[App_rpt-users] Chicken Burst tweak

[John Heron]

Lu,

Note that current commercial kenwoods also have reverse burst except theirs is like 120 degrees but effective... Yeasu and Icom no... Chicken burst best option... Even better is tie pl to incoming signal detect where local or network triggers pl encode and drops when they do... Smart chicken burst!

But it still gives me squelch burst.. Like I said, I just need another 100 MS (200 to be safe) to make this work..

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.  Old technique to quiet the receiver before dropping carrier.
