You can do nothing about some RFI, such as thunderstorm lightning
My area was hit by a massive thunderstorm and lightning last night.
It is a good opportunity to observe the interference of lightning on KiwiSDR.
I recorded the state of the spectrum accompanied by the lightning burst, images captured within 5 minutes, for your reference.
The results showed that, lightning interferes much more with MW than with high frequency SW at the KiwiSDR.
There is no way to protect against this sort of random interference, the only thing for us to do is to take good lightning protection for the antenna and cables/devices.
