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.

As of April 15, 2013 any propagation data generated by my station reflect the results of my antenna experiments involving elevated counterpoises.

If anyone can give me step by step instructions on setting up two instances of WSPR under Linux
I'd greatly appreciate it I have both Signalink USB sound devices and CAT control working for both rigs.

Now I need to set it up so I have two /.wspr directories in my /home directory somehow and how to start each instance. I think.
Both .wspr directories can't have the same name I am sure.
I need Help.

edit I got help

I set up a second user named wsprtest
From a console

An open question for the WSPR community:

If you had a dedicated WSPR beacon transmitter, how many bands should it be able to cover automatically? If more than one, should separate antenna connections be provided for each band, or should all bands be available at a single RF output?

Thanks and 73,

6m WSPR JA-VK was successful.
Now I'm preparing to work on 2m WSPR.
Is it possible to decode signal from DX stations?
I'm worried about heavy spectrum spreading during the propagation.

Thanks Guido PE1NNZ and Dan's,
for nice project WsprryPi

24 hours ago on 40m with GP and 10mW from Bare Raspberry PI/GPIO4 + BPF
My WSPR2 signal received in 1 minute :
2013-04-08 22:08 LA9JO JP99gb 1650km SNR -23
Now tried on 20 m and got reports from Norway, Germany, England, France ....
2E0BMG JO01lv 2397km
F4EFL JN16qh 2593km

Due to several requests I've added a linux frequency hopping HowTo my previous blog, scroll down to the bottom to the page

1/2 watt to my new 17 meter dipole today being heard in both the US and Eu. Still amazed at what very low power can do. Maybe milliwatts should be my next step. Time for an attenuator.

I recently declared WSPR-X V0.8 r3058 a Dead Duck when Bob W9RAN and I both Failed to make it run on our XP Pro SP3 systems despite numerous fresh downloads and installs.

Thanks to Alan G4ZFQ, Justin VK7TW and Paul PA0OCD I now know that it Not a Good Idea to Install the program anywhere other than in C:\wsprx or D:\wsprx

A fresh download and install to C:\wsprx followed by a exit and restart after entering the station parameters and setup data resulted in the Dead Duck coming to life at last, receiving, decoding and updating perfectly.

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.
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.

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.

Dear all,

After a large amount of head scratching and research I finally managed to get 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.

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.

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

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.
