Thank you jmoylan69 for responding. I am ashamed to admit that my handheld unit is a cheap Motorola 1.5w walkie talkie. I can select the channel that is pre-programmed RX 462.5500 and TX 467.5500. And I can also set the code to 141.3 Hz. Both units hear the repeater announcement. Then if I use handheld A to transmit, both units hear the response from the response. But it's just a screech and the beep. Both units hear it. But not the actual voice comm. I hope I'm making sense. Since both device can hear the initial announcement and also trigger that...they are accessing the repeater properly. It's the actual communication following the announcement that is without the voice.
