It's not very sensible to have both.  You should get things working
properly without multi/broad-cast before you add this complication.

I'm not an expert on auth, but you should not have it, initially,
when debugging without broadcast.   I think it may be needed for
broadcast modes.  I cannot see any indication of the key files
that it must need.

The stratum 1 here will be ineffective.

Setting a local clock to stratum one is not something you want to
do lightly.  I can see no valid reason for doing it here.  I am pretty
sure that having this local clock will make the configuration unstable
when the radio clocks fail.  The only time to have one at stratum one
is if the local clock is being disciplined by something other than ntpd,
and even then there is the problem that ntpd will not know if that
source has failed.

ttl 6 is too large if all the clients are on the same sub-net.  Simple
broadcast would be enough.

Nothing posted to comp.protocols.time.ntp is PRIVATE, and therefore
nothing posted to the feeder email gateway is PRIVATE.  However,
the gateway is broken, so, if possible, please use the newsgroup

I am assuming that the legal notice is bogus, at least as to confidentiality
and I can ignore it and copy into my reply.
