I have a question about narrow banding. The new frequency setup is for narrower channels and spacing.
I use AU mode and that is supposed to work for the narrower signals. However, on frequencies using narrow band FM, the audio is weaker than before they switched. P25 frequencies are ok, as are regular FM like NOAA weather.
I think AU decides the bandwidth based on frequency. So do I have to change from AU to FM N setting on
the narrow FM frequencies? I have tried audio boost, which helps a bit, but the audio level is still too low compared to regular FM stations. Also, does any know how AU decides which bandwidth/mode it selects (by frequency,etc).
This all started when Ventura County Fire switched to FM N. The forest service freqs are going narrow also and I think their dispatch audio has started sounding weaker. I monitor both.
