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 have had my 80M WSPR station running since yesterday on 80M to get some baseline data, as well as data during the eclipse here in the path of totality.
I was a little worried last night when the FT8 crowd busted in on 3.572.6. Their big signals really were overlapping the WSPR bandwidth. Fortunately, today didn't see much FT8.
I was outdoors observing the eclipse, but had set the station to TX 50% of the time. Hopefully others along the eclipse path noted my signal improving around 17:15-17:25 UTC.

Lots of activity today for the eclipse. Fascinating to watch

Upgraded Mag loop with large split stator capacitor. Still using two, joined 1.5m RG213 lengths for loop with RG-174 loop feed.

Well, my rig interface just went out, so I won't be able to transmit during the eclipse.

I will have my "gorgon stare" 160-10 meters CW, WSPR, and JT65/JT9 receive array online and reporting to pskreporter (cw & JT) and (WSPR).

its a pain in the ass to setup

#Back2School time , after some temporary operations the my WSPR beacon will now full time operational on 20M band.*
With an WSPRLite (from SotaBeam) Autobeacon with 200mW & G5RV (Full size 32m / 102 feets) feed center 36 feet high).
Powered from network grid to USB Voltage (re-start and time reset could happen time by time).
Will be glad to receive some reports if you can heard it.
Hope to read you soon.

I've been struggling a bit to get three stations on the air for the eclipse. I think I finally have it - I don't think I was driving the audio sufficiently. I've now got reports on 20m, but waiting for 80m (currently 1300 EDT/1700Z) and 6m (waiting for the magic). I see a local guy (K1EHZ) on 80m, so he should be able to spot me if I am really transmitting.

Using WSJT-X - I couldn't get WSPR to control my rigs as easily, and WSJT-X was kind of plug-and-play

In time for the eclipse, we have just released a free Android app for WSPRlite. WSPRlite-to-go allows you to program and use a WSPRlite in the field. It uses timing and location data from your Android device too.

WSPRlite-to-go is a free download at

I'm trying to set up an unattended monitor but can't keep the WSPR software running for any extended period. I turn things on and walk away with everything FB. Within a day it drops out and I get the following:

"Microsoft Visual C++ Runtime Library
"Runtime Error: Program: C:\WSPR\wspr.exe
"This application has requested the Runtime to terminate it in an unusual way.
"Please contact the application's support team for more information."

I was able to catch a good buy on this 918ssb mchf pre build. I have Parkinson's and can not build one. Soooo I bought one at a fair price. It is a great little radio so far and starting today I intend to put it through its paces. I have spent two whole days getting the entire station ready for portable ops. I intend to run a bit at .5 w and see how the unit as a whole stands up. So fa,r CAT control has been a real blessing. I intend to use this entire setup for SOTA / Emergency work. I may or may not keep this blog posted.....

just up late h I h I

They have my membership date wrong on this site. It has been at least 4 years. OH well, It's not important. I'm building one of the QRP-LABS 200 milliwatt WSPR beacon. I already built the QLG-1 satellite synchronized clock receiver; which works fine. I think it is a well thought out design and circuit board layout. It has nice big solder pads to get the 1 pulse per second timed pulse and data output to connect to. This device synchronizes the WSPR transmitter to send the signals at the proper time.

Hi Just trying the software...

Low Flux.
Everyone on vacation.
Yech on HF.

I'm totally amazed at what 1W can accomplish. I've seen my call sign spotted in Australia, Brazil, parts of South America.... All over the place. Just 1W. I am really enjoying WSPR.
