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
