this is a bit like religion, it seems everyone believes something a bit different. The default is of course 2 seconds. However I've seen many a review where the individual suggested changing the channel scan delay to 4 seconds as there would be much less tendency to miss a follow up transmission. Is this true? Have you all found this to be more so the case, or do you still recommend sticking with the default of 2 seconds. I appreciate your input. Just trying to maximize my results and enjoyment.
