FT8 has been around for some time now. It was adopted fast by the amateur radio community and although I do not know exact numbers, it is clear that FT8 is overtaking JT65. Let me first say that Franke and Taylor (FT) have done a tremendous job with the development of all weak signal modes… Continue reading »
A few days ago I worked PJ7/W9DR for a new entity on 6 metres. In the past, the entity was deleted because of the change in governmental structure. The contact with PJ7/W9DR was greatly appreciated! Looking W9DR up on QRZ.com led me to a nice video of his water cooled 6 metres amplifier, that runs… Continue reading »
After putting up the 5+5 element YU7EF 6/4 metre dual band antenna, I was curious how the new antenna performs. Although I realise that a real measurement requires quite a bit of effort, a simple comparison between the new antenna and an antenna with a more or less known performance at least gives a clue… Continue reading »
Last week, I put up a dual band antenna for 6 and 4 metres. It was difficult to decide what to build. Last year, I had separate antennas for both bands. Dual band antennas are attractive, because of lesser wind load and also because it leaves some room for other antennas. Another aspect was that… 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 »
Today, June 3, Peter JW7QIA, Svalbard Island was worked for a new one. Around 17:30 UTC, signals were coming in and not much later, I could add a new one. Here is a recording, just after I made the QSO. I forgot to switch on the recording… As you can hear, the signal was not… Continue reading »
I have been active on 50 MHz since 1978. It started with building a converter, because we were not allowed to transmit on 50 MHz in The Netherlands. At first, in the summer of 1978, only noise was observed. Television signals were the best I could get! But in the spring of 1979, I switched… Continue reading »
Have a look at some of the QSL cards received from stations who were permitted to transmit on 6 meters. I could only listen or talk back on 10 meters. At the time, most 6 meters stations listened around 28.885 MHz. Conditions were so good, that I could hear European stations via backscatter on 10… Continue reading »
When the 50 MHz permits were issued in The Netherlands in 1988, it was agreed with the authorities that we should report about the results of the experiments on 50 MHz.
The aim of the study was to correlate 6 meter openings to environmental properties, like solar flux, magnetic activity and the like.
