Latest situation of the WSPR-RX

A while ago I did build my first 30m WSPR-RX to participate in the WSPR-challenge. I must admit it is very addictive! It did not took long before I was building my second WSPR-RX. This time a little bigger since the first one was too much miniature. Also I wanted to add some tweaks.

RaspberryPi-3

RaspberryPi-3

My latest acquisition to the shack is a RaspberryPi-3. A great birthday gift to get! I already owned two RaspberryPi-1’s and one RaspberryPi-2. One of the RaspberryPi-1’s is doing a great job to put out the telemetry of my weather station with Xastir. I wanted the RaspberryPi-3 put to work as a WSPR-decoder as extension on my latest project: the 30m WSPR-RX. Still working on tweaks for the RX though.

psk31waterfall.jpg~originalWhile on our holiday in Belgium propagation forced me to use digimode (PSK). It’s funny when you are in a relaxing mood like on holiday and you spend some time setting up PSK again, it’s actually a great way making QSO’s. I really enjoy watching the waterfall for signals and looking how other ham’s programmed their macro’s. Many inspire me to fine tune my macro’s a little more. Of course I plug this blog in my long-reply-macro πŸ˜‰ Great way to propagate the formula.

I read my fellow ham’s are also busy in digimode: PE4BAS in WSJT-X (which is on my to-do-list too) and VE3WDM.

It sure is fun doing some PSK or other digimode when propagation is low. Morse code is a mode which is also very suitable for low propagation. A little harder to learn though. We are heading for another low in the 11 year sun-spot-cycle. I guess that means we have to wait at least for 5 or 6 years for new really good propagation on the bands. Looks like we have to use CW and digimodes for a while.
