I was reading the Veil guy's review of radar detectors, as per Radar Roys recomendation. One thing struck me as odd though, he ran at least two radar detectors at once. As I understand even though the detectors did not set each other off, they were probably fighting eachother a fair amount. According to Mike Valentine:
"Our metal case serves as a vault to keep out various electrical interferences from other devices. These interferences are particularly insidious, worse than false alarms, because they can be in there desensitizing your receiving circuits, thereby hurting your warning range, but you have no way of knowing. "
My question is regarding the desensitization, by running two detectors simultaniously, would their be any perminent effects to the detectors from simultanious testing?
