28 MAR, 2005 - 1640 CST Hello Tom... I have no knowledge about the last ARRL Dayton National Convention. However, at the last ARRL National Convention in Arlington, Texas, I believe all attending ARRL officials were credentialed as exhibitors and were not charged a registration or admission fee. I know I did not have to buy or display a ticket. Coy Day or Jim Haynie should be able to verify this. - Dick, W9GIG
