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.

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.

Now WSPR-X v0.9 r3621 is working on my RaspberryPi 2 model B.

This weekend, I am testing out an end fed 1/2 dipole for portable operation on 20 meters. Nothing fancy. Matching network is a 8:1 impendanc transformation with a resonant tank curcuit. At the time of this posting, I have the antenna strung across the radio room on the second floor on the house. I think it a good worse case test scenario. Running 1W from a Yaesu 857D.

Now have an Ultimate 3S and RD15HVF1 up and running 80 thru to 6m.
Is it me or is 12m the definition of an RF black hole.....one spot in 2 weeks.

I'm sitting on 160 metres, trying WSPR 15 - but there seems to be no central logging system. If anyone is hearign me, please could they let me know?

And I will post anything I hear here.

Dear OM's,

I've just finished my 50W PA, so hopefully my signal will increase for ca. 12dB. So maybe it's enaugh for my first CW QSO's...

If you can read my whisper signal with a fair SNR please contact me by mail DL6II (at) darc (dot) de for a sked.

I got several questions concerning a curtain rail
acting as 'multiband' WSPR antenna.

Some people at my radioclub didn't believe me and
demanded a picture.

As promised, here is a picture of the WSPRing contraption.

See attachment.

After wspr with a raspberry pi I ordered a qrp-labs 3s version for wspr. Lets see how that works.

I've been decoding VK2KRR on 432 MHz today... 1018km @ 40dBm.

Fantastic!

It never ceases to amaze me when I play with Qrp and antennas. A few years back, I happened across wiring from a well replacement, heavy three strand copper coated with some waxy stuff. My first though - a 160M loop !. I had never been on 160M. So, I spent a few days, unwound the three strands, and started out through my back yard, hanging the wire off trees. Back at the beginning, a piece of Plexiglas for support in a 35 ft tower, to twin lead, down to a 4:1 balun, and into the shack.

What a better start with every nights dx spots across the pond !
oct1=16, oct2=27, oct3=112, oct4=51, oct5=109

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 wsprnet.org's data and qrz.com'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.

Hi

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.
