Many radios, especially those from the Chinese manufacturers and distributors, have a feature that is labeled in the programmer as Frequency Mute.
This feature is Sub-Band Mute with options of
- Off (the mute never engages. Signals are heard on the sub-band regardless of the activity on the main band)
- Tx (mute engages if you are transmitting on the main band)
- Rx (mute engages if you are receiving on the main band)
- Tx/Rx (mute engages if you are transmitting or receiving on the main band).
On a dual display radio, the sub band (that which is not marked "Main" will be silenced based on the option engaged.
If you see this option in the programmer, you will know more about what it does to the radio's performance.
