I’m just following the rules of the community and this has. Been on my mind for the past few days . I used to be able to listen into law enforcement and even automated the process but they upgraded their system and encrypted their system.

Now I’m theorizing how I can track law enforcement different ways one of which is using a direction finding system. i could super technical and order a bunch of parts and have a desktop running all the time or I can try to dumb it down with analog composition.

I think it’s cool that you can add AC with a ring of iron and winding wires in a specific way (the other way will subtract it)
