Short Version

Simulcast is a technique in which multiple towers, in different locations, will send out the same signal on identical frequencies at the same time.

(Confusing? We know!)

This is meant to combat reception issues in areas that are widely spread out or highly congested. However, if these signals are not broadcasted at the exact same time with surgical precision, they can, and will cause interference with your scanner. Meaning you can only hear parts of conversations or none at all!

Is this you? Are you in simulcast hell?

Your scanner is working fine but sometimes, on certain channels, the conversation disappears for a few seconds or even minutes until you finally get it again later.

Then, ugh, welcome to the super fantastic world of simulcast distortion!!!

Excited???!!!


No

If you’re here – you’re probably ready to throw your scanner out the window, right?

OK, deep breaths.

Ready?

There is a solution. First, let’s make sure simulcast distortion is actually the issue.

Change each of these settings, one at a time, test, rinse and repeat.

Squelch: Turn all the way up, then all the way down.

Location: Test elsewhere.

Channel Isolation: Only scan the channel you’re having an issue with, turn off all others.

Double Check Frequencies: Make sure 1 channel is 100% in scanner correctly.

Update Scanner Software: It’s free!

This is the low hanging fruit.

Issue still there?

Then you have a simulcast problem and the only solution is a new scanner that can handle simulcast.
