Thanks Eric, It will be for experimental purposes mainly with a fairly low duty cycle. I was looking at the UHF 470Mhz band because I can get radios cheap for those freqs. I am not sure about the seperation.... I am not interested in large power outputs, I am looking at 5w max.

What frequency band? What separation between TX and RX? Is the repeater intended for casual, low-duty-cycle purposes such as a family reunion or for high-duty-cycle purposes such as emergency support? The answers to these question will be helpful in guiding you to a solution. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@ yahoogroups. com [mailto:Repeater-Builder@ yahoogroups. com] On Behalf Of gregmrfs Sent: Monday, January 29, 2007 8:04 AM To: Repeater-Builder@ yahoogroups. com Subject: [Repeater-Builder] Hand Held radios as repeaters Hi! I want to build my first repeater using 2 hand held radios mounted in a Pelican case with a gel cell for power. I have no idea where to start or what is required to build the repeater. Can anyone give me some ideas on connecting the radios? So far I think I have to get 2 radios, case, battery. Do I need 2 antennas or should I use a duplexer. I want this setup to be as basic as possible.
