While receiving 800mhz EDAC transmissions on the SDS200 I receive a low rumble/hum through the audio. All other bands and frequencies are fine. Anyone else experience this, and is there a fix, perhaps in the channel audio setting?
Pose that question to your regional scanner group. Check out RR Forums, scroll down to where they are listed by state. Without listening to what you have it’s just a guessing game. When you ask the regional group, list what agency & frequency you are hearing it on.
