I set up the network at N2NT CQWW SSB M/2 and operated at N2NU CQWW CW M/2.
I agree with K3NA that writelog should have the ability to have a fast
restart.
As a side note, I didn't setup the network and log file at N2NU and the "m"
column and the band change counter didn't work right all weekend. I think
that they didn't use the same .wl file to setup the three computers and it
didn't sync up. One of the computers stutered and the frequency would
change for a second here and there and some of the log entries would be
recorded with the wrong frequency. Other than that didn't have any
problems.

Subject: [WriteLog] WL in a M/M Station
Dear WLers,
I'm doing some investigation of various loggers that support a M/M
configuration. I've only used WL in a limited way so far, single op in SS,
and I'm very impressed. But I've thoroughly perused the excellent
documentation available as it pertains to M/M operations and it raises a few
questions.
1. The existence of a WL server. I presume this is a requirement when
running M/M?
Any of the operating positions can act as the server or it can be a machine
on the network without a rig.
2. Recovery after restart. I am intrigued and pleased by the WL design
that appears to (re)populate the local log when a position is (re)started.
I believe the implication of this is that every position sees all QSOs/Mults
even if one or more positions had to be restarted during the contest. True?
Yes
3. Recovery of the WL server. Can someone please fill me in on how/if the
server can be restarted and recovered? I did not see any details on this.
For example, if the server dies and needs to be restarted (let's say a
simple Windoze hang, no hardware breakage)... Meanwhile the positions
continue to be able to operate? When the WL server is back up, does it
resynch with the local positions like they can resynch with it after they
die? I'd appreciate a complete, clear explanation of this scenario. If
I've missed it in the doc, just stick my nose in it ;-)
You must restart the computer and register to accept network connections
then each of the operating positions must connect to it.
4. When a local WL dies and gets restarted, does it come up with the band
map it had when it died, a clean band map, or a band map that has been
updated with the events that occurred on the other positions during its
restart?
don't know
5. At any given local position can local rate and aggregate rate be
displayed? Or is it just one or the other?
You can see Rate for all or rate for the current band
6. Can anyone relate operating a M/M or M/2 using WL to doing the same
thing with another logger such as TRLog or CT?
Have only used Writelog in M/2 never used TRLog, only used CT Single Op
7. Is the Ethernet any more/less susceptible to RFI than alternative such
as a serial port daisy chain?
Haven't had problems with ethernet with two legal limit amps running. Never
used serial port daisy chain
8. I see port choices of only COM1-4. My system has COM5 and COM6
configured. Can WL access these COM ports somehow?
Yes you can access any four com ports between Com1-Com15 you must change the
commslot setting in the INI file. See the help files or K9JY.com for
details.
Thanks and Happy Thanksgiving to all.
