You have to select both options: "Multipliers count separate on each band" and "Multipliers count separate in each mode"1) I don' t know how to have the multipliers work on each band. I clicked the "multipliers count on multiple bands", but no dice...
2m and up is not supported, except for the IARU Region 1 VHF contest2) The contest is valid on 2M although I do not play there, and I don't know many that do.
There is no way yet to assign special call signs different points, I have to add this in the future. Currently I haven't this time.3) Last is that there are certain stations that are higher points (i.e. the RAC sponsored stations). I didn't see a way to have specific callsigns be worth *more* than usual.
Nevertheless you should be able to run this contest, scoring is not correct but very close and you can correct it yourself. Scoring is not part of the transmitted log.
