I notice an unpleasant increase in the number of stations using QRO in WSPR mode.
Could any operator running such powers please let me know the reason of this nonsense?
5W is A HUGE LOT of power on WSPR. Sort of running SSB at 1 kW.
10W is MEGAPOWER.
20W is OVERKILL.
50W is MADNESS.
Why such an useless waste of energy? All those watts will not get you any further nor any better or sooner than 1W - it's WSPR honey, no pileups to crash for showing how macho you are, get used to it.
I understand that many operators set their machines at minimum power, which usually is 5W. Which still is a lot of power. Well, build a simple attenuator and join the fun - satisfaction guaranteed.
The fun on WSPR begins at 0.5W, set your database on "miles per watt" and discover "who is who" in WSPR.
After all, those first two letters on WSPR mean WEAK SIGNALS.
Please stop polluting our frequencies with those unpleasant strong signals. Thanks.
It seems that something in my neighbourhood has parked itself on the 30m WSPRnet frequency. Can't hear a thing!
Trying out 20m instead!
I've got the information that JA-VK path on 6m will open about 2 to 3hour everyday at around 10:00GMT.
So I intend to work on 6m WSPR tomorrow night. Please beam to JA and watch my signal.
After a large amount of head scratching and research I finally managed to get wspr_nogui.py to run stable on a headless Raspberry Pi, the main issue was mostly due to the well known Raspberry USB sync issue, it was finally resolved with a work around (force USB port to 12 Mbits/s USB 1.1). I've put together a simple howto to help others with enough time on their hands to try this.

I have recently been working on a Genesis G59 HF + 6m SDR kit which I purchased as "built but not working".
There have been a number of issues, both from the build process and faulty components, but it's not a massively complex radio, and 99% of the components are standard through hole mounting rather than SMD.
It is now fully operational on receive, and will hopefully be transmitting a whopping +10dbm within the next week.
As the only HF aerial here is a 1/4wl vertical for 40m, that'll be the band I concentrate on first.
There are still a few calibration issues to resolve - mainly the frequency calibration of the si 570 - uCP interface which is currently a few khz off frequency and led to me spending a whole night of listening to nothing before realising , but it is now up and running.
There is a blog of progress if anyone is interested at

Hello all, thanks to Guido PE1NNZ and others who made WSPR beacon SW for Raspberry PI. I'm working no on the Raspberry PI WSPR shield with PA and filters. There will be 4 filters and 4 antenna outputs (SMA connectors will be used). The filter are switched by GPIO ports from Raspberry. There will be some mods of SW needed. The filters are plugin modules. Two options of filters are available. Bandpass filter or low pass filter. The are filters are made from standard SMD 0805 capacitors and coils. The PCB for base board and filters is now in the factory and comming i hope in 3 weeks. There is also space for PA module. I'm working on PA with power around +20dBm with MMIC. When you can't use PA you can simply connect output from Raspberry to filtes by jumper. I hope that this board will be simple platform for making WSPR beacons...

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
On one hand, some good dx report:

including a new US station in my listing: AD5UQ
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
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.

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 ;-)

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.

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
Today I have posted WSPR-X v0.8 r3058 at
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
-- 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.
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!
Per tutti gli appassionati di bande basse, è stato costituito il Top Band Club ( http://www.topbandclub.org ).
A presto, Federico
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 :

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!
