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.

The RSP 2 has arrived and it's up and running. Some unsolicited advice for others... if you are looking for a "plug and play" device - any SDR, not just this one, you should rethink your decision. With infinite flexibility comes infinite complexity.

Never mind that I'm also wrapping my mind around magnetic loop antennas for the first time :-)

Still waiting on my WSPR Lite - apparently customs has devoured it :-(

My new QRPi Whispering Raspberry is now on the air on 20M from FM03xw putting out a whopping 10mw into an attic-mounted MFJ 1788 loop.

My setup is transmit only -- and the recommended Linux TX command has it transmitting MOST Of the time, unlike my Windows 10/transceiver setup where it listens more then it squawks. The start command I'm using is "wspr -r -o -s N4NVG FM03xw 10 20M"

Are there any other Whispering Raspberry users (or Linux people) who use/recommend a different command having the system remain silent for at least a minute or two between transmissions?

NEWS UPDATE – VY0ERC will again be active from Eureka, Ellesmere Island NA-008, Nunavut from January 22, 2017 until probably early April.

This is a location near the North Pole in Northern Canada. Info from here:

Here are the five (5) stations copied last night: WB5WPA, W3PM, K3RWR, DL1PT, G3KEV

For those of us in the Northern Hemisphere Summer is coming. Got a powerful PC on all day? Or an old XP machine wondering what you are going to do with it? May I suggest getting a RTL dongle (with TCXO) and setting up a 6 meter WSPR receiver. The dongle can be had for ~$25 and can run on that PC you have on already. Any antenna will work. Obviously a long yagi pointed to W6 would be ideal,but most anything will work when the band is open. Can be set up fairly easy just IM or email me if you need help setting it up. Northern EU and Asian stations Summer will be here before you know it.

Over the Christmas period I decided to dump Windows totally and go Linux.
Best thing I ever did really.

I now need to finalise my radio activities with getting WSPR running.

I can't make it work with WINE, so I wonder what others recommend for Linux ?

I'm running the latest LInux Mint 18.1 Cinnamon.

This is episode 5 in the Ultra Portable Digital Comms series and naturallu, it relates to WSPR. In this video we are setting up WSJT-X to run a bidirectional, man-portable WSPR beacon test kit. I've used WSJT-X, a Yaesu FT-817ND, and the ZLP MiniProSC, setting it all up on Ubuntu Linux.

the link

is my web site where my MEPT based on arduino and si5351 is detailed.

the .ino files for both FSKCW QRSS and WSPR can be found using the Github link at top right of web site.

I have yet to file the RF section of the MEPT but the block diagram of digital section is given.

I hope this proves to be of interest.



The v1.0 of WIZPit is now made open for sharing.

A link to its documentation is made available from:

Big congratulations to the stations involved with the trans-Pacific 6m Opening yesterday. Well done guys. This kind of opening is looked for by numerous operators every day so its good for some of the guys to finally get a great reward for their efforts.
As we are aware, WSPR was the only mode where paths were made, which goes to show the effectiveness of WSPR to identify these types of path openings, particularly on bands like 6m where openings can be very sporadic.

Running 1 watt from my Icom IC-7300 into a Full Wave Horizontal Loop at 30 feet.

Today had a first use of my WSPRlite transmitter using the antenna of PI9KLM on 40m and saw the first spots appear.
I am very happy to see it really works!

I noticed this on the Brendan Quest 2M Trans-Atlantic Attempt page on Facebook today. Maybe some others may like to try getting some signals in to VO1FN receive site.


I notice on the WSPR.ORG site there is quite a bit of activity on 2M....also the listening freq for WSPR is 144.489 which is the freq the VO1FN receiver is always on! Usually have the receiver set for 1500Hz audio offset. 144.489+1500=144.490500 --- I changed the mode today to WSPR-2 in WSJT-X and will leave it there for a while .

The antennas are pointing 60deg to Europe.

Haven't gotten out to Europe yet, but I have reached southern Brazil and West Australia.

Using this:

Ive joined WSPRnet to analyzer my new antennas. I have been licensed nearly 40 yrs. After 8 years away from the hobby I returned in 2013. Finally, 17 years after I poured the concrete for my big tower I purchased
