Week 10 of Training: Local Emergency and Evacuation Network VHF/UHF

Another week, another class down. This week we learned about Very High Frequency (VHF) and Ultra High Frequency (UHF) radios. This is the range of frequencies used by cell phones and broadcast radio stations, but for our purposes are used for local communications (e.g. motor pool cars or radios used to communicate if the infrastructure in the host city goes belly up during an emergency). The FSI catalog describes the class as: 

"This course will train the Department's Information Resources Management operational and maintenance personnel in the operation programming, installation, and maintenance of VHF/UHF and Repeater deployed wireless systems overseas."

That's a pretty decent description of the learning aspects of the class. What it doesn't describe is the 'kid-in-a-candy-shop' atmosphere of a bunch of adults (I think...) playing with what, for all intents and purposes, were giant walkie-talkies in the classroom. Part of this was because the instructor was quite entertaining and part was because the course material (at the depth we were going) wasn't incredibly difficult, but either way, we had a good time. Oh yeah, and everyone passed, so we couldn't have been goofing off too much!
