A while back I was surveying a narrowband analog simulcast system for a particular county in California. It was , if I recall,? the 6th generation of simulcast for this county and I would assume they had a good idea on how to make it work over their difficult and widespread terrain. I think they were using ALTO CLE compressor limiter gate processors at the central site. Nothing would be allowed to clip.
