Effective for the upcoming CW contest, stations entering in the multi-single category and using a separate station for working multipliers may use separate serial numbers for each band.   This should eliminate any problems with giving out the wrong serial numbers due to timing problems between the run and mult stations which may have occurred during the SSB contest..  

Under CT, configure your network using the MULTI-MULTI setting.  This will allow individual serial numbers on each band.  When you finish, change your summary sheet back to multi single.  Be aware that CT is notorious for serial number problems in some multi-multi setups.

If you are using TRlog select the  QSO NUMBER BY BAND option. 

If you are using WriteLog - under the SETUP menu, select Sort Ordering and Serial Numbers and then select Separate by  Band (or you may select Separate by Radio).  

I have no information available for NA at the moment.

It is very important that your log indicates the correct serial number sent.
