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.

OK, it's a click-bait title, I confess :-),
It is about using Lasers to transmit WSPR.
Pretty cool regardless, more info on my blog


New to wspr, i m happy to try it and see that 5w of power can be heard so far away !
see you on the waterfall

From 2019-07-25 until 2019-08-10 I'll be operating from the Baltic Sea coast (JO45rd). Rig will be FT-857 (up to 40 dBm) into a matched 6.3 m vertical.

Just curious what kind of antenna you are using on 160 meter WSPR band.

I’m new to digital modes even though I’ve been a ham for many years. Thanks to those who contribute.

This still works if you are not inclined to fool around with google, and if you use an ad blocker of some sort --->

On my systems, I got rid of that annoying "Development Purposes Only" message on the Maps produced on this website.

I was poking around in "Blockable Items" as I often do to speed up page loading or to get rid of the pop-up crap and script snoops, and found that blocking this item ---->

just looking for activity on 6 meters

I decoding to 6 channels of WSPR simultaneously on the KiwiSDR.
Decoding and spotting can be done without a PC.

Here's my favourite WSPR spot of late:

2019-07-04 20:10 MM3OQR 28.126041 -12 -3 IO87we 0.5 FY5KE GJ35 7244 238

I think 7,244km is probably my distance record for 10m. :-)

KP4MD/P is active on WSPR until July 14, 2019 from (FK68xk) Carolina, Puerto Rico, on the north shore of the island.
Radio: Elecraft KX3, 5 watts on 20, 30, 40 and maybe 80m.
Antenna: Buddistick monopole at 40m elevation over the Atlantic Ocean.

Hi all.
If you want a 10 minute of technical read and pictures you might want to check out my latest blog entry here :
It details how the Polar Research vessel Oden now runs a WSPR transmitter on board while on summer expeditions.
It usually travels to the South or North pole every summer.
Right now it can be followed on WSPR as it is heading for Greenland.

Another interesting 10m spot. I spotted G8CQX-IO81xu (20W) on 10m at an unusual time (local time 3:08 a.m.) This was more than 2 hours before sunrise. About 1.5 hours before dawn, and 50 minutes before nautical twilight. It was, however, about 5 minutes after the start of astronomical twilight (time when full darkness ends).

Wales, Wisconsin
Astromomical twilight begins (full darkness ends) 03:04 a.m.
Nautical twilight begins (First light) 03:59 a.m.
Civil twilight begins (Dawn) 04:44 a.m.
Sunrise 05:19 a.m.

Heard IW4EGP using 5 Watts on 10m during a sporadic E opening at a distance of 7562km. Here are the spots of all the stations hearing IW4EGP JN64gb at 1452Z on 2019-06-21.

I haven't posted here in a while!

To help encourage more WSPR activity on 28 MHz, I will be on receive only from time to time during the Summer of 2019.

I usually monitor the FT8 frequency most of the day and feed the spots up to the PSK Reporter website. I have my radio set up now so that it's easy to switch to the WSPR frequency and feed those spots to the WSPRnet website.

I'll probably do this by listening for WSPR signals for 10-30 minutes at a time when the band seems open before going back to FT8.

Hellow fellows 73 to all i will make portable operante vertical 20m test nem antena 10m wire and 16 radiais 1/4wave lets see um 1h tks hope all good 73/dx PY1AX tony
