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.

Hi. I'm building a RPi3 based 160-2m automated WSPR TX/RX station. Some parts of this may be of interest to others. If that is the case I will post updates as the work progresses.

The project aims are as follows:

Have been wanting to try WSPR for a while and finally got some time to set up a Raspberry Pi board with a TAPR WSPR-Pi hat set up. Running my first test today, I am getting many far away reports on my signal which is very exciting.

I have been active on WSPR for a couple years, but have just recently found the time to sit down and do it right. My shack is in the mountains of Colorado, USA, at an elevation of 8,064 feet above sea level. I have lately been using a Yaesu FT-890 as my WSPR rig, since I can adjust the output power down to a QRP level. I have recently also discovered that the antenna I rigged up to try to communicate locally on HF -- a one mile barbed wire fence, fed with about 600 feet of old 4 pair armored telephone cable that was left here on the property some 22 years ago.

Online on six bands (rx only) - 1.8, 3.5, 7, 10, 14 and 18 MHz

Hardware: Raspberry PI 3 model B + 2xSTM32F373 boards + six receivers (with SI5351 DDS).
Documentation is here: https://github.com/sergz72/wspr_modules

Begin at 21.02.2017 / 8AM local time / 0700 UTC
with 5 Band KW wire
Tx 200mW

Using 100mW on 20m through the EFLW today.

How exciting! VK4YB was heard here in Pleasanton, CA at 475.600 on 2017-02-08 and 2017-02-09.
The sdrplay and boniprobe are working really well, hearing Roger over 11425 km of ocean.
The best signal was -27db at 10:20 on 2017-02-08 at about 2:10AM local or 10:20GMT.

Hello all! We make a web page to describe the design of our stand-alone option WSPR beacon. Description in Russian, please use a translator onlain.

We currently have 2 WebSDR receivers running in Grimsby and Cleethorpes useing rtl dongles,they cover 10mtr through to 23cms we thought it would be good to get them wspr'ing, so initially we have 10mtr operational and running sometimes we have a spot upload issue due to network bandwidth on our system links can be found at https://sites.google.com/site/g1hznhamradio/ Look on 10 for G1HZN/R which runs 24/7

Today I modified my 6-band homemade SDR receiver to get a sampling clock from an OCXO. I also put WSPR-15 decoder running on 160 meters to see if there's any activity. At least the frequency stability should be good enough now.

The 20m mobile Am-Pro whip has arrived through the post, the next WSPR test will be to see how well it radiates.
Not expecting much but it will be interesting to see what is possible.

I've just finished work on my 200mW WSPR-beacon based on Arduino/AD9850 DDS/HD44780 LCD. All details like source-code, C-libraries, antenna design, schematics etc. can be downloaded from here:

While there are things I like about each of the three software packages available, SDRuno, HDSDR, and Console V3, I find myself constantly going back to Console V3. SDRuno is very, very, complex and I don't feel handles the digital signal as well as Console. To be fair, I am in a very high QRN environment and it seems that the noise is "tricking" the threshold points and constantly making the overall gain reduction jump up and down.
