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.

Greetings fellow WSPR enthusiasts ....

I have been experimenting with ultra low power transmissions on 80M.
In particular, between my QTH (Saratoga CA, near San Jose) and a former marine radio station KPH.
KPH is located 123 km from here, heading 320 degrees, on the CA coast. (http://www.radiomarine.org/)

For unknown reasons the propagation between KPH and this QTH can be exceptionally good
and quite repeatable. A Virtual Waveguide might be a good description.

Just got my WSPR on the air. Xiegu X5105 on an vertical Moonraker GPA-80F 10m AGL.

HF is (slowly) coming back !!

Hi, I am qrv on WSPR not on a regular base but rather occasionaly. Yesterday when I worked on various HF bands, I found that radio propagation on the higher HF bands (21MHz and up) was excellent. So I decided to put WSPR back on the air once I finished qso-ing on 10m. I found that 21 MHz produced a few spots, where as 24,8 and 28 none. I may have to check the accuracy of my dial setting (calibration) on my Electaft K2 for the higher HF bands. 18MHz and 14MHz work fine! Have fun on WSPR everybody!! DL2GAN (using +33dBm, 2W on a 7m (21ft) vertical).

Statistical analysis of WSPR reports over a two month period indicate that the actual relative gain patterns between antennas 1 and 2 correspond to the modelled gain patterns. The antenna model and simulation results were obtained using the Altair Feko antenna modelling software. Included in the model is the wooden tower and attached structure. The attached structure is a 10-12 foot wooden shed that houses the remote antenna tuner. The wooden tower has minimal effect on various antenna gain patterns, but it does have a notable effect on the each antenna's resonance. Resonance is lowered.

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 ---->
