https://hobbyradio.se/ is now available. Terje Isberg (SK) is the developer behind DRM-Log Plotter software, and other DRM related analysis software. Terje passed away in 2022. He was a brilliant person, a polyglot (Swedish, German, English, Japanese), an incredible electrical engineer and an all-around great guy!
I had the great pleasure to spend several days in Terje's company in 2019 on a trip to Japan. One of my regrets was not being able to rescue his website - a must visit for radio and DRM enthusiasts.
I will help Mike by sending him files Terje sent me on a flash drive in 2021 - specifically to be able to maintain or rebuild his excellent website. I am so thankful to Mike for taking the time and energy to honor the memory and work of our friend Terje.
