My 9500ix typically sits there silently until a real threat makes it yell. However, on both runs on the 101 Freeway in Ventura / Santa Barbara County area it goes nuts like you got hit with IO K band at 100' away about every 2 to 3 miles. There is nothing but hills on one side and the ocean on the other at times when this happens. Have not experienced that any place else so don't think it has anything to do with an issue with the RD. Anyone else experience this on the 101 Freeway in the Ventura / Santa Barbara area? Very strange.
