MDC 1200 signaling

[FDNY216]

I am attempting to set my Motorola XPR 7550 with MDC 1200 group call

But I can hear all the voice on the frequency and it seems not to mute the voice until they send a signal

How can I get to to silent radio traffic until the tone

If you can give me the steps in order to set it up correctly I would appreciate it

Thank you

In CPS go to the channel you want to be muted until the call is received. Under the RX box with all your frequency info you'll see a thing called signalling squelch, set that to AND.

there is no and in the signaling of the CPS XPR 7550

Yes there is.

Put your CPS in expert view, also.

Just to clarify things, in MDC parlance "group call" refers to an MDC command addressed to a subscriber's -- or more realistically, a group of subscribers' -- "secondary" MDC ID. That secondary ID will be a four digit hex number of which the first (leftmost) digit is E. The function the OP is referring to is, in Motorola speak, a "SelCall."

Works thanks guys

Unmute Rule is usually set to AND/OR so loss of tone or carrier squelches the radio.

I noticed that when the squelch opens after the tones the voice is cut off by 1 sec

What is the setting to overcome it

Do you have DOS enabled for MDC? If so, your coast time may be too long resulting in a cut off reception.
