Why group members cannot talk to each other on Hytera Repeater, or the repeater cannot communicate with a subscriber radio?
- V
  valerie20Aug 10, 2025
  There are several reasons why group members might not be able to communicate or the repeater might fail to communicate with a subscriber radio: * The TX/RX frequency of the repeater is inconsistent with that of portable/mobile terminals. In this case, re-set the frequencies. * Strong interference signal prevents repeating useful signal. If you cannot remove or bypass the interference source, change to operate at other frequencies. * The group member is out of the coverage of the repeater. To solve this, go within the coverage of the repeater.

  If you are experiencing short communication range or poor audio quality, consider the following: * A damaged connection cable may cause leakage of signal energy. Replace the cable with a new one if necessary. * A loose connection between the antenna connector and the cable, or a complete loss of connection can cause this problem. Secure or replace the cable to resolve this.

What to do if group members cannot talk to each other, even though RX indication is given on Hytera Repeater?
- P

  If group members cannot communicate despite an RX indication, it could be due to: * Your ID being inconsistent with that of other group members. Set your ID to the same as that of other members. * Inconsistent CTCSS/CDCSS settings. Re-set CTCSS/CDCSS.
