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.

I got my call G4BDQ in 1972 so I'm an 'old timer'. It's worse actually. I remember the crystal set I was given in about 1953. I spent ages fiddling with it trying to hear something but I was living right in the centre of Southend-on-Sea and I was about 4 so antennas were not possible. Oh well. I started building stuff rather later in the 1960s. I started with a DF33 one-valve receiver. Then transistors, OC71s, OC45 etc. came along but I didn't like them. Then I discovered JFETS. Oh yes, I liked them. Nice high-impedance things, just like valves. Fiddled around for ages.

I will launch my first WSPR balloon tommorow in Germany.
it is an modyfied Ultimate 3s Transmitter weight only 37g incl. solarcells and dipole antenna.
Here is the transmitting shedule:

tonight (26th of june) i will try my raspberry pi zero on 10m from my home qth.

Soon i will temporarely move over to Scotland and will try to set it up again for a few days.

I finally found time to connect my rig to WSPR. Not ideal as I am using a 3 el. directional antenna will use my Challenger DX sometimes in future for testing more.

Finally got the personal blog up and running @

I hope to make lots of informational videos over the coming months on WSPR, how to get started, and some common issues that I ran into getting up & running.

I've found WSPR to be a great alternative to use when I'm just so busy I don't have any desk time w/ the radio.

Want to thank all the operators out there who continue to make WSPR better everyday!


Set up my IC7300 today on WSPR with HRD.

Happy days. :)

Today, running a home made loop 1 meter across on 40 Meters. Tuned close and final tuning with ant. tuner.

Logged a station on 10Mhz WSPR this morning - Callsign P98WAR (N. Korea) from Antarctica !!! This must be a spoof surely!

It is necessary to install the icom usb drivers onto your PC. Go to Down near the bottom you will find for the IC-7300 the "USB Driver v1.20". Download and install this and then re-boot your PC. When this is done you can open Device manager and look for a Com Port called "Silicon Labs CP210x USB to UART bridge". Take note of the com port Number....This is the port that you will use for Rig control and PTT if desired.

Hello everyone.
Today I published a new Quick Start Guide for the WSPR Beacon app for Android, and the Yaesu Ft-817ND. It also includes information on setting up the Wolphilink interface. So many people have been having trouble with the WSPR Beacon app on Android so I thought it was time to publish a quick start guide.
