I'm using pure DOS 6.22 (no Windows available on my logging machine), but was 
not using SMARTDRV for TRLog--although I had menus set up in CONFIG.SYS and 
AUTOEXEC.BAT that used SMARTDRV in other situations.

So I copied the SMARTDRV line (loaded high) into the TRLog section of the 
AUTOEXEC.BAT file and tried again.  Now there doesn't seem to be a slowdown, 
neither in the simple ARCI experiment that I described earlier nor in a more 
realistic imaginary event (with the radio interfaced but set to zero output).

End-of-contest shutdown now also goes much more quickly, although that was 
never a problem.  Hopefully there will be no negative side effects of SMARTDRV; 
loading it high prevented a hit on QSO memory.

Thanks for the help.
