[App_rpt-users] Chicken Burst tweak

[Lu Vencl]

Yes, exactly.. Some radios just do not respond to the reverse burst option
and the current length of the chicken burst. 

Below are my current settings in case someone needs to see them.

 

rxchannel=Radio/usb27869

erxgain=-3

etxgain=3

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!

Hi Bryan.

Thanks for the reply.

Yes, I adjusted hangtime and all it does is extend the repeater hang time.

As for the reverse burst method,  it works great with radios that support is
like Motorola portables.

The problem is that the VX5-R does not support reverse burst.  The repeater
is a Motorola repeater, so I pulled the TX PL reed out and got excited about
the chicken burst option on the APP_RPT.. But it still gives me squelch
burst.. Like I said, I just need another 100 MS (200 to be safe) to make
this work..

Is this a parameter that cannot be tweaked?

If not, I can always build an external piece of hardware to add the
additional delay on the PTT. I just thought it might be easier to do this in
software.

Or I can simply wait for a future APP_RPT release that might have this
variable defined to help those with radios that need a little bit more time
in the CTCSS timeout sequence.

Looking for the parameter and file (if not in rpt.conf) where I can tweak
the length of chicken burst. The current amount is not enough for my VX 5R..
I need another 200 MS to be effective.  

Thanks..

Have you gone through and set your timeouts and such in rpt.conf?
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.  Old technique to quiet the receiver before dropping
carrier.

Getting all of these to work correctly is a balancing act between what the
radio can do, and how that coincides with how Asterisk views the world.  

Just some thoughts.
