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.

Am trying this for the first time this week, and seeing some great stations, I am now pushing just 10 watts. I tried it at 20 but decided to drop it even more. I mentioned this program to myolder brother who is also licensed and will see if he gets involved soon. So far my screen see's this and I hope it will tell me more on those heard and seen.

Today I tried logging in to my WSPR account from the VE7UBC clubstation, where I am visiting old friends. Password refused !! Retried several times. Then the login prototcol freezes my account and I am locked out.

I was able to recover OK, by using the forgotten-password protocol. But only after waiting a few hours.

Someone had switched the keyboard to Canadian-French. My password has high-security non-alphameric symbols that don't map to the usual keytops in the Can-FR map.

I am using this antenna from 60mt to 20mt bands

Currently I am running WSPR on a Raspberry Pi 1B and using the Tucson Amateur Packet Radio 20M WSPR Board. Output from the Board goes to an attenuator to reduce the output to approx. 50 milli watts.
The antenna it is connected to is a Small Dipole via a MFJ-971 QRP tuner. So far only been spotted by local station within 180 miles. The Setup at this stage is in a small cardboard box, and

DF1VB from Dortmund/Germany has been coming through to VK3 with exceptional consistency over the past days. This station is ideal for propagation studies, especially on 30m. Band opening and max/min propagation times can clearly be derived from the reception data.
The attached image shows how DF1VB's signal still persists when all other stations have disappeared.

I've just been reading the latest IARU R1 Newsletter.

It is available here -

Downloads it and it says that (about 80% through the document) that there is a recommendation
to "remove all dedicated WSPR spot frequencies and footnotes from the VHF managers handbook".

Have these guys at the IARU got a serious mental problem ?

Today ZL1RS picked up my signal, this is the farthest a WSPR signal on mine has reached thus far.

Previous equipment was a HackRF into a MFJ tuner, and a simple homemade filter, mostly on 10 meters, and the greatest distance then was to Brazil or Italy.

The equipment today is a Raspberry Pi running WsprryPi into a QRP Labs 30 meter filter, into an MFJ tuner.

Some field day activity now in KP41DB with FT-817 (1 Watts) and quit an old portable whip: MFJ-1621.
Trying this time just 30 meters band.

Just looking through my log for 40M and surprised to see F6BAZ long path -20dB with 0.2W. Quite a good result.

What a surprise in this beginning of May! 160m dx season is still open. Each night provides some few NA dx spots; this night (09May) KD6RF, K9PAW, W9MDO, W8AC were heard in Europe between 02:20z and 04:20z.
Usually we see a quick decline at the end of april of the daily spot count (below 2000). To compare to 08 May figure: 5853 spots.
That is a unique situation in last five 160m seasons. So let us take advantage of this extended time!!

Currently TX on 28mhz with either 5w or 500mw into a vertical antenna beautiful sunny day 75 deg F

I started at 20m with 5 watts. 5 watts is very much for WSPR. I now use 0.1 watts and with excellent results.

Hmmm, I'm seeing multiple decodes from SM0EPX/RX2.
Not just from me, but everyone else too.
Typically reporting everyone 3 times for the same transmission.

que diferencia hay entre JT65 Y WSPR,
me pueden explicar que característica tiene
desde varios años hago JT65, este programa se pueden hacer más DX ?

desde ya gracias

Working with a rigid dipole at 6 meters, and 20 watts.

For some reason the WSPR website shows me operating from Latvia when in fact I am operating from CN87, Seattle. Both online profile and site properties profile show CN87 in the grid square field.

Pleased to spot G8TTI today on 2m!

Have only been using WSPR for a few days ... must think about a TX setup next :-)

My kit from QRP Labs is now complete but I just can't seem to squeeze enough RF out of it to reach beyond the confines of my village. !!! The antenna is a 6 band Hexbeam and is currently WSPRing with a TS990S @ 5w as the driving force. Back to the drawing board with the QRP Labs kit. :-(

As many of you know, I've been doing a pretty lousy job at keeping up with WSPRnet site maintenance because of life and job priorities. I keep meaning to do better, but it's time to get some help! I know there have been people offering to volunteer at various times, but I figured I would just put out a fresh request for help.
