Awesome. Thanks for your response. Is coordination an issue? There's only one other repeater nearby, so I'm thinking that I could just pick another channel. Here are my plans, any critique is welcome: Buy an old Kenwood TKR repeater from ebay and a Chinese made duplexer, both tuned for the channel pair I intend to use. Mod the repeater to work on 12V so that I can connect it to my shack power supply and/or backup batteries. Hoist a commercial UHF antenna cut to 46x.xxx test, test, test... enjoy
