I scan the 160.000 to 174.000 because thats what the forest service uses. all my frequencies come in nice and loud except this frequency range, This range the frequencies are so low but clear. I use a pro 197 scanner. I use the NFM mode with the ATT mode on and the audio booster on for these frequencies. any suggestions on how to boost these channels so you can hear them. I stream this feed through radio reference. Thanks for any help
