Why does the walkie-talkie in cross-talk condition?

Accurately check the frequency

You can't set up the walkie-talkie only based on the channel number, because the actual frequency corresponding to the same channel number may differ among different brands of walkie-talkies. Therefore, be sure to check the specific frequency value with your teammates, which can be found in the manual of the two way radio in the corresponding frequency comparison table for inquiry.

Setting CTCSS/CDCSS

You need to set both radios to the same CTCSS or DCS, for example, sub-tone 67.0. By doing so, even if the frequency used is the same as that of the other party, other unrelated signals can be filtered out, thus ensuring the accuracy and privacy of communication.

Flexible response to crosstalk

If crosstalk occurs, try changing to a cooler frequency. It is recommended to avoid public frequency bands, because public frequency bands are used by a large number of people and are prone to signal interference and crosstalk, and changing frequency bands can effectively reduce interference and improve communication quality.

Check and Optimize Antenna Settings

Carefully check whether the antenna is firmly installed, and make sure the antenna is tightly screwed to avoid the loose antenna affecting the signal reception and transmission. At the same time, you can try to reduce the power appropriately, for example, from 5 W to 1 W. After reducing the power, the signal coverage will be reduced accordingly, which can reduce the interference from other devices to a certain extent.

Troubleshooting Quality Problems of the Machine

If there are still abnormal communication problems after the above series of operations, it may be due to the quality problems of the intercom itself, such as frequency drift and other faults. At this time, it is recommended to contact the after-sales customer service of the walkie-talkie directly and send the equipment for repair and testing to ensure that the walkie-talkie can be used normally.
