Updated instructions for setting up N1MM+ for use on Field Day across a BBHN mesh network.

> Never stop and restart networking during a contest! It will corrupt up your logs.

1. It's Field Day.  Expect your network to stop for any one of a dozen reasons.

2. Why use a program that does this?  Having a corrupted electronic log is worse than using paper logs.

A brief - or extended - dropout of the Field Day network does not corrupt the data file. After a generator refueling or a computer crash it is easy to resync and rescore the database at each station. The reference I made about stopping and restarting networking during a contest comes from the developers of N1MM and refers to a user initiated manual stoppage. I don't know how that function can corrupt the database but if the developers warn against it, I'll warn against it too. Charles, K5CS

It seems, at least for the networked logging programs I've seen thus far, the programs rely on the PC's networking or filehandling services which really aren't suited to be fault tolerant.  Maybe it's expecting too much of a "free" program to handle these kinds of network issues.  To go through all the setup and then keep a network and application tech on hand during Field Day to handle the issues doesn't sound like it's making life easier. 

Maybe at some point there will be a logging program that will be as easy to set up as the mesh nodes, without going through machinations of fixed IP's and accommodating latencies.  Now that mesh is becoming a popular Field Day activity maybe these issues can be adequately addressed going forward.  I know one group that used N3FJP software via mesh and "lost" a number of contacts.  N3FJP has addressed some of this with his newer TCP based method but it still doesn't sound like it's quite there yet.
