2016-01-14 Searching for radio interference 3 years ago
One of the reasons for shutting down the homeserver was that I have a constant heavy noise on several amateur radio bands, at least on 10/20/40 meters. The noise is always at level S7/S8. I wanted to eliminate the server / UPS / network switch as possible source of the noise. Rebooting the server also helped reset the video mode back to 80x50 so the earlier problem with interference caused by the video mode is now gone, even with the video cable plugged in. But there is still a lot of other noise left.
