RF energy within its range, it can’t distinguish
between different frequencies, protocols, or
modulation types. In other words, it can’t tell a
ham radio transceiver from a Bluetooth headset.
It only determines the overall level of RF energy in
much the same way that an audio decibel meter
tells you the sound level, but doesn’t tell you
anything about which frequencies, such as bass
or treble, are producing it.
Unless you’re in a Faraday cage, the world
around us is constantly awash with RF signals
from everything from Wi-Fi to FM radio stations
to satellite transmissions, so the K18 set to its
highest sensitivity will always show RF activity ...
