Hello, I am trying to reprogram a bunch of XPR 3500e Motorola radios. I am trying to make an all call channel. I have four channels with different frequencies already in each radio, trying to make a fifth channel as an all call channel that can transmit on the four other channels without having to turn to each channel to transmit. Have seen there is an emergency call option but don’t understand how to do this? Again they all have different frequencies on each channel with a contact for each channel and frequency and a digital Rx as well for each channel. I am using CPS 2.0, simplex frequencies no repeater. Any help and guidance would be greatly appreciated! Thank you!
