These are signals in the ISM band. The horizontal bar is a nearby (outdoor?) sensor. They are very wideband and pita for shure.?
These signals are very common in urban surroundings..

Thanks for your reply.
The red segment, is a quite loud signal, and from what i have seen is is spread over the 2m and 70cm band. And, we seem to see this signal not only in my house but also surrounding houses in a distance of more than 500 meters. What brings us to to a discussion i have with some other HAM'd. does someone make use of amplifiers whitout knowing what is gooing on on the bands. There are a lot of preppers and also hobbyists that like to see if they can strengten a signal without knowing the effects of it. The Red signal transmittion gives over the whole horizontal image a signal and i hink it is in fact "splatter"? over the a wide frequency area.? It is not harmonics but in this case that high energy it spreads way to far.?
?
What i am searcing for is :
1) Could i use TinyGS to make messurements to see how wide signal is "splattering"?
2) Am i able to make a recording into the TinyGS for lets say 2 hours since it comes in waves but not om a standard rithm.
3) From there is it possible to figure out, what type of device could make a transmittion at this frequency. I think the 2 meter band, where this is signal is verry visible should be such a signal, it is not lora, not an transmitter, it could be a type of packet radio signal, but, It seems to me a digital signal.
4) it could be interesting to figure out what kind of transmittion it is, like is it a lora signal, a wspr signal, a ft8 signal or packet signal, that makes it a smaller list of candidates.?

In my opinion, the signal strengt and the way it acts on the band is uncommon for CE signed devices. It should not be there, and it it better to find the source and solve the issue.?
?
We have a large transmittion tower i the area full with G5 and other ecquipmemt and maybe there is some sort of malfunction.
?
I can;t imagine this is a normal and acceptable signal, it harms the reception of NOAA, Meteor, Conversations, HAB signals and so on...
?
And i want to learn if it is possible to dril down to find the sources ... and maybe it is a misson impossible but, some guidance how to start would be a first step to a possible solution.?
?
As stated i am new, and learning, and want to learn, and if it is a sensor, i want to find it, and see how we can solve the issue?
?
I agree with you it points in the direction of a sensor (but on a frequency that is not common used for sensors as far as i know)? ... but it is one that does not comply to the regulations as fas as i know, and it is causing issues... for me as a ham ..? :-(?
