cdm1550 ls uhf not transmitting a pl

Postby FCM » Sat Apr 26, 2014 3:16 pm

I just programmed a cdm1550 ls uhf radio for use with my system. It is not transmitting a pl tone to open my other radios squelch. I double checked that I have tpl and the tone enabled in the cps for both tx and rx fields. It receives incoming signals with pl fine...it is transmitting necause with the monitor pressed on the other radios it sounds fine.any ideas? Thanks

Check the type of squelch activity you are using.
And/Or, and muting type must be compatible.

Need to check with a monitor to confirm whether the tone is present and if so if it is being synthesized properly... assuming your programming is correct

How is the bandwidth for the radio and system programmed, 12.5KHz or 25KHz?

The deviation on the Pro radios tends to run a bit on the low side with the default factory tuning, a radio programmed for narrow will have trouble opening the squelch on some receivers programmed for wide.

All radios are programmed for wide. I returned the radio for an exchange. Ill let you know the outcome. Thanks for all the advice.
