I hear nothing when the Database is Scanning on the SDS100 and 436. This includes all that RR has in its records. All channels are included. Still Deaf. Does anyone actually own one of these radios that is hearing anything. My 396XT I had to deal with all that Control Channel stuff. You don’t need that in the SDS100 and x36 radios.
Are you sure service tags are turned on?
Can you actually hear the control channel in conventional mode?
Do you have NAC's set? Is it set correctly?
Many variables here.
