Hi All, I'm pretty inexperienced but find myself in charge of a nice repeater operation, 145.170 - N6FRG in Angels Camp, CA. This is a GE Mastr II mobil unit that has been in service for many, many years. We just replaced the 1980s era SC-1 controller with an Arcom RC210 and have a poping noise when repeating but not during the voice announcements. Any suggestions for a cure will be appreciated.
