Hash like noise on NV Highway Patrol TG

[N7WDZ]

Using a Uniden SDS200, while monitoring the **Nevada Shared Radio System / NV Highway Patrol / Las Vegas 2 (I-15) TGID 05-122 ** I hear a "Digital Hash type noise. Sometimes its a few seconds and sometimes it seems like it never ends. Other times there is actual audio.
I can avoid the TG but then I may miss some interesting audio.
Any idea what that noise is or how I can prevent it, if possible?

Thanks!

Update- Possibly I have the issue remedied. Noticed the hash noise was always happening when the scanner stop on 1 specific (repeater) site.
Once I programmed the System to avoid that site, the issue seemed to no occur any more.

Sounds like you were hearing MDT traffic.
