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.

WSPR and Win7 home edition 64 bits

hello everybody,
I was using WSPR under Win XP on my former laptop with great sucess. Since I changed my computer -now a desk computer under Win7 64 bits-, I cannot receive or decode any signal?
Has anyone got the same issues ? how to fix it ?
thanks for help

Astonishing conditions in 160m wspr last night

On one hand, some good dx report:

On the other hand, it is no longer possible to receive and decode George K9PAW usually very regular.
I'm looking at, there is not even the beginning of a trace on the waterfall????

See you all again,

My only dx that day at over 12000km.

Strange are the ways of 10m

Data analysis example talk on WSPRnet

Recently I gave a tech talk about analyzing WSPRnet data at a tech conference called Erlang Factory SF Bay Area 2013.
The slides is here: http://www.k2r.org/kenji/papers/file-archive/rikitake-efsf2013-radioandr...
and the talk abstract is here: http://www.erlang-factory.com/conference/SFBay2013/speakers/kenjirikitake
You can write about this at your blog.

Long path or short path (G<>VK2)?

Had a few spots from VK2DDI this morning on 30m.

To the best of my ability looking at computer models, the closest propagation
match would say that it was long path.

Anyone else agree/disagree ?

Either way, I'm just happy to have ben spotted with my 500mw and an indoor wire ;-)

Please help me to contact K7RSB

Hi,

Sorry if this is a little out of topic.
I have received orders from Bell Ross K7RSB on my online shop.
I need additional informations from him but it seems that he does not receive my e-mails.
Can someone inform him he can communicate with through this website, my blog or even checking the orders online on the shop web site... ?

Thanks for your help.

Raspberry Pi as WSPR transmitter up to 250Mhz

There is now a modified version of Dan's, WsprryPi that should be capable transmitting WSPR on HF and VHF bands, just with a LPF and antenna connected to GPIO4.

For experimentation, my code and binary can be found here: https://github.com/threeme3/WsprryPi

WSPR-X update

Today I have posted WSPR-X v0.8 r3058 at

http://physics.princeton.edu/pulsar/K1JT/WSPRX_08r3058.exe

Thanks to some excellent coding by Edson Pereira, PY2SDR, WSPR-X now compiles and runs properly on Linux as well as Windows. Some (mostly cosmetic) changes have been made to the GUI.

Important: reporting by WSPR-X to WSPRnet now includes information about stations being active on a band, and their Tx status, even when no spots have been uploaded.

A brief description of WSPR-X is now included on the WSJT Home Page. See
http://physics.princeton.edu/pulsar/K1JT/wspr.html .

-- 73, Joe, K1JT

PS: Sorry, but we don't (yet) have a click-to-install WSPR-X package for Linux. If you know someone who might be interested in creating .deb files for WSPR-X, please let me know.

WSPR-15 support

Sorry for the delay in getting to this, but I believe I have added the necessary site support for WSPR-15 spots. I no longer fix up spots with the timestamps on spots at :15 and :45 minutes past the hour. I have also restored the original times on all such spots over the few months. Please let me know if anything looks wrong!

Top Band Club

Per tutti gli appassionati di bande basse, è stato costituito il Top Band Club ( http://www.topbandclub.org ).

A presto, Federico

WSPR-15 enabled in Firmware 1.10 of the DDS WSPR beacon generator kit

Hi,

I have updated the source code for the WSPR agile beacon generator.
It has several improvements in the setting menu and now support WSPR-15 and an improved accuracy for WSPR-2.

The DDS beacon kit buyers can download it for free here and upgrade their micro-controller :

Neighbor's antenna, on the air

A ham neighbor of Erin's and mine passed away; I knew him slightly, having delivered some NTS traffic to him. His (former) house is currently being gutted by renovators, and his old 11-meter antenna ended up on the street for bulk trash pickup. Of course, I couldn't let an antenna go to the landfill without trying to save it first. The radiating element is a quarter-wave fiberglass whip sized for the center of the US CB band. It has three radials and came with about 25 feet of RG-8 cable. It also features the most severely weathered fiberglass I've ever seen; I've been handling it with leather gloves, a long sleeve shirt, a dust mask, and safety glasses.

I've put it up on a push-up pole so that its base is about 20 feet above ground. Using it to listen to the bands today, I heard a couple of west-coast 10M beacons, including K7FL. Now, I'm feeding it with 1 watt on 10 meters via a manual antenna tuner. We'll see how it works during daylight tomorrow!

WSPR with Magnetic Loop

Having always troubles with long wires, I decided to test a magnetic loop. Therefor I soldered a square 128cmx128cm, with 12mm copper pipes, organized a variable capacitor via ebay and but this construction on the kitchen table.
It is amazing - I got a spot from WB2EEE over a distance of > 6000 km, -28 dB, for my 10 watts, inside the building at the 1st floor.
Test showed me, that I can use it on 30m and 20m too. Let's see what will happen later this night on 40m. Tomorrow at daytime I will test on 30m and 20m with the antenna at the balcony.

50MHz WSPR

We're starting to see a few short Es openings here in Europe, so I'm proposing to start running WSPR on 50MHz in the next few days. Would be great to see plenty of people on 50Mhz WSPR too.

See you on 50.293?

VI100ACT

VI100ACT special stn CQ on 24.2225 in Olivia 8/125. Will be QRV till 1000 UTC today (6 MAR 2013)

VI100ACT

Unfortunately this callsign is unsuitable for WSPR, being mutilated when transmitting. I will therefore no longer use it in this mode. I will endeavour to come up in Olivia or ROS for weak signal QSOs. Will update the blog whenever I start.

Low RX nose / FT 857

Some info on the Rx audio output in combination with the Yaesu FT 857, I had to turn the RX complete open for RX nose +/- 0 db.
Yesterday I upgraded the WSPR software from 2.00 to 2.11 and got it fixed. The RX is now half open and the signal is 2/4 db, great!!

VI100ACT

This is a special callsign commemorating 100 years of Canberra/ I will be using this call until March 9 2013 on 12m digital modes, WSPR included. QSLs and SWL reports via the buro. A special QSL card is yet to be printed.

my last experience in wspr mode

Starting txing on 20 m

Got my USB SignaLink by post today and had it running in 30 minutes. (just two cables, and jumper settings). First to check the audio levels i used Digipan, then i went to WSPR.

My condition is 5 Watts on a indoor dipole. The Rig is a FT 897. After some 20 minutes i got a report from VU2LID..nice :-))

In the next days i will be testing on 20, 10, 6 and 2 m

Im always in for QSL, via bureau
