Content preview: Hi all, Does someone have an explanation for this: I just observed a something on my LF grabber: There are some traces in my LF wideband overview captures, e.g. https://dl.dropboxusercontent.com/u/19882028/MF/LFwide.jpg These periodic traces are Intermods coming from my local MF WSPR transmissions which do slightly overload the LF/MF antenna front end. One of these traces ( ~ 137.6 kHz) slowly disappears arround 4 UTC, so maybe it has to do with HGA22, so this is not unusual. However the other one, arround 136.3 kHz disappeared instantly arround 9:30 UTC. DCF, HGA and my own WSPR transmission is still on air though.
