Currently, I am working on a paper regarding propagation on 60 metres. Transmissions with JT mode were used to collect spots and create datasets. A valuable datasource is wsprnet.org, to which WSPR spots are uploaded and fed to a database. The data can be downloaded. In order to support the study, I developed a WSPR… Continue reading »
Today, I received my new QSL cards. I ran out of them quite some time ago and looking around on the internet, I found ON5UR Maxi-Print. Well, I can strongly recommend Max, ON5UR. I was really surprised by his quality of service. I sent a design which he could have printed “as is” but instead,… Continue reading »
Recently, I published an article with tips for more success on 60 metres. In the article, I said that it would be a good idea to switch from JT65 to to JT9, when a band is crowded. Because of the reduced bandwidth, more stations will fit into the available spectrum. On some bands it can… Continue reading »
On the site of the IARU region 1 monitoring system (“intruder watch”) one can find newsletters and reports about what is going on with regard to intruders and pirates. I am grateful for their effort. On page 2 of the December 2016 report, VK5EEE paints a picture that sent me shivers down my spine. Although… Continue reading »
One of the latest developments is a parser/analyser for the ALL.TXT files that WSJT-X and JTDX create. The ALL.TXT file contains all sent and received messages and as I wanted to have a tool to retrieve the data in a structured way, I decided to write a parser. It is made in Visual Studio 6….

Curiosity is one of my key drivers. Copying others is a dull game. Of course, sometimes, it is easier to make a copy than to create a bad lookalike, but in general, I prefer to explore unthreaded paths. That must be in my DNA:-) Thus, with the new 60 m allocation, these radio waves started… Continue reading »
I promised to report a comparison between JTDX and WSJT-X. Well, JTDX is the winner. I have been using is for several weeks now and I would not revert to WSJT-X.
In December 2015, I wrote an article with some tips regarding 60 metres. Here is a link to the article: 10 things to know for more success on 60 m I hope it helps you to improve your station.
Today, another good opening to Australia was recorded. During the last month, quite a number of openings occurred, showing that propagation from Europe to Australia is not as rare as I initially thought. In a number of cases, a peak is observed around 19:30 UTC. At that time, in Australia the sun is already above… Continue reading »
In my humble opinion, Joe Taylor, K1JT, is a true innovator for the amateur service. As a scientist, Joe received several notable awards. The amateur community should be grateful for his efforts and resulting advancement. Many amateurs may forget that our use of frequency spectrum is justified by experiments, with possible spin-off that benefits everyone…. Continue reading »
