Remember though that while digital modes are specifically not prohibited,
all contacts must be made station to station. The use of repeaters
INCLUDING digipeaters and satellites is prohibited in all ARRL VHF contests
on any mode. Thus working people through PacketClusters which was (but I
think is not now) allowed in the Field Day is NOT allowed in the VHF
contests.
PSK31 and WSJT are two digital modes whose characteristics make them
excellent choices for weak signal work.
I must defer to the digital mavens as to the correct settings although I
think there are few differences between what is used on HF and VHF these
days.
