Couple of newb questions:
How do cop's use I/O, is it a manual switch on/off they do per car? Are they seen in a wide range of frequencies or just 34.7? the reason i ask is that I run with both 9500ix and RedLine together - but am not sure how to identify when its an I/O. I would think they use I/O mostly on highways as opposed to city, but could be wrong.
