My friend and I each have an STi in our motorcycle tank bags. Both STis were recently purchased. His STi was emitting Ka band alerts while we were outside his beach house garage. His STi was in his open tankbag top cover facing down toward the gas tank and it was Ka ing. My STi was facing ahead in my tankbag as quiet as a church mouse. Riding down some country road he was alerted of a Ka band. My STi was silent. There were about 2 building around the area and no LEOs.
My STi was alerting on other X, Ka before and after these episodes. It seems my STi is working correctly. I'm not sure his is.
Also, will a RD alert near TV satellite dishes? If that is a stupid question, then it was from my friend. :-)
