i'm also considering one of those ads-sr1 simplex repeaters, just to do a quick setup for doing range checking around my local area. the question i have is how do i program the darn thing if i do not have dtmf keypad on my radio. i guess the answer is 'go buy one'! it is interesting, living on the side but not top of a hill, how going up one more storey in my house can reach repeaters quite a distance away.
