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.

For 24, 28, 50 MHz I have rear half of 10m 4 ele yagi (so just 2 elements) sitting flat on my garage roof. Boom is pointing south. There are various metallic items very close to yagi outside and inside of garage roof. Fed from Zachtek Desktop WSPR Tx (approx 200mW).

Good evening, I have just joined WSPRnet and found no map ? any ideas,

I've been running a couple of wspr beacons, Sota Beams wsprlite and wsprlite flexi, for several years and marvel at the places from which my signals have been reported. I would like to return the favour and become part of the reporting network, but I'm a complete newby as far as reception goes. Can anyone point me to a place where I can be instructed, in words of one syllable how to set up and run such a system, using a dedicated receiver if possible. I have a raspi 2c and several standard computers using windows 10, one of which dual boots with linux mint.

Based on the results shown By WSPR , have you ever used the numbers shown to calculate and improve a transmitting Antenna? Do you know of any examples as I am looking for anything to learn from - cheers

QTH temporarily changed to Amrum, JO44dq.

Problem with 4 digit locator solved. Everything works as designed. A look into the WSPR User Guide 2.0 did help :-)

Since a couple of days I'm located at the island of Amrum and am testing my little beacon. The power is 0.05W. At the moment I'm having problems with the GPS module connected to the beacon as it only transmits 4 digits of the locator - but I know, it's possible to transmit 6 digits. Today (06/07) I transmitted the wrong power and again only JO44 as locator - even though I updated the code of the beacon.

Will continue testing...

Just found a Ultimate2 QRSS kit from qrp-labs in my drawer, power it up and it works!

Modified the Raspberry Case to allow plugging the module with extenders off the Pi.

Antenna is my gutter and downspouts on my house facing east.

Hello everyone,
recently due to lockdown restrictions I started building stuff form ham shack.
Loving WSPR I decided to build a transmitter using a simple Raspberry Pi, just using
the maximum power of 10mW. And here.... are my results....

Glad I found my way to this website. Now I can assess my antenna and it’s performance. Also I can use this to adjust the direction of its broad side signals to suit me needs!!

To have an idea about the 160m propagation, I tested during one night this feature. Using an FT450 with 5 Watts into a vertical antenna 10m high with a loading coil at the base.
