Indeed.  This fixed the problem for me.  Thanks.

And earlier, when I said:

I don't know.  It still seems to do it when run with the -A flag, but only
every second interval -- ie, it starts by receiving a broadcast from the master
server on the net and doesn't send any response; then, after 30 seconds or so,
it sends a packet to and immediately gets a response.  Then 30
seconds later it gets broadcast from that host without having sent anything,

But anyway, in spite of this, it seems to have successfully syncronized with
the broadcasting server now I've given it '-A' so I'm happy!
