QRM QRM QRM in a would be low noise QTH

28.074MHz  FT8 band  with S5 noise

today ALL BANDS  are polluted with QRM  0 to 1300MHz

S5 Noise 28MHz S7 21 MHZ
whole spectrum is  30dB and higher noise plus carriers  digital smog
 50MHz  30dB noise from the Solar EDGE broadband transmitter

AT  Dutch Telecom say it is within the legal limits
They could not even detect it on their mobile equipment
It is legal to make RF smog as long as the GSM traffic and other services  is just good enough.

23cm 1.3GHz   never ending s7 QRM cracking from direction S-W
28 MHz complete covered with S5 sm noise day and night
50MHz  noise raise to 30dB  in the direction of SOLAR EDGE  system at 50m

from almost 0 to  at least 150 MHz  every 200kHz  a group off digi trash carriers

I have to investigate this myself
The  Agentschap Telecom can only detect radio interference that exceed levels of 50dB
on normal radio HAM receivers 

5362kHz Stanag  signal from Denmark 9+60bd !!

i am not the only HAM negative…
