Kevin, I think we are talk'n about the same thing...prevent intermod in the PA from outside signals which could end up making the PA generate intermod and often amplify it with the possibility of it destroying itself. Even without the generation of intermod an incoming signal might cause the same thing to the PA.
And if this intermod were to be on another stations frequency would interfer with that user. It comes down to which end of the problem you are on. 73, ron, n9ee/r >From: Kevin Custer <[EMAIL PROTECTED]> >Date: 2007/10/23 Tue AM 09:34:08 CDT >To: [email protected] >Subject: Re: [Repeater-Builder] Re: duplexer isolation and receiver noise bud > >Ron Wright wrote: >> The primary reason for a isolator is to prevent intermod > >I strongly disagree... >An isolators main purpose is to prevent a power amplifier from burning >up due to excessive reflected power; due to antenna system issues. > >Kevin Custer > > Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.
