All day long QRM on high HF bands EA3HSO on 29/9/14
Hello,

After a few months in my new QTH, I started getting really strong interference on the higher HF bands. They happen every 50 Kz more or less and are permanent.

I've started a small fox hunt to see if there's a visible suspect in a nearby building (HVAC, etc.), but haven't pinpointed the origin yet.

If anyone recognizes this noise pattern any advice would be greatly appreciated.

Here are links to the band scope captures:

All the best,
