The (default) limit of three simultaneous connections to different
nodes was arrived at many years ago through experiment and debate.
In those days, there was still some justification for multiple
connections as the internet was slower and (in places) a bit
unreliable. Those days are long gone and that is no longer the
case. As far as I am concerned all multiple connections achieve is
an increase the duplicate traffic flowing from nodes (which client
programs don't always deduplicate properly). No one has
demonstrated any advantage to having more than one connection in
terms of speed of arrival of spots - which I presume is the point
of having more. Two connections provide resilience in connection
to the wider cluster (useful in contests) but not much else. <br>
<br>
The kicker is that all major nodes already have have many
interconnections to other nodes. They manage this diversity so
that a client user - does - not - need - to - roll their own
"solution". If a user thinks that they can get a better result by
doing something themselves then I would a) like them to try one
the major nodes in the UK, Spain, Germany and other European
countries first and then b) if they can <u>demonstrate</u> an
advantage of more than a second connecting to another node, then
communicate with your local node and ask *them* to connect to that
node rather than doing it yourself. This will then help everyone.<br>

Dirk,

</div>
<div>No, nothing wrong with it, it works perfectly but
if you read back through some messages to this
reflector, there have been complaints about HamClock
sending a show/heading after every spot so it can use
the response to plot the spotted callsign on a map.
This change stops that and the calculation is done
locally on the HamClock.</div>
<div><br>
</div>
<div>Now HamClock will be very quiet, will only issue a
handful of commands on connect and that’s about it.</div>

As previously mentioned, I’ve been in
regular contact with the author of HamClock
and following feedback, I am beta testing a
version of HamClock which no longer uses the
show/heading command for locating stations
and plotting them on the map. It now does
all the calculations locally.

<div>Once this has gone through testing
and rolls out, it will rely on the
HamClock owners to update their
software. Elwood feels that the
half-life for HamClock updates is a
couple of months so it will take a
while for the changes to pickle
through but we should start seeing a
decrease in show/heading commands
straight away and that decrease will
continue as more people update.</div>
<div><br>
</div>
<div>Hopefully this will satisfy
everyone.</div>
