Additionally...are you transmitting PL tones? If you are, and you're not depending on the radio hardware (ie you're doing all the audio processing in Asterisk, and doing direct FM injection), you can try using reversing the phase of the pl before carrier drop to quiet the end user receiver before dropping RF carrier.
