Thanks for all of the tips, etc. The antenna and feedline is new. Tx is a MICOR on 224.000 MHz. The Rx hears very well, better than the 20 of so watts to the antenna. I am convinced that everything else will be ok, but I am putting to more cavities in the system also. So will start conservative at 100 watts to the antenna and see how it goes. Thanks to all.

Mel, Depends mostly on what duplexer you have. Many base type duplexer's will handle 350 W, but at that level of TX power the duplexer might not do enough for the receiver and cause desense. When running only 4 cavities this often happens even with 100 W better commercial rigs. Running higher power does not make the repeater hear better, often hear less, and if you have users running typical 50W rigs why would one need 350 W. Guess the DX and some users could hear better. Users in noisy locations would be helped. 73, ron, n9ee/r >From: Mel Farrer <farrerfolks@ yahoo.com> >Date: 2008/04/13 Sun PM 05:21:34 CDT >To: Repeater-Builder@ yahoogroups. com >Subject: [Repeater-Builder] How much power should you run through a 350 W >duplexer? > >OK, so I need to boost the power of my repeater from the 25-30 watt >level and went to the Telewave website and found the power rating of >the duplexer at 350 W.
