I have been poking around and have yet to find a solution to my problem. I have a training map that we use in Zargabad with a custom base, firing ranges, .... One of the things we have noticed is that comms on ACRE are iffy at best regardless of where we are on the map. This has been tested inside the base, out in the open, two buildings down from each other on the top story with open line of site, and even right next to each other. Even at 5 meters away, on a 148 range set to 5000 the voices come in garbled. Any ideas?
