Another radio active year has passed. 2016 was a pretty good year as far as my blog involved. My stats doubled since 2015! It’s a shame I moved my blog so many times since 2001, I don’t have stats from the beginning. But hey, the radio hobby is all about experiments.

How cool is it for a ham to temporarily change your call to aeronautical mobile (PA1JIM/AM) during a once in your lifetime experience? Even more so when you can do that from an airliner at 38000 feet up in the air? The other day my good buddy and associate at Pepper IT-solutions VliegPiet made me an offer I could not refuse: to join him as captain in the cockpit of a Boeing 737 on a return flight from Amsterdam Schiphol Airport to Sevilla, Spain.

The Kenwood TM-742E
A while back I bought a second hand radio: the Kenwood TM-742E. A great radio with 2m, 70cm and 23cm module!
The man who sold it is a heavy smoker, so I had to clean the rig intensively. But after doing a good job the radio is like brand new. No scratch on it.

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.

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.

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.

23cm @ PA1JIM
There wasn’t any 23cm ground plane antenna yet on the roof @ PA1JIM headquarters, only the double quad antenna. But the quad is pointing towards the PI6NOS-repeater.
Therefor it was impossible for me to open the 23cm repeaters in Den Haag and Rotterdam. Furthermore I wasn’t fully satisfied about my Diamond X200N for 2m and 70cm. It worked, but not beautifully.
