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 »
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 »
The story continues Yesterday, Nov. 13th, the propagation to VK was weak. Just a few spots from some European stations were reported. Alan, VK7BO mailed me that he would leave his receiver on, when possible. That encouraged me to continue the observations. Nov. 14th, I was checking to see if a free message with “TST… Continue reading »
The 12th November 2016, another opening to VK7BO occurred. As I wanted to analyse the openings, I transmitted every other minute, mostly CQ’ing and making some QSO’s just as well. All spots were visible on hamspots.net and to be on the safe side, I took notes in my little booklet, that has a lot of… Continue reading »
Today, after returning home, I checked hamspots.net and spots from VK7BO were again there, so I decided to start sending CQ’s, hoping to get a number of samples, to compare with yesterday. The opening peaked -7 dB at best, but this time, a number of -7’s were recorded. Unfortunately, hamspots only showed the last 250… 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!
