Calcord is sometimes used by Vallejo fire when a medical transport helicopter touches down.
Clemars 1-5 are pretty quiet. Occasionally I hear stuff on Clemars 3/Nalemars, but I can't make it out. Perhaps if you had a better antenna than I do it would be readable. I haven't checked Clemars 6-10.
I think OES White Fire 2 or 3 is in use, occasionally, on large incidents, but I can't swear to it.
