Strong hum at nigths in Southern Finland
- I had very little hum many months here in Helsinki suburban area,but a
few days ago it began get strong at nights and I can hear it also at
daytime,when it´s varying a lot.In a little cottage in rural area 80
kilometers fom Helsinki I have the hum almost 24/7,there we have long
air wires carrying electricity and they collect very much RF energy
from LW/MW/SW activity and ionospheric reflection ads total RF energy
when it`s dark.I think there is a glue with total RF energy and the hum.
