This is a baseband receiver using direct conversion, located in a rural area of the German uplands (Sauerland).
Currently, I am running the WebSDR using a PA0RDT MiniWhip instead of the homebrew etherprobe. Please note that the bias tee is limiting the response to frequencies higher than 10 kHz.
A robotic lawn mower is on duty during growing season causing some RFI while running at daytime.

The receiver is part of the PA3FWM WebSDR project and operated by Sabine, DL1DBC.

*** Expect radio interference by a robot lawn mower today between 11:00 UTC and 15:00 UTC
