I'm using a 12.5 KHz narrow band system with 2.5 KHz of deviation so when setting up the URI, I referred to Steve's post "Adjusting Audio Levels" using the URI. I also made the assumption that if a 1 KHZ tone set to 3 KHz of deviation was correct for a 5KHz system then 1.5KHz would be correct for my 2.5KHz system. So I set rxvoice to 1.5KHz and rxtone to .6KHz then with txtone set to 0, I set txvoice to 1.5KHz and txtone to .6KHz. However when this was complete I had low audio through the repeater and only 1.85KHz of dev out. So I went back with the service monitor in duplex mode and adjusted the txvoice up until I got my 2.5KHZ out and the repeater sounds very good as a standalone. I have 2 questions and a comment, first, what are the correct numbers for setting up a 2.5KHz system using the URI's? and why? Second, What would the best way to add a 5KHz node and keep the levels even across the system? Comment: We recorded some voice announcements for repeater ID through our Asterisk phone system at work to produce the wav files and the audio is really great, as a matter of fact I'm very impressed with this whole app_rpt deal !!! Thanks Mark
