[ldm-users] dvbs vs dvbs2 the sequel



in following gilbert's advice again :), i made the
changes in /etc/sysctl.conf, as well as upgraded
the firmware (which incidentally, michael bradford
from novra said that within a month or so, we will
be able to use cmcs for firmware updates, instead of
having to use the gui!)... the results were much
improved from last week.

statistics since this morning:

missing fragments via Novra S200 -- dvbs1 stream:
ldm@dc1noaa01:~/logs$ grep -c Missing dvbs.log
0

missing fragments via Novra S300 -- dvbs2 stream:
ldm@dc1noaa02:~/logs$ grep -c Missing dvbs.log
2

Gap Errors via Novra S200 -- dvbs1 stream:
ldm@dc1noaa01:~/logs$ grep -c Gap ldmd.log
0

Gap Errors via Novra S300 -- dvbs2 stream:
ldm@dc1noaa02:~/logs$ grep -c Gap ldmd.log
5


for my downstream feeds, i will continue running
both streams for a few more weeks, just in case
something should happen, then probably a week
before the final switch, i will revert to
the s300 dvsb2 stream only.

fyi my current stats after splitting the main
lnb feed to the s300
