WSPR viewer
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 »
Paper QSL cards? Check ON5UR!
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 »
6T9 (promoting JT9)
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 »
Quickly losing ham bands?
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 »
JT Analyzer
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….

TenTec 229 tuner modification
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 »
JTDX compared
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.
10 things to know for more success on 60 m
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.
Propagation to VK continues
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 »
