I went, I talked on my channel, it worked, I went back to work.
They're using a RIOS (?). NIMS is using Command, Ops, Logistics, Fire, EMS, and Law Branches. You check in using your county and disipline, check which frequency (simplex) you're supposed to use, give two radio checks and you're done.
We were second in line (I think). The EMS and Fire side worked very well, I'm not sure about Law. You have to remember to key up for about 2 seconds before transmitting or you'll clip your entire transmission.
But overall we're achieving the interoperability that we didn't have a year ago so much progress has been made.
