I have a handheld HT1250 UHF radio monitoring a business band repeater, signal is good, repeater PL tone 110.0 .It acts as if it is using carrier squelch as the speaker chirps when the carrier drops out, you know, like its a scanner rather than a proffessional radio that supposed to QUIET-OUT. I am using Moto V4.0 to program it. All the other channels and tones in the radio work well. Could it be this paticular system OR my software settings are wrong?
