Bouvet Island: photos

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 in the gallery. Bon voyage. From all of us – thank you…

Intermission

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 QRT, but I’m alive

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…

Checklist done. Here we go.

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…

PA redesigned, tested

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…

PA considerations, redesign

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…
