the field day aspects would be nice for a demo which is what I am hoping to use it for, otherwise it wold just be nice t find stations and their pileups, surfing for w1aw for example :) definitely just one more tool to play with. let me know what I can do to help if anything. and i will try to get that display here as soon as I can
