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 t

Some inverters are quieter than others. I've not encountered any of the Samlex units, but from studying data sheets, it seems that there are two product lines, one of which meets more stringent specs
