<DIV>10-4, figured that out long time ago, but all the interest in using DSP in
this and I thought it would work. It might on a different platform. I opened a
Mantis ticket on it a few years ago. But it really is a reason to stick with PL
decode and squelch as done by Motorola and GE, why re-invent the wheel? I have
one remote “private” node using a HT10 and DSP. Works fine for what it is.

<DIV>DSP takes a significant amount of horsepower. Ya don't get something
for nothing; reading a hardware status bit or two is a lot less intensive at the
expense of additional wiring and configuration statements in the config files
than decoding the stream, deriving the signals, etc. any overhead in doing
so is bound to have an effect on other streams going on at that time.</DIV>
<DIV> </DIV>
<DIV>and we humans don't process breaks in audio as we do with visual
perceptions.</DIV>

<DIV>Best I can describe the effect is that the audio is time sliced in 20ms
packets and every other packet is missing, left out. and it does not happen
when audio is especially loud or quiet. Sometimes it happens on the time
announcements, which are absolutely perfect 99% of the time.
