I'm the one who found that channel , back early in the year there were some really bad storms , and i was searching and both of my radios 536 and bct15 close called on it, and there was chatter about funnel cloud formation and hail , i do not know if they are taking on new spotters . i know the chief of station six , I'll catch up with him and ask .all i can tell you is they only use this in really severe weather , i programmed that channel in all three of my baofeng radios and was out on my place looking for some good firewood for this winter and caught a couple of key ups , and another voice came on and said your on the storm spotter channel .
If i recall correctly i think i did see that channel listed in the FCC database .
My neighbor used to be with fire dispatch out out of station 1 and i programmed it into his radio , and hiecaught some traffic , about bad weather ..
