Hello, this might apply to the general scanning discussion as well, but I am trying to effectively monitor the national medevac frequency, 7AG88D, 774.61875, I programmed this in as a monitor on a 12.5 KHz channel in my G4 but recently during a incident it came across with a sound similar to undecoded DMR, like a loud engine running, what would I need to do to effectively monitor this frequency, do I need to input a TG, change the bandwidth? Thank you for any help understanding this issue
