In SM2 the noise is well above S9 most times, and as far as I can see the
direction is SE from here. I have not been able to establish an on/off
pattern, but it is a total relief when this noise generator is switched off..
The purpose of the thing remains unknown to me, but as SM6CPY says, the
signal peaks around 1865 kHz and the passband is at least ranging from 1800
to 2100 kHz.
Interesting..
