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 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.

Operating from Wailea, Maui, 40 meters, transmit mode only.
Antenna is ATAS 25 on second floor patio.

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.

It look like that my vertical works much better than my horizontal wire.
Becouse of that I now make 6 db less power.
So for now: Raspberrry Pi with 4 mW in a 10 meter long vertical on 30 meter.

In previous post you can see that I was using a wireantenna of 10 meter long horizontal to the backyard.
Now I use a vertical of 10 meter with a CG-3000 antennatuner in the backyard.
The rest, a Raspberry Pi (2B), the BPF and the output of 17 mW is the same.
Lets see if I can find the difference.

Today is my first day on WSPR - trying 10.1387 plus audio.
Anyone see me? Thanks - EL98is
in Florida, USA

I am now on wspr 30,20,17,12,10 metres with LF and 50MHz being added soon
Also QRSS on 30m
Max power is 1 watt
