Last weekend, New Zealand issued permissions on a trial basis to operate on 60 metres. That was very good news, first of all for the ZL ops who had been waiting for this opportunity for a very long time after the WRC-15 results came into force January 2017. It is hoped that this will lead… Continue reading »
FT8 has been around for some time now. It was adopted fast by the amateur radio community and it is clear that FT8 overtook JT65 quickly. But is it an improvement? It has to be said that Franke and Taylor (FT) have done a tremendous job with the development of various weak signal modes and… Continue reading »
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 »
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….

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 »
Celebrating one year of 60 m in The Netherlands with a surprise from Antarctica!
Both 15 and 16 November 2016 had good openings again. Data of 6 openings is gathered now. Below is a graph of these 6 openings, again with SNR against UTC. The differences are remarkable, especially at the beginning of the opening, but towards the end, the pattern is more “in sync”. I again used about… Continue reading »
