Tim, if you want to be a pretentious horse's rear I suggest you select someone else to go head to head with. You need not ever preach to me on good amateur practice. Furthermore it might be best to have some working knowledge of repeaters and related technology that goes into putting them and keeping them on the air before you try to speak as to what causes problems. :roll:arron315, It is not a good idea to KEY or kerchunk a repeater, This ties up the repeater and causes problems and does not comply with "good amateur radio practice". Those repeaters do have serious coverage issues and cannot be brought up from 79Th and Michigan Road with a outdoor anrenna on top of my house that is 40 feet above my roof of my home.This is the 147.165 and the 442.900 repeaters.I have tried to bring them with my call sign and they do not come up.
