Default CP200 Squelch Fail

for awhile ive been listening to my local police department with my motorola cp200 radios, but recently my moto cp200 radios will no longer mute the squelch after the repeater cuts off. usially the radio would mute the squelch tail. now it no longer does so i have an annoying squelch tail. ive never touched the cps yet. the radios are set to 12.5 Khz spacing also. what is wrong? Ive attached a picture of my cps set up for the channel.

From what I see, every thing is correct. Did you just change to the 12.5?

I would say that you need to connect the radio to a service monitor and check the recieve sencitivy. In the narrow mode, it is possable that the sencitivty is to low.

You need the alignment software and a service montior to do this.

I changed it to NFM to see if it would fix it but it didn't. Also I don't think it's the radio cause all of my radios do this.

It could be possible that a setting on the repeater was changed which is causing this.

Have they changed equipment? I'm dealing with a situation where repeaters are Motorola and mobiles/portables are Kenwood. These two manufacturers have different reverse burst protocols and for the most part cannot decode each others reverse burst to prevent the squelch noise after de-key. After narrow-banding, the noise is multiplied and the dispatchers are beeching to high heaven as usual. Working on a kludge right now to eliminate this.

Is this what you are hearing is a quick noise burst or something longer?

It's a really quick burst. Almost like it has no pl or dpl code. Like a CSQ channel.

try changing the "TPL reverse burst" to either non-standard or disabled.
