What model of Flex Radio?  Any electronics between antenna and radio?  
It might be that some electronic stage is getting overloaded by out of 
band signals. Do you see/hear anything like this when you tune far 
outside the bands?

I don't know Flex Radios at all, so others would have to provide more 
specific advice relating to the radio. I do recall though that older 
and/or lower cost models lack a pre-selector or tuned front end, making 
their input (A/D?) more susceptible to overload.
