Thunderstorm Frequency (kHz)
Is there a set frequency in the ADF/NDB band where you could expect to pick up CBs?
I'd imagine that the random nature of each storm would mean there is no set frequency and a bit of hunting would be needed on a flight-by-flight basis, but I've heard that the 200/250 kHz mark is a good starting point.
Any experiences / rules of thumb out there?
Cheers

Thunderstorms generate atmospheric noise which is extremely broadband - like all signals created by arcing (including the old spark gap transmitters).
Tune any HF radio around the dial and you will hear distant thunderstorm activity - throughout the entire shortwave spectrum and beyond - as you probably realise it manifests itself as a loud crackling rush above the normal noise floor.
Atmospheric noise usually peaks at around 10KHz.
So to answer your question - No, there is no specific frequency where you could expect to pick up CB's.

I used to use 250Khz.
You'd definitely hear it crashing away, esp on HF.
Also, I'd use Mark I eyeball too
