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.

One of my better reception reports.
2014-09-19 07:42 KQ2RP 14.097162 -27 1 FN20 0.1W VK5MR PF96lh 16927km
antenna = vertical W3EDP

Interesting contact from transmitter K9AN to receiver KD6RF, 10 Meters, on 2014-09-18 13:06 ---->

2014-09-18 13:06 K9AN 28.126167 -27 -1 EN50wc 2 KD6RF EM22 1050 218

Propagation on CONUS for some time before and after the above time was nil - I saw only US/Europe contacts for hours before and after the above spot time.

In addition, K9AN shows doppler 3 Hz low in frequency, and with a -1 drift. K9AN is, I believe, GPS locked, and KD6RF is rubidium locked, so the frequencies are likely accurate.

The old TS120S based WSPR system is now all good. The frequency drift has been stopped with the x-lock modification and now with the addition of Dimension 4 time lock to the laptop, I have a very good system.

I like this whisper stuff! I have a small screwdriver type ferrite/ ali core tuned whip mounted on the side of my shack in amongst the trees , brill!

Recently loaded up xubuntu 14.04 and successfully compiled WSPR thanks to M1GEO's webpage (thanks George!)

Would anyone be interested in an assembly service for the Ultimate 3 kit, produced by Hans G0UPL? This is an excellent compact multiband capable WSPR transmitter/beacon (as well as many other digital modes) and can be purchased from QRSSLabs with additional options.

Mike told me he would be there this weekend for the recovery of activity on 160m "across the pond". Well he has not missed his appointment. During the night, it was heard by G8DYK, G3ZJG and I F59706. He heard PA0O and especially G3ZJG to score a rare and first 2way across the pond of this new season.
Also to note, Bob K4RCG at my sunrise, heard with SNR=-15. The highest snr since the development of its 160/80m antenna.
A month after the start of the new season and thanks to Mike, my score for my Rx Challenge is up to 9.

Thanks to all and GL, Patrick

Simple universal interface with an internal sound card for digital modes for FT-897.

Attached picture shows a screenshot of reception and decode yesterday of two stations in the presence of multiple aircraft doppler and reflections. A particularly severe time period was 1542 (4th block from left).

Reception conditions:- 5 ele. H. pol. Yagi antenna beaming 330 deg, fairly optimal for both stations.
Heathrow airport is approx. 20km away at approx. 50 deg. az. (so off the side of the beam).

Didn't have presence of mind though to look at AirScout software to see how busy traffic was - one for next time!

Test on 474.2kHz with ultimate-3 200mW L-Antenna with Variometer

Today on 40, I have decoded two spots for DL2XL:
1232 4 -0.8 7.040121 0 DL2XL JO31 23
1232 -8 -0.7 7.040137 0 DL2XL JN39 23
My first thought was it reflected some kind of spurious TX, but the geographic locators are different. Only one coincides with the QRZ entry. Maybe DL2XL can help solve the mystery.

I've noticed for some time now that DC4LC is continually mis-reporting the
bands of his spots.

My 10Mhz TX is being reported as being on 7Mhz and 14Mhz.

Obviously these false spots are going to be happening to everyone he received on 10Mhz !

I don't have his contact details, but of DC4LC is reading this, can you please correct
your equipment.

Thank you.

Great to see the first active night of the new season to NA stations. Around 50 dx spots across the pond in the wspr data base between 01:46z and 05:10z and three NA stations heard in EU : KJ4YBS, K9PAW and K4RCG. We can congratulate Bob (K4RCG) for the new and effective 160m antenna.
W3PM, K9AN and K9YWO were "on air" but have not been heard.
I'm naturally optimistic for the rest of the season and the running score of my Challenge. Good luck to all, 73

Hi All,

I have written a WSPR tutorial to assist beginner WSPR operators in being able to get the most out their WSPR stations.

Many operators, including myself, face a bewildering array of features and subtleties which define the WSPR system as a whole. This guide hopes to help beginners overcome some of the difficulties of WSPR and find their feet as operators.

This was originally focused at the ZS (South Africa) region.

This is a work in progress and many people have assisted in proof-reading the information.

Feedback is always appreciated.

I'll be listening on 474 KHz tonight using WSPR-15 mode in case any of the Lowfers are interested. Gear is a 43 Foot vertical, Funcube Pro+ Dongle, and Clifton Labs low pass filter designed to cut off local BCB signals.

Anyone have any idea where the wsprx (the experimental slow 15 minute mode) reports end up?

I'm sitting on 160m running wspr-x at 1 watt at the moment (18:00 UTC) but I can't see where any maps or other supporting information like who else is on is to be found.

Or am I on my own? :-)

My VFO stabiliser is now working and has locked the old TS120S VFO and cured it's until now temperature related frequency drifts. It worked very well at stabilising the VFO initially but because of over compensation the receiver would not decode WSPR signals. However after reducing the varactor to VFO coupling, all is now working very well. I am very pleased with the X-Lock from Cumbria designs.
