9AN for K1JT's Weak Signal Propagation Reporter (WSPR) mode.
This decoder has the new -d option which makes a deeper search and gives more spots.
This option is activated in wsprlinux by default.

other news:

* extended timer: up to 5 timers to select band(s), separated for RX and TX and also TX interval.
* a couple of bug fixes
* optimized caching of data to reduce network load of's data and's pictures.

I've been listening to WSPR signals for several years mainly with a Yaesu TF-450D on various bands but only occasional ran the TX part of the program, however, over the last few weeks, I have up-dated the software on my Office PC and installed PowerSDR and WSRP 2 and fitted my Flex 1500 with a MFJ-971 Tuner and connected it to a 40/80 Trap dipole at about 5 meters high. This now allows me the chance to run WSRP most of the day and night and despite the simple Antenna I am surprised how well the system is working.


On 24-Sep-2015 Dave VE3KCL launched a balloon from near Toronto (in fact two hydrogen-filled foil "party" balloons tied together) carrying a 35g payload. The balloon is currently travelling East, about to leave the US East coast. It is cruising at around 8,000m.

The electronics payload Dave built has a GPS, battery, solar panels, QRP Labs Si5351A Synthesiser module, and Arduino Nano (for low weight) that runs the QRP Labs Ultimate3S QRSS/WSPR transmitter firmware, but a slightly modified version.

My "shack" computer is just your average set up: Windows 7 O.S. Dual Core 2.0 GHZ machine. Operates most all WSJT software without a problem. The rig I use the most for WSPR is a Flex 1500, which does a great job for me. Recently I started using WSJT-X v1.6.1 (r5823) for WSPR and JT-9,all went well until I asked the WSJT-X to band-hop with the Flex.

About this time I come back online on 160M WSPR. I run a remote base NE of Toronto (VE3 land) and my 160M antenna is a 1/4 vertical (mostly) with elevated radials. I say mostly as the vertical part is over some very very tall trees. It then curves around like a trombone for the last 40 ft or so.

I'm running 5 watts and will try to be online unless I am playing in some other mode (like 160M JT65). Last night I was able to do a 2 way with VK2KRR during my sunrise. Yes, greyline does seem to work, doesn't it.

My WSPR-2 decoded the signals from WH2XND (in Arizona U.S.A. ) on Sep 13 2015.
The WSPRNet calculates the distance is 9,254km far from there.
My RX system is a 23m high mono-pole and direct-conversion RX at remote site. I`m
listnning to almost whole houres via VHF link.

Title doesn't sound spectaculair. However the antenna in use is a magnetic loop standing on the floor inside my garage. The transmitter does what it does en sends it's signal every 22 minutes. If you look for a received report by me you'll not find it. I'm sorry for being anti social. Working on a receiver solution without the use of a computer.

This transmitter works independent from my base station and mains. It is powered by solar energy. Thanks for reports everyone!

I am using a four-square receive array. This was at my sunrise, but I was listening perpendicular to the most likely path. We did have geo storm, so I am thinking this was a skewed path that the signal followed. Anyone else observing interesting prop on 40 or 80 in the last 24 hours?

Now were finally settled in our new home following a move of QTH, I've started retesting and experimenting with both small active loops, and Crossed Field Loops. Most of the experimental aerials are between 0.5 and 1.0 meters in diameter. So testing on 160 meters is interesting.

Alan M6NNB wrote very nice software for Hermes lite

Now I can decode WSPR on the same time on 2-3 bands!
and TX ing with 100 mW on my Hermes-Lite
Some my result in screenshot - in 1 TX 20m 100mW

At present am doing some part time experiments with various antenna's.
20-10m Cobweb of dipoles @ 13m.
40/30m corner fed delta loop @ 10m
80m inv Vee Dipole @ 15m.
No 160 at present but later in year will be a 22m vertical.

My friend kindly winded a coil for 600m.
It is working fine with dummy load.

I would get license for 600m in Y2016.

Using a Flex 1500, PowerSDR and a 10m ProWhip multi-band GP vertical.
My antenna is situated approx 6m asl and around 50-55m from the sea itself.

Currently utilising WSPR-X and am very keen to learn about and use WSPR-15 a bit more so watch this space!

Set up my KX3 using Signalink interface to PC running W7.
Band conditions are really poor on 20 Meters buy I am getting reports in CONUS.
This is very interesting and i am sure to enjoy it more as time goes on.

I am able to control transmission but I can not change frequencies from the software.


Im an looking for a Station to test with me the 6 meter Band.
My Antenna is a two Element Yagi on 15 meter hight.
I am a farmer in Namibia 180 km South East of Windhoek.
Look for QRZ Com to find me.

Hi Mark, copied you on 4m early this morning.

Unfortunately, I did not decode your callsign sequence, so did it not appear on WSPRnet.
One of the disadvantages of the force locator grid mode.
I usually see your Tx all the time, but no decodes due to aircraft reflections etc.


Let's try here, forum has not worked.
