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.

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.

Currently running on 150mW with a raspberry and only one wire as an antenna...

I normally calibrate the receive frequency of my RTL-SDR receiver against the local VK5VF (GPS locked) beacons but these appear to be offline at the moment. I'm unlikely to be receiving on the correct frequency for the time being :(

Nice event this night(July07): running 10w and then 5w, the S79V dxped has been heard in Europe between 22:16 and 23:10 by 11 stations on 160m wspr:

Thanks to team member Martin (A65DC) who planned this opportunity.

Hi all

After 20 days flight, Dave VE3KCL's QRP Labs Balloon S11 has completed a circumnavigation. See tracking at

Noise floor on 40m was s9 +10. No spots. Decent activity on 20m.

Currently on 40m Grid DO33MT

See the "General" forum page or this Pointer for a summary and sample waterfall/wav file of the June/July 2m WSPR activity across the Pacific. Work is progressing on a 70cm WSPR/JT9/JT65 addition to the existing KH6HME beacon on the Big Island as well.

No waiting, no resting times on 160m during summer. Each night gives opportunities to heard NA stations.
This night (july04) five NA stations have been heard in Europe: K9PAW, K9YWO, W8AC, AA3GZ, N9LYE.
My RX Challenge score is now up to 6 for a new season:
A friendly greeting to David EA1FAQ as new "big 160 ears" in Europe.

Good luck all, 73, Patrick

Transmission yesterday and today have been on offset dipole up 30 feet. Switched to 3 foot long ferrite loopstick antenna at 18:20Z on Sunday, July 3rd.

I just run an experimental setup for next 4hours from now. (until 20:00 UTC)

Conditions here:
- cloudy sky,
- Cha-F in 5m hight on an 3/4 covered balcony (only open in sw direction) and
- running 10W.

Today July 2 2016, PI4KGL is QRV with WSPR TX/RX during our PA6CASTLE event from Teylingen Castle in JO22GF
