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.

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.

I’m trying to change my TRX (TS-680V to TS-870S) mostly for 160m band QRO.
Ref osc of TS-870S is normal type, so my WSPR reading frequency is not correct now.
But I’ll modify it to GPS lock within 2 or 3days. Please wait a little.



On 21-Aug-2015 Dave VE3KCL launched a balloon (in fact two hydrogen-filled foil "party" balloons tied together) carrying a 35g payload. The balloon is currently traveling North East a very nice speed! It is cruising at around 8,300m.

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.

I start WSPR beacon on 2200m today.
So far, myself is only station who get my signal.

I would improve location and ANT.
Pls try to get my signal.

Hi dear whisperer,
wspr has become my favourite digital mode. It`s absolutely fazinating. A few weeks ago I installed a Cushcraft R6000 to increase my wspr results. This antenna works very fine, it`s optimal for wspr. Nearly every day I`m heard or I hear stations from all continents. It`s a pitty that there are so much white spaces on the map but I`m sure that the number of whisperes will increase more and more ...

Hope to see you on my screen

Just started WSPRx by tiny transceiver: Softrock RXTX ensemble/Output 1w(max).
ANT : 40/30m - DP
20m - λ/4 GP

I made 160m LPF for my U3 and tested it with dummy load.
In JA, WSPR freq on 160 nor 80 are off limit.

Pls ignore my post on 160m

Toru / JG1eiQ

Tried 137kHz and blew up the TX
Back receiving on 160m with double bazooka -
Working out how to do TX with SDR-Duo...

Seems to work on RX


I have 2 FT857 at 10m online...
the first with a windom Antenna dd9lh/h 28.126050
the second with a Siro Gainmaster vertical dd9lh/v 28.1260150

whats better ;-)

I received good report from OC, EU and NA on 30m/40m.
Mani tnx.
I hope AS activity will be improved soon.

I'm trying to compare spots from 2 SDRs on same antenna using Windows 7 PC running WSJT-X. When I attempt to launch second instance, I get error "Another instance may be running, try to remove stale lock file?". Clicking YES or RETRY just repeats it, clicking NO gives an error "Multiple instances must have unique rig names". I tried changing the CAT rig selected to NONE and get same results.
Has anyone been able to run 2 instances of this application?

G7NSY will be transmitting only at 0.5W (-27dbm) on 20m via a Comet H422 Vertical V-Dipole mounted on a 20 feet mast in the next couple of weeks to see how well it performs. Transmission power is carefully calibrated at feed point of the antenna. Any questions/comments, please drop me a line. 73 de G7NSY Martin
