Just finished two weeks vacation up north in JP66, and accidentally found a nearby summit that never had been activated before. Åkvikfjellet, LA/HE-475, was successfully activated with 27 QSOs. I could have done many more, but for those of you who have met me in person will now nod understandingly, knowing that I cannot function …
Picture a Norwegian guy that feels 15°C is a comfortable summer temperature, and starts sweating uncontrollably and complain when it gets above 20°C. Now, place this character in a humid environment, say, for example Germany, and make it 40°C instead. Just for the heck of it, let's also disable the AC in his hotel room. …
In the northern part of Norway we don't have the luxury of 24/7 6m openings (I'm looking at you, Central Europe!) so whenever the allmighty RF gods sprinkle us with dopamine inducing sporadics, we need to be prepared and on the alert. So, therefore, my friend Kajetan (LA8WJA) and I teamed up to build each …
Here are a few pictures from the DXpedition to Bouvet Island in March, 2026. I originally planned to add a written story to the images, but I'll let the pictures speak for themselves this time. Bouvet is breathtaking. Brutal. Merciless. Pictures are available on this page. Bon voyage. From all of us - thank you …
Before I start posting pictures from the 3YØK DXpedition, let's take a short break and discuss a few things. Yes, you should read this too, even though it may or may not concern you. Quite many operators out there suffer from a condition called "silicae vaginalis", more commonly known as having sand in their vaginas. …
3YØK is QRT. We've been to Hell and back, trust me, you have no idea. Before you get all excited, this is not a post pictures. It will come later, so consider this a teaser. Ok, fine, you can have one: 102k+ QSOs in the log. On the air 24/7, with the exceptions of fuelling …
It has been a long wait, but the time has finally come. I'm hours away from starting the journey towards Cape Town to meet up with the rest of the team, and begin the adventure 3YØK DXpedition to Bouvet Island. Clothes are vacuum sealed and ready. Bags are ready, and all items accounted for. Home …
I had to work my way around a couple of unexpected obstacles. The transistor I used as a "pre-amp" did not perform well enough to work on 17m. The rise and fall time was way too slow, barely being able to perform at 630m / 475kHz. Indeed, that was my target frequency, but being expert …
Results from testing the power amplifier were both uplifting and disappointing. Let's get straight to it. Let's take the bad news first. The current design use a small NPN transistor to amplify the Si5351's output signal from a unloaded 3.3V to 13.8V DC to allow the FQP13N10 mosfet to switch as intended. For frequencies higher …
...to be tested! Hah! You just got click-baited! But keep reading, though. It might get better down the line. Let's have a look at the current state of things. Right off the bat, and to be frank, no real schematics exist yet. Apart from a few sketches in my notebook, it's more or less built …
