Ryan would you read the main trivia again please. K-A-QK-O KJ5 MCV with tonight. Be in that trivia. What is the primary purpose of a duplexer in a repeater system? Is it alpha? To prevent the repeater from hearing its own transmission and saying whoa who said that. Bravo to allow the transmitter and receiver to share a single antenna while providing sufficient isolation between their frequencies. Charlie to provide a safe place for XSRF to go when the SWR gets angry or Delta to keep the transmitter from bullying the receiver. I'll drop it and read it again. KJ5 MCV returning.
