It tends to be worse on a slower processor like the BBB or RPi2. We are currently working on a fix which will benefit all Allstar users. However for right now there is no cure. Setting rxaudiodelay to eliminate squelch tail in simpleusb.conf would make it worse as it would add to the delay. It is variable meaning at times it is almost lockstep and at other times several hundred miliseconds or more delay. Also depending on the receiving radios recovery time it may be better or worse. Using PL usually helps it as it slows down RX recovery time. Hang in there we will have a fix in the future. This is not a problem on a simplex node.<br id=FontBreak></span><br><span style='font-family:"Tahoma","sans-serif"'>For those that have not experience this what you hear is a last syllable of your transmission when you release the mike.
