If you don’t know what a communications unit leader is, or have never had the pleasure of working with one then you need to get on the bandwagon. COMM-Ls are the folks who keep the communication lines open and operational at large incidents. A good chunk of the work is done beforehand by researching what frequencies are common and can be used for interoperability.
Another aspect is knowing who the folks are that would have information on a radio system. They should be able to assemble a group of folks to program radios, do minor repairs and set up temporary radio systems.
If you don’t have a communications unit where you work you should identify someone who will assume light duties and keep things in order. They should be able to work with a COMM-L when they get to you. Keep lists of frequencies in use, where spare parts can be found and know who to go to for Memorandums of Understanding. A good source of people that can help are amateur radio operators who might be employees/members.
Also look for people that have ties to radio shops. No disrespect to them but computer folks rarely know much about RF and that is what you want when nothing is working. Also don’t count on people that wear three hats unless they work/volunteer with you.
Resources are more than just hard objects, they are people who will be there when you need them!
Remember: Have someone update your license for narrowband operation!
