"need to be re-tuned?" Depends on who you are, where the equipment is, what type of duplexers you have and how they are set up.
I can make a strong case for both yea or nay. One of the larger players in the choice to to re-adjust is the Q of the duplexer cavities. Some of the really high-Q large diameter bottles have some fairly sharp F-center band pass and reject points when they're cranked (adjusted) up for high performance applications. If you're running, high power, a high location or a busy site the smart money says probably yes. It's worth checking the duplexer tuning for even very small frequency changes. cheers, skipp > "garyp609" <[EMAIL PROTECTED]> wrote: > If a repeater was on 447.575 and the frequency was changed > to 447.5625 would the duplexers need to be re-tuned? > Thanks & 73's > Gary K2ACY >
