Interference is something that happens with radio systems, and it will never be a problem that can be checked off as completely solved. It’s more of a game of whack-a-mole – as repeat issues come up, they need to be tracked down to a source. We posted about this recently and had some success preventing the interference that plagued us in the summer and fall.

In the last two weeks, we’ve had several occurrences of what some might call “bleed over” that appears to be All-County Broadcasts (ACBs) originating from Cincinnati or other Hamilton County dispatch centers.

It is only happening in a “perfect storm” scenario, when they’re making an ACB and we have legitimate Butler County radio traffic with a talkgroup assigned to a particular channel. The ACB is hopping on the tail end of the legitimate Butler County transmission.

Here is an example audio file:

In short, BRICS staff and Motorola are working on finding the reason this is happening and a resolution. We just wanted to let you know that we’re aware of it.

If you have an occurrence, contact BRICS with a support ticket or email with the specific date, time and talkgroup affected.
