Loopstats weren't enabled so I don't have the frequency data. I'm out
of the office today but

This is an existing system which I don't have the means to change even

As I understand it, the loop time constant determines the poll interval,
but the poll interval doesn't constrain the loop time constant, so
reducing maxpoll will not make the system significantly more re
Danny,
You might recall the message that started the discussion was from a dude
that wanted to selectively listen on one broadcast subnet but not
another. I proposed to add a list of addresses to the broadcastclient
command and include both original broadcast as well as multicast, just

David and others,
The adaptive poll algorithm evolved over many years and many variations.
A summary follows.
1. The poll will not be less than the maximum of the peer poll and
minpoll. The maximum poll will not be greater than maxpoll. This is to
protect the network.
2. The time constant wil
Joseph,
I took a look at the instrument instruction manual to see what is going
on. In typical todayspeak, Symmetricom doesn't say how the gadget works.
I make it what used to be called a Costas direct-conversion receiver.
The test signal is connected to two mixers; the reference oscillator is
