Yeah, that's just too weird that ALL your equipment is malfunctioning and that it happened all at once. I strongly suspect a new source of interference in your area. Try to find a way to check for local interference, buy some crystals and try other frequencies, etc. Radios can't get viruses and all get sick at the same time!! There has got to be a common denominator here, and I think sending your radios in again is going to be a waste of time. If there are no common components whatsoever in the separate systems, it just about has to be outside interference.
