Hello friends

Post by Nasseralnaqeeb41 »

I have a Vertex evx-R70 repeater, and I have programmed a Motorola DP4800 and DM4600, but the device has a problem when I send from the fixed device. The call appears on the mobile device, but without sound upon initial pressing of the PTT button. The sound was issued after two or more presses on the PTT button, and sometimes when we press the PTT button on the mobile device, it responded and the sound appeared.

Sounds like its the repeater or installation. Are you using FM or DMR SFR/DMO mode? Do you have cavity filters? Is common mode rf getting back via coax? Is the firmware up to date? Is the antenna set at least 5 to 10m from the repeater? Is the repeater new?
