[NLRS] More 222 & Up contest .....

[Jon Platt]

How many people used digital modes during last years 222 & Up contest?  I assume it was FT8 (for terrestrial)?   
After reading the QEX article on FT4/FT8, although FT4 surrenders ~ 3 dB to FT8 in terms of sensitivity I wonder if its greater frequency spread between tones would provide higher reliability in decoding, especially the higher in bands you go where frequency spread increases.  Anyone have any experience with this to share?
