In my setup, I am running 7 departments on 1 ttd 6.0. All 7 of those departments get paged out on the same frequency, so, a scanner with only that 1 freq and 1 instance of ttd is all I need for the county wide coverage setup. Ver 5.9b and lower worked perfect for all 7 departments. When I upgraded to ver 6.0, ttd would regonize the tone for the first department on the list but would not pick up the tone for the other 6. I thought this was quite odd. After looking at the tones.cfg file, I noticed the "number" associated with the department was a little off(probably due to me setting up a dept, then removing it from the list) i.e 1, 4, 5, 6, 7, 8, 9. I renumbered the departments in the config file so that it represents the actual order on the list( 1, 2, 3, 4, 5, 6, 7,). After that, ttd 6.0 was picking up the first 2 dept. tones but not the bottom 5. my lengths at the time were A =.4 B=.6. I changed all the B tones to 3 so now my config looks like A=.4 B=3. And now im getting the pages for all 7 departments no issues at all this week. Thought that was a little fluke I wanted to share.
