Hello guys!
For several days, I have been experiencing annoying noise in the 30 meter band.
The peculiarity is that it starts from 17.45 UTC and ends at 22.30 UTC.
Before, I only have a slight increase in noise in all HFs, but not too much.
You also hear at 5060 kHz and 20240 kHz, the multiples of the original frequency.
what do you think it could be?
