Regular readers of this blog know that noise (interference, to be correct) from various sources is my most prominent nuisance. A few weeks ago, I stayed for a weekend on a rural location in France and took my IC706 and antenna with me. A wire antenna was put up, using a tall tree and two… Continue reading »
The last few days, conditions on 6 and 4 metres were quite good. Even with my modest station, some nice DX was worked on 6. Back in 1989, I became rather frustrated because I had ‘half a QSO’ in CW with CO2KK. He unfortunately took my call as PA2HJH instead of PA2HJS and I was… Continue reading »
This article drew my attention. Another story about “Megahertz” wireless power transfer. If something is going to kill radio communications, this is spot on: Wireless power transfer Old school efficiency There were times we had trains. Electric trains. In The Netherlands, most railway lines use electricity to convey power to the locomotives (like this one… Continue reading »
Today, I stumbled upon a write-up of Joe Taylor, K1JT about developing a version of FT8, intended to be used by DXpeditions. In spite of the fact, that I do not favour FT8, especially because it takes out the lower tier of the signal to noise range, I consider this an interesting and valuable development….

It is quite obvious that the internet helps to spread news very fast and thus, a real FT8 explosion took place. On busy moments there is a myriad of stations and it is impressive to watch how good the WSJT-X software decodes the whole bunch every 15 seconds. Hats off for the developers! The FT8… 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 »
Recently, I received a note that Chines radio modems are used for telemetry. The note states that these transceivers are operating on our 2 metre band between 144 and 146 MHz. More details are expected. Along with the note, a link was sent with a URL to a Chinese company, selling these transceivers. They operate… Continue reading »
These days, we often hear the abbreviation IoT, which refers to the Internet of Things. For me, the abbreviation triggered the term “Interference of Things”. We live in an age of ever growing numbers of electronic devices, that all have one thing in common: they need power and thus can be the source of unwanted… Continue reading »
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 »
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 »
