I'm unsure about the duplexer. Can these be bought from some source? How do I pick an appropriate one for my application? Right now, I am thinking about getting two Alinco 2M mono band radios for this project. I've thought about maybe using the Motorola Maxtrax radios, but am not sure what is required to program them. I know it has to be a radio with the 16 pin connector. Beyond that I'm pretty much green with respect to setting up a repeater. I'd love to setup a small low power local service repater centered on my church's location. I haven't approached the church about this possibility yet, since it's still very early in the planning process. Those Motorola Maxtrax radios are really attractive because it's possible to get a pair of them on eBay for around $100.00 or so. Put these together with a $100.00 computer from our local FreeGeek store, and that's most of a repeater if I understand this all correctly. Ideas, feedback, etc, welcome! :) :) 8-Dale -- Open your mind, Read, Learn, Think, Apply..
