I have three APX6500Li Radios hooked up to a NCS-C250 Radio Switch. Two of the three radios transmit fine through the switch. The third radio has a delay when transmitting through the switch. The radio stores the transmission than transmits it out when the PTT button is released. It doesn't appear to be the switch that is the problem. Its strange because when I use the mic directly on the front of the third radio it works fine. This problem only happens when transmitting through the switch to radio three. I can't seem to find any settings in the CPS for APX where I can adjust this.... HELP!
