Blog
Because I love playing chess (although just being a average player), I added a section about chess to this website.
As a hamradio homebrewer I often use my NanoVNA to measure filters, antennas and crystals. But a NanoVNA is much more than that, you can also measure components with it.

Now also availible as complete or build kit. Check out this ForSale page.
What's on my hamradio bookshelf? After cleaning the shack I thought about adding a article to this blog on which book i have and use in the shack.
After a few weeks I decided to setup the dish temporary in my backyard and made some cables to wire every thing up.. The original setup had a off focus placed 4.5 turn helix which was ok, but didn't give the expected punch and the signals where a little bit weak in SSB on the QO-100. Other operators told me that the signal was readable but not that strong. So that was one thing to improve and the idea a of a new Helix feed was born.

A few months ago I ordered a ATU100 kit from China (without a case), and on a rainy weekend I decided to build it together. This ATU is equipped with a 1.3" OLEDd display and one thing I hate about these displays is that you almost can't install them without damaging the glass. Thinking about it, I decided that I need a 3D printable frame which puts all the mechanic stress on the PCB instead on the glass . . . Continue reading . . .
Today I installed one the Electron Volt Limited AGC's in my QCX-mini and it works like a charm.
