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….

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 »
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 »
Nov 10th, 2016 and the following morning brought two presents, that I really appreciate. Reports from VK7BO appeared on Hamspots.net showing reception of European stations on 60 meters. I decided to put out some CQ’s to see if my signal arrived. Well it did! In the past, VK7BO received my JT65 signal, which was a… Continue reading »
Another remarkable surprise reception of my JT65 signals was noticed on Sep, 9th, 2016. VP8ALJ apparently had a receiver running on 60 meters and copied my signal with -21 dB. Not only a remarkable distance (nearly 13,000 km) but also showing what 60 meters has to offer. Thanks to VP8ALJ for his effort!
