Looking on the VLF spectrum I notice that noise at 4kHz or lower is abt 30dB less than

around 10kHz or higher (see screenshot).

So wouldn't it make sense to trx around 4kHz?

Wouldn't the 30dB noise advantage outweigh the disadvantages like antenna efficiency etc?

Or is this noise situation different at other locations?
