[P25nx] Welcome

Bryan,

What prompted the switch from Google Groups?  As far as I could tell there
was no issue with the way it was working.  The way I see it you just took a
struggling project and removed access to the archives of valuable
information and switched to a mail list with a more archaic interface.  I
use Google Groups all the time and have had no issues whatsoever.  Now, if
you were switching from Yahoo Groups I might support the move.  I for one
vote for a switch back to the Google Group.

I am considering bringing the K8BIG repeaters back online as V2 but have
been a bit concerned about the stability issues - so I haven't wasted my
time - which I don't have much of these days.  I just procured a high-tier
server for the repeater site which I am setting up to run VMware ESXi so I
can run mutliple VMs including a D-Star Gateway and possibly 2 P25NX nodes
(One for VHF, one for UHF).  Hopefully this will get around some of the
issues some have had with SD Cards, etc on the PIs.  I am running RAID 50
on the server with 8 drives, 128GB RAM and 2 x 8-Core Xeon E5 processors.
I would certainly hope that that will be enough horsepower.  It was
surprisingly affordable as well.

Regarding the dropped audio packets on the network - we deal with that at
work frequently when customers don't purchase their leased lines/MPLS
Circuits with appropriate LoS agreements.  The P25 data streams can deal
with some latency and packet loss but high-jitter, high latency networks
such as the internet are not ideal.  I suspect most of the issues are due
to this.  If a carrier's network gets busy it just dumps the traffic into a
"Best Effort" pool and sends it when the bandwidth is available - if the
bandwidth doesn't become available within a specified time window the
packets are simply dropped.  Other than adding buffering of some sort I
don't know if there is a good solution to this.  This is an challenge for
every internet-linked digital radio network.

Thanks.
