Chicken burst will not help. Most of these Chinese radios all use the following logic when CTCSS/DCS is enabled on RX:
- Unmute speaker when signal level is above squelch threshold AND correct tone is detected
- Mute speaker ONLY when signal level falls below squelch threshold
Thus, the loss of CTCSS tone does not mute the radio speaker, and the squelch crash is still heard when the carrier drops.
