[WT-support] WPX S/N bug

Wintest has a bug in the serial numbers given during the 
WPX.

When running M1 people are allowed to have two transmitters 
on the same band. When that is done, if both stations are 
working people at the same time period, the SN is not 
reserved or held  until the QSO is logged. This can and does 
result in a bad SN for one or both stations.

The FAQ for WPX states:

Our logging software caused us to give out duplicate serial 
numbers or to give numbers out of sequence. Is this a 
problem?

  No, but only if your log shows the exchange that you 
actually sent. Each QSO line of the Cabrillo log contains 
the sent and received information for that QSO.  As long as 
that line shows what you actually sent to the other station, 
the log checking software will score it correctly.


So if the number was reserved and not used it would not be a 
problem, or if the SAME number was sent it would not be a 
problem. What is a problem is the software changing the 
number after the exchange was sent when the contact is 
logged.

N1MM holds the SN once a call is partially entered. This is 
the correct way to do WPX when two radios happen to be on 
the same band. Since the SN is wrong in M1, it is probably 
wrong in any class where multiple stations can be on the 
same band.
