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.

WSPR-challenge

PA3FYM WSPR-challenge receiverThere 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.

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.
