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. Continue reading →
There is buzzing a new phenomenon at PI4RCG (our local HAM club): the WSPR-challenge. One prominent club member, Remco PA3FYM, founded this WSPR-challenge with Richard PE1ITR. Essentially they download the whole WSPR-spot-database once every night and parse it in a top 50. The result changes per day. This challenge only consist of reported spots to wsprnet.org. So you can sneak peak at wsprnet.org site to see your uniques. Since wsprnet.org only logs your reported spots, this challenge is actually a RX-only contest. Continue reading →
Last week Remco PA3FYM did a keynote at the club about WSPR. Remco explained a lot about Signal to Noise Ratio (SNR) and the theory behind WSPR.
He told the idea behind the WSPR-challenge which he and Rob PE1ITR organized.
As always with good quality keynotes, this one tickles me to anticipate in this WSPR-challenge. But I have to be careful not to have too many things on my agenda. With my daily Morse training this is not a good time for another challenge.
Nonetheless a great keynote and many thanks to Remco. Another item on my bucket list 😉
