As of todays date, it would seem the ARRL Programs and Services Committee has in fact considered the Wuhan Flu issue, and has decided not to make any rule changes.
This is disappointing, current social distancing requirements as well as our new provincial and municipal laws very likely will impact just how, and even whether, we are able to participate in Field Day this year.
It would have been very easy for the ARRL to put rules in place that encourage social distancing early enough for clubs, and individuals, to make alternative arrangements. Part of the Field Day concept has always been adapting your operation to the situation at hand, and this year we have a real doozy of a situation.
I really hope everyone who wishes to participate in Field Day is able to do so this year, and can do so in a safe manner, even if you must operate from home.
