I have a question on mobile/portable operation ... I seem to recall that
the FCC dropped the requirement to sign as portable/mobile with the
region the station is operating in. I can't seem to find any reference
to it. I assume that W9XXX/W5 is good operating procedure but is it an
FCC requirement? I do know that a change in the 90s made W5/W9XXX
equally vaid as W9XXX/W5 ....
