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.

after a busy day.... are on air on 30 meter.... ts 570 5 watt and fd4 by fritzel beaming est/west..... good luck and happy sunday for tomorrow...

Sorry to spam this here, but I've not been able to make direct contact.
Once or twice each day your 630m transmission is faulty. Here's an example:

Seems to be on 100% TX and 0dBm on 80m this evening.

Maybe time to read the manual?

hello i'm in3izq ... i return on wspr after many...
are active with ts2000 and vertical antenna on 30 meter with 5 watt.
good luck and good dx from italy de in3izq danilo bye

I noted in the day that Rick (VK6XT) was very active to the USA for 2 hours after its sunset (11:16z) with 45 dx spots in the wspr database. He was spotted by 6 NA stations at the same time (12:10z).
It was unlikely to imagine a similar event for Europe at Rick sunrise (20:53z). To the best of my knowledge there is no precedent.
Rick is firstly spotted by John (G8DYK) at 18:52z then PA1RZ, OZ7IT, F5OIH, F59706, G3WPD, ON7KO, G4BOO and the latest OH8ALT/P at 21:06Z for a total of 61 dx spots.

In Japan, 6m band plan will be changed from January 5.
Narrow band data communication will be OK between 50.2 and 51.0MHz.

I have been pondering on the subject of wspr for a little while now and still not completely up to date with the various 'How To's',
I will no doubt rely heavily on the great volume of experience and understanding of the members in this group. I apologise in andvance if I apprear ignorant to much but I am returning to this hobby after quite a time of absence.

If anyone is interested in using the QRP Labs low pass filter relay board with WsprryPi then I've forked the code here to support it:

Example band hopping command line:

./wspr -s -o -r -l12345 M0XDK IO92 10 80m 40m 30m 20m 12m

Hi, the new version WSPR-AXE-CW is a standalone beacon kit (or we can assemble for a fee) for either the 30M, 20M, or 10M band (monoband). It features easy assembly and no programming on the user's part (comes with a changeable chip for call, grid square). The output power is 1W on the lower HF bands and 0.5W on 10M. It is high efficiency and low current draw. Here is the link to the preliminary construction manual:

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
2014-12-08 07:14 K9YWO 1.838181 -26 0 EN61fn 1 F59706 JN07th 6708 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:

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

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!
