National Guard Frequencies
During Hurricanes Katrina and Rita, the National Guard was deployed to the Cajundome to assist us in security. While they were there, they were using XTS5000 portables operating on 400mhz UHF frequencies. The radios were capable of Securenet operation, but they were not using it. There were 2 seperate groups of National Guardsmen there from Louisiana and Ohio (I think) and they both were using the same radios. However, I too listened to them on the State NG TG's in New Orleans, so Im not sure how they decide what system they will use.
