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.

Ive been watching my results on 80 meters on the WSPR Challenge site.

For two days now Ive been lucky enough to hit the number 1 position, but this has caused me to question how much of this is due to my home location being electrically quiet ? Or is it the RF performance of the SDR equipment I'm currently running.

One thing is a fact however and that's my 80 meter antenna which is a simple 66 foot wire could be significantly improved.

After weeks of listening, i've finally sorted out an interface between my FT817 and my laptop. Living in a top floor flat and not having much room, I decided to try a random wire at the lowest power setting the FT817 would do (500mW). This random wire is a few metres long and is tuned using an MFJ 941E.

I'm amazed at the results, for what i thought would be terrible antenna, with a record so far of west coast Australia (around 14000KM!).

I upgraded my equipment to a direct conversion SDR: the Genesis G3020. The rig, when coupled with a very affordable SYBA SD-AUD20101 USB audio card, performs very well. I'm still "only" listening; I have been having great success with WSPR on 30m. The Genesis, with this audio card, is far more sensitive than the upconverted RTL w/LNA.

I am currently hopping between 15, 17 and 20m with 10mW into
my 3 Element steppIr set for Bi-Directional use
dir 90 and 180°.

After many months of working on this project a few minutes here and there, it's finally on 20 meters. Thanks to Zoltan Doczi, HA7DCD And TAPR for a fun little project.

Now I changed band from 30m to 20m with my Raspberry Pi (2B).
After a BPF and ATT there is 10mW going to my vertical.
Happy WhiSPeRing.

Hello,
looking at my wspr window I realized I'm the only one who received QM8RVM
Check it looking at me as a reporter on the online DB.

Is this possible?
Is anything wrong?

Hope someone could clarify!!

because my receiver in Curacao does not receive my signals,
i try to build a lineair amplifier with some more power.
This days i do the first exeperiments.
The antenna is a 20m. vertical with 20 m. long open feeding line.
(Like the old fashion Zepp antenna)

I find out that 4 mW on 30 meter will give less reports, in my case, and up till 1800 km.
With 17 mW it goes to 17000 km (VK)
So now I go to 10 mW with my Raspberry Pi on 30 meter into a 10 meter vertical.

The recent SSB Contest made me realize that fewer syllables are better, so I changed my call. It's the end of an era.
