APX 4500 scan issues

[Cardiac69]

At our FD, we have 16 remote mount APX 4500's (700mHz P25 PII system) that perform beautifully. Trouble is, I can't get them to scan. We own the APX CPS and they program fine. There is a scan list set up in the programming, and we can even add and drop talkgroups right from the radio. Press scan, and all we can hear is the talkgroup that is visible. I know there is traffic on the other talkgroups, as I have my APX7000 sitting next to me. I am fairly knowledgeable on programming with the Moto CPS, but I have to be missing something.

Ideas?

Have you assigned the scan list to the personality?
(Create personality, then create zone/channel, then create scan list, then go back to personality and select that scan list)

Is the microphone in a grounded microphone hanger?

Yes, I created that within the CPS when programming. I need to check how well it is grounded as W0JJK suggested. That very well may be the issue. Thanks!

Better yet, under Scan Configuration/Scan Wide, check to see if HUB Suspends Scan is enabled.

If it is, disable it.

I'm checking everything later today. Thank you!

Mic was not grounded and the HUB Suspends was enabled. Double whammy. Thanks guys!

Just to clarify, they weren't telling you to ground the microphone. They were asking if the microphone clip it attaches to was a "grounded" clip. The reason for this is that some Motorola products are programmed to scan when the microphone is hung up (and grounded) and stops scanning when it is removed. You do not have to go and ground the mic hangar.

Got it. It used to lay on the console and not in the mic clip.

Motorola microphones made in the last 20 years don't need a ground wire, as the metal button is isolated from the back of the mic head. Placing it into the clip shorts the two together, providing the HUB signal.

The standard "potato" mics most commonly used with the XTL/APX mobiles (mainly the HMN1090) still have the old style hang-up buttons that need a grounded clip. The keypad mics however have the new ones.
