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.

Hi, W7FJ put up a video of my VCXO-AXE using a GymBoss as a timer:

I also want to point out that there is an accessory timing board that I developed
which I have used for over two months continuous without synchronization loss.

Anyway thanks to a user for the youtube video; thought others might be interested.

Hi all, just to let you know, a while back I created a Facebook group for 160m WSPR enthusiasts. There is a few people who have joined the group from different countries, its quite good and easy to advise of your activity and meet up with friends with similar interests.

As a bit of an experimental thing, I thought I would make some group pages for those interested in 10m WSPR and 6m WSPR, just to see how it would go and give those on Facebook an interest group that caters for them too.

I finished the receive portion about a week ago but for the life of me could not seem to pick up any signals. Had what seemed to be signals on scope / waterfall but nothing decoding in any software.

Last night I went out and got a set of speakers so I could hear as well as see what was going on. Tried using a headset before but can't really walk around the house with them:)
This way I could just let everything run and come to the radio if I heard something.

I built a Softrock RXTX Ensemble transceiver for 40m/30m/20m. Running it with WSPR 2.11 r226, I made my first contacts with the transceiver today, running it with a pack of rechargeable cells, wired to a Creative EMU-0204, with no PowerSDR or VAC. I will be describing my setup in a separate entry soon.

Dear, it's a 3rd day in a row I am able to hear as well as am being heard by VK0TH Travis at Macquarie island on 30m/WSPR around 21-22z. Wish we could try JT65-HF one of these days while conds last yet...

Been tinkering with Ham radio for over 30 years, got licensed in 1982. Since those days that have gone by I have tinkered with SSB,PSK31,JT65HF,HELL Modes,and recently found an interests in RTTY.

I live in the Philippines at the moment with my wife and son, and I usually spend alot of my free time operating on the bands. Last few years its been 6m as well as the others. I find the hobby to be very rewarding and more enjoyable than anything else.

Here I am...first time logging on the wsprnet! Glad to be here. I will be on the learning curve for a while but hope to get talking to some of you folks out there. I am only on 30m with a small j-pole antenna, so I don't know how many folks I'll be able to talk to. Best wishes to anyone reading this!


Last night I compiled, and wrote a quick how to compile WSPR 3.00 under Debian testing (wheezy) amd64 and the problems I encountered in the process.

I was surprised to see MY OWN call sign and decode appear in the decode window, history window, as well as corresponding signal trace on the spectrograph!

Not considering unlikely things such as reception of my own LDE (Long Delay Echo) or some other amazing effect... or someone using MY call sign, XMIT frequency and power settings, or recording my beacon and retransmitting it, what could account for this strange event? It has happened on three different occasions.


Thank you all for the support you've given me regarding the WSPR animated GIF generator program! I've tweaked it, added a few features, fixed a glaring bug, and have released version 1.0 at this URL. Please continue to send me feedback, bugs reports, and ideas for additional features!

PS - For those of you that used it and got the dreaded 'No Spots Found' message, please try again.

From time to time WSPR's reports a decode that is just "Too good to be true".
To a newcomer they are something to get excited about. Is this WSPR mode really that amazing.
Sometimes they just "don't look or feel right" to an experienced WSPR's eye.
Sometimes they are just plain "WRONG"

If it fails the Database filters, IT thinks it is Suspect and is simply not entered in the DB.
If it passes the Database filters and is entered it may still be suspect.
Filters are not intuitive, they don't ask all the right questions and think about the Answers.

There are a few simple checks you can do, that should confirm if a Decoded Spot is Suspect.

Date and Time are rarely suspect, unless you know you were not on air at that time.

Look at the Callsign, Is it a Normal Format (prefix, number, suffix), recognise the prefix?
No, a quick check with or a similar DX Call book Listing.
"The search for 6p7frs produced no results!, MMM, 6p7frs looks like a callsign from Pakistan".
Not a good result, Suspect ?

Look at the Band/Distance, 50MHz, 5123kM, a Long way to go on a quite band, 1600kM is my best DX today. Not a good result Suspect?

Look at the S/N ratio -29dB, thats right at the decoders limits. We know WSPR was working very hard trying to decode something, ALL_WSPR.txt confirms the 6p7frs data looped through the error correction system 16,018 times to produce this Decode. Not a real good sign!

Look at the Grid Square BG24 the WSPR Map tells me in the middle of Antartica, Only 4 digits, A Pakistani in Antartica far from all known bases. Not an expected result Suspect?

Look at the Power, 501 Watts, Odd figures, Wattmeter that accurate?, Not really QRP,
(10 Watts or Less). Again Not a good looking result Suspect?

So our Suspect Spot Below Failed on most of the Simple Tests and I Believe it should be consigned to the Bit Bucket where it obviously belongs.

Well, I joined WSPRnet and made an account some time ago but just finally started actually using WSPR now that I have decent HF radio.
I now have a Yaesu FT-450 and am amazed at how far a low watt signal will travel in wspr.
I am really enjoying this mode and seeing so many stations active around the world.



After getting very positive feedback from many of you regarding the WSPR map generator I wrote, I decided to go ahead and make it available to all Amateurs. You can find it here.

Remember, it's a beta, and for now there's only data for December 1, 2011 thru 23:58 on the previous UTC day (assuming my auto upload scripts work!). Please enjoy!

Some of the features:

Since I started WSPRing 3 years 38 weeks ago on 30M, I have heard data signals above the Wspr slot. Of course you actually listen to the audio when starting Wspr.

Just this morning I heard a JT65 signal inside the Wspr passband, starting up WSJT I monitored the JT65.

It was a C91 station sending a CQ, also on the WSJT waterfall was my old data signals.
Looking at the screen capture it looks like a narrow FSK signal from one station to another, one strong (S9) and the other weaker signal in return, then stops.


If any 160m WSPR enthusiasts are interested, I've recently opened a "160m WSPR" Facebook page.

Just myself and Derek VK6DZ on there at present, but others from around the world most welcome and let us know what your up to in the world of 160m WSPR.!/groups/149900118453784/

I had the need to download a number of WSPR CSV files so I threw together a PowerShell script. If anyone has the same need here is the PowerShell code to use as is at your own risk. It goes out to the WSPR web site and downloads the month you specify unzips the file and then creates a CSV file with only spots containing the call specified, then it deletes the downloaded ZIP and associated CSV files leaving only a file by the name of the call specified .csv. This was coded for a quick project and DOES NOT have any type of error checking and it assumes you know what input parameters are needed. I named the script download.ps1 and it needs three parameters: the year, month and call. If you run the script multiple times using the same call the results will be concatenated into the one call file.

# Script to download WSPR spot file, unzip file and create a specified call file.
# By N9RO January 01, 2012
# To run program CD to the script's directory and type ./download.ps1 year month call in the
# PowerShell window. New call file will appear the the script's directory.
$source = "$year-$"
echo "***** Downloading file: $source *****"
Get-Date -DisplayHint time
$destination = "c:\projects\wspr-adif\wsprspots-$year-$"
$wc = New-Object System.Net.WebClient
$wc.DownloadFile($source, $destination)
echo "***** File Download Complete *****"
# Now unzip File
echo "***** Unzipping WSPR File *****"
Get-Date -DisplayHint time
$shell_app=new-object -com shell.application
$filename = "wsprspots-$year-$"
$zip_file = $shell_app.namespace((Get-Location).Path + "\$filename")
$destination = $shell_app.namespace((Get-Location).Path)
echo "***** Unzip complete *****"
# Create Call file

You all have the best New year ever... May good things come your way this year 2012...
