That's the wrong side of the process.

What he is looking to do is eliminate squelch crash heard by the 
receiving radio when the node unkeys.

The SA-818 is capable of sending the burst that many Chinese radios 
decode, which is set by the

Close Tail Tone command, but the sa-818-prog scripts don't have that option, nor the ability to input DCS rather than PL if desired, which the SA-818 also supports.
