<div class="moz-cite-prefix">No doubt it will introduce delays into
the system.<br>
<br>
I am fairly new to using allstar. My first experience was with
the bbb and it did not have the broadcast delay like the Pi2 does.<br>
Granted you hear a delay between input and output of the repeater
using either bbb or PI2.<br>
<br>
Does this mean the Pi2 is actually that much slower? <br>
Maybe the software is not taking advantage of the multi-core
processors yet.<br>
<br>
Don't get wrong, I think this is a great system and we are
changing out hardware controllers for Allstar.<br>
My hat goes off to everyone that has made this type of system
possible.<br>

Yeah, you learn to pause before un-keying.<br>
It is worse sometimes than others.<br>
<br>
I have tried real hard to make it do that on the bbb and it
has not done it.<br>
I was wrong on the radio on the bbb. At one time (pre
lightening strike)I had a Master II with a cat 1000. Right
now it is not my 80's hamtronics exciter with the latest
synthesized receiver on the bbb.<br>
<br>
I wonder if different radios introduce different delays. I
hope to get a chance this week to replace the bbb with a Pi2
and we'll see what difference that makes.<br>
<br>
Thanks for the info.<br>

The problem you are seeing has been a problem in
Allstar for years. 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">
