Hi All:
I thought that we all had homeland responsibilities also, and we are
FCC licensed? You know that we will not be able to work mobile, and
our equipment will have to be crystal controlled? Specifications are
too strict, and limiting the type of antenna will hamper portable emergency
communications? Who will we talk to?
