OK, while the USA drifts from the suggested IARU Region 2 band plan, here is an "almost" compatible digital band plan, "Compatible" with the Region 1 and Region 2 bandplan for digital modes with a couple of exceptions where "wide" and "narrow" digital modes are mixed . I mixed them because the USA has less room for them. Also one of my suggested JT65A frequencies for WSPR and JT65A would differ from current practice in the USA. IF USA hams followed this suggested plan, it would be broadly compatible with Europe's digital plan and would provide a basis for the addition of new modes and illustrate regions for suggested "calling frequencies". Surely too simple? Feedback ? (I can hear Bonnie saying "I told you so" )
