FSK441 does however allow longer messages than MSK144 which IMHO has some advantages for VHF and up contesting (ie. Sending 6 Character grids.)

As a general comment I believe the VHF and up contesting community seems to be moving towards new digital modes that to me at least don't seem to be well suited to at least some of our contesting activities.

Maybe we should at changing the contests to fit the modes ?
