[TowerTalk] Noise appeared on 80m and 40m

[HA3LN]

Hi All,

Yesterday in the LZ-DX contest realized a severe noise on 80m and 40m.
As I work the stn only in contests it's been not articulated this bad so 
far.

Looked up several pages where I checked many RFI sound and video clips 
but not found obvious match. I afraid "my noise" is rather 2x types 
combined. The pulsing one which kinda mutes the band, sounds electric 
fence but the "baseline" might be different.

I have ideas where to start the hunt.

Does anyone recognizes the noise type?

Thanks.

73!
