Is there any way to scan an area for frequencies before flying there?
I had a similar instance, lost GPS and inputs, it tried to fly home and didn't have correct home location (probably related), and then crashed 100m or so away luckily.
Yes there is a way.
A spectrum analyzer, seen a video on you-tube were someone with a quad had issue's and used that to scan the area.
They use to cost a lot but i don't know nowadays. Technology became smaller and cheaper over 2 decades.
It works similar to what a wifi analyzer does on a tablet.
Let us know when you figure something out.
Happy hunting.
