Usage is Rare
I have had a dedicated radio for this freq on my desk for 6 months and have heard three tests and no other traffic. In theory, every fire, police, EMS, EMA, etc. in the valley has at least one of these radios in dispatch. There is only one gaming company that I know of that also has taken advantage of this backup communication. There used to be a weekly test, but since they have moved to this next generation M/A, they have abandoned this test. Basically, this system is used for the most extreme "oh heck" moments, for which we have yet to see to mobilize this backup (as far as I've noted). As always, it never hurts to have it scanning along all of those other never-heard freqs.
