      Ok, sounds like Close Call is following the band default mappings when in Auto
      mode for demodulation.

      What are the deviation settings in this radio for:

      NFM

      FM

      FMB

      I have not looked to see if these are in the specification section yet.

      Thanks UPMan!

      Since most band defaults in the scanner are NFM, I'd suspect that the service is


      transmitting FM and you have the channel programmed correctly as FM. But, on a
      Close Call hit, FM will overmodulate NFM demodulation and result in the audio
      being much louder.

      I was scanning some conventional public service frequencies with close call in
      DND mode. I noticed when close call came across a local PD frequency, it's audio


      level was much louder than the same one programmed into the radio within a
      group. I have not check the AGC level settings, but wondered if anyone else has
      noticed this as well?
