I continue to test out Chinese manufacturing and assembly processes and still have a few 8-way Isolating-GPS Distribution boards (splitters) that I used as test cases available. These were entirely fa

Hi Arne, With interest I saw your developments on your grafana page, (wspr.live), where you try to visualize receiver performance comparisons. There is the experimental query page based (non-wsprdaemo

To get on the air with FST4W many options exist, the below gives some insight in the differences between RFZero and QDX. Both are smart choices to get on the air quickly and enjoy the benefits of tran

RPi4 2GB Buster update to v3.06 No FST4W decodes. I decided to try updating from 3.05 to 3.06. Git pull warned the wsprdaemon.conf file would be overwritten. I saved it but did not know how to proceed

Thanks for that alert Rick

Without mods it easily runs WD up to 4 wspr bands. Care has to be taken for more, perhaps add a small fan. It runs out of CPU at 6 maybe 7. A simple install works but the latest wsjt-x does not instal

I have been running a WSPR beacon with a 1x1 call sign for a local club event today, and I was delighted to see that wsprdaemon versions beginning with 3.0.5 will decode/upload this special type of ca

For users who want to install WD on a Pi4, due to a memory leak in the bash version 5.1.4 included in the Pi's current bullseye OS, you should instead be running the legacy buster OS. I have just chec

You may have seen the Inovato Quadra advertized for $29.95 Here's an quick eval using sysbench showing a little slower than a Pi4 QUADRA: root@inovato:/home/quadra# sysbench --num-threads=4 --test=cpu

Scroll down and you will see a list of tx and rx sites which have sent and/or received FST4W spots. I was surprised to see there are more tx stations (42) than rx stations (29). We need to fix that! h

Greetings y'all, I am now running my QDX on 20 and 40 usually early evening and after sunrise. I am using wsjt-x and a "surplus" raspi 3B as the easy way to get x-mitting FST4W. I did reduce the power

After I input "wdln" in the terminal window and then watching the terminal notes while my Raspberry pi 4b is running WD version 3.06 (latest one) makes me wonder, if Vers 3.06 really can run on a pi T
