SDS100/SDS200: EMS dispatch always sounds like there’s a helicopter

[seesharp15]

Title. What gives? I’ve always wondered... I’m guessing there’sa setting I need to change or something to mitigate the problem.

Any ideas why this happens? The transmission sounds distant with a helicopter in the background or something

😁

More details needed. Is this an analog frequency you're listening to? P25 trunked? Something else? Is this the only channel you hear this "helicopter" noise on? Is that noise there only when the dispatcher is talking, or every radio on the channel?
