After I decided to reduce hosting costs and generally bring my web applications from the cloud to my home, I needed an energy-saving server on which I could install Proxmox.

This page serves me to record which Doom WADs I have already played and what my verdict is on them.

I’ve recently moved away from GZDoom and picked Crispy Doom as my main Doom source port.

This website is dedicated to amateur radio, electronic tinkering, cybersecurity, retro computing, homelab building and other (mostly technical) topics.

This is not an ordinary blog post and it will not interest most readers.

So far I have made all my 3D designs with Tinkercad.

After I had to take down my M0PLK Delta Loop, it was time to experiment with new antennas.

I have firmly resolved to worry less about awards and QSLs in general.

Recently, I purchased the S9 Level Generator Kit from Box73.de.

For several weeks, we encountered issues with our AEG Lavatherm Protex Plus dryer (Model: T5.5IH, Type: TC12H6MHP, purchased in 2014).

Recently, I encountered a weird issue where one of my four WiFi access points, a Mikrotik wAP AC, stopped functioning correctly despite being powered on.

If you’re a ham and have ever been frustrated by local QRM (man-made noise), you know how devastating it can be.

I’m not sure if this will help anyone, but it will at least serve as documentation in case I have to re-set the TX audio settings on my FT-710.

Update 2024/12/23: I’ve managed to kill the ATU a second time and learned some more.

Since I got my amateur radio licence in 2019, I have set up and operated my radio in a small boiler room in the basement.

This afternoon I visited the Classic Computing 2024.

To spread the word about amateur radio, I’ve submitted my Declaration of Love to Amateur Radio as an article for the 2600: The Hacker Quarterly magazine.

I’ve already built some ATU-100 automatic antenna tuners in the past: One was a build for QRO and one for QRP with only 5 windings on the binocular transformer and adaptions to the original firmware.

After I’ve built the QubeDX for the higher bands (20 to 10m) and it’s little brother, the QubeDX S for the lower bands, I’ve realized that it would make more sense to combine both cubes into one.

After I’ve built the QubeDX for the higher bands (20 to 10m) and therefore for the M0PLK Delta Loop antenna, I now wanted to build a second one, mostly for 40m.

During our last holidays, we visited the “Amrumbank” lightship in Emden, northern Germany.

I’ve written the following small Python script to migrate a Bear Blog to Hugo: import csv import os with open('post_exports.csv') as csv_file: csv_reader = csv.reader(csv_file, delimiter=',') os.makedirs(".

Had a very nice and special POTA activation of DE-0094 Niedersächsisches Wattenmeer National Park: Conditions were rough but I’ve managed to get 16 stations into my log, including two from the Azores.

The following instructions describe how to configure Fldigi for operation with the QRP Labs QDX transceiver on Debian Linux 12 / Raspberry Pi OS (64bit).

On this page I am continuously recording all the findings that I have been able to collect in connection with the QDX Transceiver Rev 6 from QRP Labs.

(the frame is actually dead straight, the distortion comes from the camera) This article is about the implementation of the idea of building a (decorative) QRP radio for digi mode operation that can be operated remotely via Wi-Fi.

Besides amateur radio, I have another passion: Doom.

I’m a big fan of Quisk, the SDR software I use for my Hermes Lite 2 SDR transceiver, but I am not the biggest fan of the available color schemes.

When I started amateur radio in 2019, I initially only considered FT8 and FT4, as it is a very simple and straightforward way to get into the hobby - also because I still was very mic shy.

After far too long, I’ve finally managed to get Fldigi and Quisk to work together to finally do digi modes like Olivia.

This post is not a detailed guide to buying a Motorola radio but rather a list of things that I think you as a ham should know about before buying a used device.

It was time for me to get out my HF Signals uBitx v6 again and use it for stationary shortwave radio operation.

The Matrix HAM Radio Space, which which is hosted and administered by M0AWS, is a slowly but steadily growing community of radio amateurs who are actively exchanging ideas and information via the Matrix chat network.

The current drama with the Logbook of the World (LoTW) and its prolonged outage has made me think about the topic of QSLing and why it is or seems to be important to me.

After I recently discovered APRS for myself, I realized that I could not establish radio contact with the surrounding APRS digipeaters in and around the house with the HT.

In order to reduce my travelling luggage, to be able to charge my Retevis RT3S even in the event of a power failure and basically to standardise the charging of devices, I have been looking around for a suitable solution.

Some time ago I bought a second-hand Xiegu X5105, which is 100% functional, but had a small flaw.

Earlier this month I published a blog post about the Hardrock-50 Widget for Quisk written by Harald, OE6HKE.

This article tries to document the essential steps to achieve the following on a fresh OpenBSD 7.4 install: Serve static files via HTTP(S) Host a Gitea instance via HTTPS Host a PHP based FreshRSS instance via HTTP(S) Install and maintain Let’s Encrypt ce…

My shortwave station consists of a Hermes Lite 2 SDR transceiver, a Hardrock-50 power amplifier and the marvellous SDR software Quisk by James Ahlstrom.

I’ve recently built a Remote Control for the Hy-Gain AR-500X Antenna Rotator which works nicely but requires me to look up the desired heading for a specific station in Cloudlog, go to the remote control web application, determine the best memory channel…

The following comparison between a Hustler 5-BTV vertical antenna, a Cobweb antenna and an M0PLK Delta Loop is not a scientific treatise, but rather my personal experience.

The project described here attempts to solve the following problem: an antenna is to be rotated remotely using a Hy-Gain AR-500X antenna rotor.

I’m actually very happy with my Cobweb antenna for the shortwave bands from 20-10m.

The strange thing about me and my buying behavior when it comes to computers is that I’m stingy.

I thought is about time to express my gratitude and admiration for the SDF Public Access UNIX System.

Today I had the opportunity to be the first to successfully activate the “Cuxhavener Küstenheiden National Park” (DA-0264).

I’ve tried to read and understand several books on the propagation of radio waves, but they were all too academic for me.
