GM,

I recently have some strange, pulsating noise on all 300 deg / NA beverages. Maybe someone have already experienced anything like this - what kind of device it can be? Here is a recording on wide filters in AM, around 3,4MHz (maximum signal).

It's starts late in the evenings and can be heard till 8-9:00 AM. In daylight it gets stronger.

I actually have 2 different RX arrays for NA, the distance is abt 300m from each other, but the noise is abt the same level on both antennas. I guess it means the source can be even few km's away?
