CTCSS (Continuous Tone-Coded Squelch System) is a method used in two-way radio communication to filter out unwanted signals from other users on the same channel. To set up CTCSS, follow these steps:

Determine the CTCSS frequency - This is a tone frequency that is unique to your group and will be used to filter out other transmissions that do not use the same CTCSS tone. Choose a frequency from the available list provided by your radio manufacturer.
Set the CTCSS frequency on your radio - Consult your radio's user manual for instructions on how to set the CTCSS frequency. This may involve navigating through menus or using a specific button combination.
Set the same CTCSS frequency on the other radios in your group - It's important that all radios within your group use the same CTCSS frequency to filter out unwanted transmissions.
Test your communication - Once you have set up CTCSS on all radios, test your communication by transmitting and receiving signals. If everything is working correctly, you should only hear transmissions from other radios in your group that are also using the same CTCSS frequency.

Overall, setting up CTCSS is a relatively simple process, but it's important to ensure that all radios within your group are set up correctly to avoid unwanted transmissions.
