Do somebody now what this is, I read pulses between 8 and 9.2 Ghz with a specctran HF-60102 who max is 9,4 Ghz.

I do have a nabure who radiate me because she want to disturb mine hobby and do not like me so try to get me moved from mine home, I do not like to live in such high frequencies, it is full reading sometimes, I did also think of the smart meters, maybe these transmit to communicate with each other, problem is it interfere with measuring equipment who need ring cores now.

A EL84 can go to 100 Mhz, I have one a long time ago.
