AirSpy & FM

[millam]

1. Does the AirSpy have any builtin FM traps?
2. When I take out my FM trap I have FM all over the place, just like a rtl dongle. I don't have a specific freq.
Is this normal? I am using an amp.
3. I short the ant input and I still have FM, attenuated alot but still getting thru.
Is this normal?

There has been mention of RF getting into the unit due to poor grounding and lack of proper grounding to the case. There is a video show the how's, why's and mods. Will have to find it, maybe someone has the link handy.
