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 am always amazed by the diversity of the propagation on 160m and sometimes concentration in a small area.
This morning at sunrise, it was "K9 only" for a short opening of 18 minutes with at the end my 20th NA stations of my season (K9YWO):
2014-12-08 07:32 K9AN 1.838170 -24 0 EN50wc 2 F59706 JN07th 6849 50
2014-12-08 07:20 K9PAW 1.838190 -28 0 EN61ar 1 F59706 JN07th 6723 51

I have just started transmitting again on 630m. However, when I was searching the database I couldn't find some spots from just over a week ago. I posted (as WR6J) this spot:

Coming into the summer months now for the southern hemisphere, anyone in Australia or New Zealand with the equipment should give 6m or 2m WSPR a go.
6m WSPR can be particularly rewarding with the sporadic E MUF coming up. Would be also good to get a little bit more activity from our northern neighbours and up to Japan in this regard also with TEP paths.

Remember that the E MUF can also rise to above the 2m band, so running a simple station even with a 1/4 wave vertical on 2m WSPR can produce results, probably from now till about the end of January.

Haven,t blogged for a while - just updated my info to new tranceiver.

Also periodically using a 10mW WSPR transmitter on 20 at work QTH using ZL3RNL and running on a Raspberry Pi - great for aligning my antennas at home QTH 10km away.

I use my Raspberry Pi to generate the wspr signal on 20m. After a filter, it goes into a (poor working) dipole directly on the wall (well, it is Munich, I have no chance for a good antenna)
After 3 days of experiment I was heard for the first time. At 08:00 UTC 1000km to Denmark. Not bad!

10 meters to VK, and I was using my off-center-fed dipole. 100 mW still amazes me. 153,335 km/watt = 95,834 miles per watt. Of course, this assumes short path to VK, not really sure how to tell if it was LP or not. VOACAP lines up nicely with short path at that time, and that's good enough for me!

Not an amateur op, so I'm in the receive mode on WSPR providing "spots" for the site. I was a "Lowfer" beacon op back in the late '80's- early '90's, but now I'm content to be in the rx mode to see what I can hear under the noise level.

Hello every one ,
for more info look @ my site in qrz

I am finally active on 630m using my new part 5 callsign WH2XNA. I am starting with my Ultimate3 kit running barefoot. Estimated ERP is 10mW and I am only able to transmit.

Thanks to N6KOG for being my first spot (ground wave I presume):

2014-11-29 05:32 WH2XNA 0.475710 -26 0 CM97 0.01 N6KOG CM97gs 49 312

I am really at CM97ag (Los Gatos, CA - near San Jose). I will be working on matching my amplifier so that I will be able to increase my ERP to about 0.5W



I've turned on my WSPR beacon on 80m tonight November 28th.
Power is 3W into a low above ground OCF dipole.

Hi everyone,

The first WSPR TX App for Android is available in the Google Store.

The WSPR Beacon App is made to send WSPR signals using your Android smartphone/tablet as a signal source. All you have to do is couple the audio out with the audio in of your rig (and set it to VOX).

All you have to do is:

I've put a beacon up using the ultimate3 kit with a Ublox7 GPS to condition the frequency.
All seems to work ok into a low down windom.

I've set it to 14.097.165 , good strong satellite fix so that should be right.

I'm now not sure how accurate it is though - the spots so far show a huge amount of variation.

I guess I could be right and everyone else wrong!

QRV with Raspberry PI headless w/o LPF on 20m. Just a long wire in GPIO as antenna. Let me know if anyone RX me.


Thanks to the hundreds of people who have downloaded my WsprNet Viewer program from the Google/Android play store:
The next iteration will include Google maps capability to display great circle propagation, markers, and beacon heat maps. See some screen shots (using Chrome or Internet Explorer) here:

I've managed to get my attic based WSPR PI beacon back online, still just QRV on 30m but if all goes well I should soon be adding some more bands.
