An idea how to use WinTest:

- SAC contest in MIXED mode! (although there is no MIXED mode in SAC)

- Start 4 sessions of WinTest at your computer with different log names before the contest and after every hour switch to next window, set the serial number correct by EDIT->EDIT SERIAL NUMBER... and start logging in new window. This way the dupe calculation is correct. SAC does not let you work the same station again on the same band in different mode and calls it dupe correctly.

- You have to manually account the multipliers but it is OK to do so on paper as the maximum is only 40.

After the contest you just have to make 4 cabrillo files and lift them together. No modifications needed other than claimed score should you wish to correct it and it is easy to calculate if you know your SSB and CW QSOs and mults.
