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.

yesterday i installed WSPR 2.0
Today i was transmitting on 20 and 30 metres. Wow! with my magnetic loop and only 200 mWatts my signal was heard in Sweden and Norway. And with my Cobra dipole my 200 mW was heard in the middle East.

Let us see if this little thing works?

We are now in the season of super-DX Es openings on 6m when the band can open spectacularly across the Atlantic from Europe to the USA, the Caribbean, northern South America. WSPR could be a superb tool to help track fleeting openings over these very long paths, but we need more stations on 6m WSPR for this to be possible.

My WSPR station resumed operation at 0700 UTC on 4 June 2011 but very few spots were received on 7 MHz due to a high (S7) noise level. The RF interference source has been identified as a Dynex DX-HDEN10 hard drive enclosure. Its power adapter produces a high level broadband RF hash when plugged into AC power that saturates the HF spectrum in the home even with the unit's power switch in the "OFF" position. Ferrites placed on the cords were useless to reduce the interference.

According to WX-forecasts Summer will start tomorrow, so I took a head start
with some antenna construction. The intention is to have two fixed structures
that can be monitored on the same band by two separate receivers. The dual
dipole with anti-phase parallel elements (mentioned in a previous blog) is near
completion, and it will have about 3.5 dBd wideband rx-gain into the opposite
directions broadside to the dipoles. When mounted horizontally it will have zero
response toward the dipole ends as well as toward the zenith, or for signals


Well here I am after moving from the UK to ZL land, I have my antenna up, and surprisingly it works, I have a very old hustler 5btv, about a foot off the ground, surrounded by trees, the nearest being about 10 cms away and running up 80% of the antenna, a palm tree so the leaves get entangled in the antenna, 2m away is an all metal shed (x2) and my house has a metal roof too, being only 4m from the antenna, and being fed with 50m of coax around the edge of the garden, I am surprised I hear anything or anything hears me.

Very cool...half a watt gets me across the continent!

Probably not on 6m ...

Last night I tuned into the WSPR frequency on Top Band.
I was using a 20m length of wire, my antenna is only about 6 metres above the ground and the background noise was a constant S8....... I wasn't expecting to receive much with this set up.....BUT!!
Despite this I managed to receive the following stations:

G4BOO and PA0O.

Really pleased with this as I wasn't expecting any stations considering my meagre antenna.



I thought why not test this WSPR proper....I've decided to give Top band a listen.

I'm only using an endfed antenna with a 9:1 homemade balun attached.

The endfed is going to be 20 metres long.

I will be QRV between 9.00pm and 10.00pm most nights..

I wonder if I'll receive any reports?....fingers crossed

73 Mark

My whole station is solar powered with 22 panels giving about 4 KW max

My first outing on Wisper proved to be very sucssesfull.

On 30m I'm certinatly being heard with about a Watt from the vertical on the back of house, and some stations are evening making it through the horrible QRM I have (I live in the middle of a town!)

Back to 10m for daytime, and see if we can improve on yesterday's SpE results.


Sorry these spots are wrong:

Anyone Reading this, I'm NEW to WSPR and run all Mac's here Except 1 Dedicated AR-Cluster Node machine.
Just Trying new Modes out for OSX.

Hi !

This weekend i transmit with 10 Milliwatt on 20-Meter and try to reach Leigh (VK2KRR) in New South Wales.

Hoping for a few more Sunspots ...

Best Dx so far:

Have Fun, Oliver


In the last week or so I have been experimenting with WSPR 1.0 on an old Compaq Armada E500 Pentium III 600mhz laptop with 128mb of RAM and Windows 98SE solely in receive mode. Although I thought the processor might struggle, to date it has performed very well. Saying that when there are a few stations to decode it can take 30-45sec after the last 2min transmission segment has ended for it to show any results but it hasn't crashed yet.
