Clark Co. System: New Control Channel?

I was in LV on business last week...loaded the control channels for Clark Co. Syst. as reflected in the database. It worked the first night (Sunday), but by the second night (Monday) the system changed to a new control channel: 860.4375.

The new control channel was still in use last Tuesday. I've since returned home and was ready to submit the new freq. but I'd like for somebody local to confirm my observation first -- I don't want to corrupt the database with the freq. if it was only a fluke -- or if it's old news, etc.

Thanks

860.4375 has been a control channel for the SNACC system for some time. Keep in mind that control channels can change on a given site but the Southern Nevada Radio Scanner Book, 5th Ed. does show it as a control channel on the simulcast system and I think prior editions also showed it as a control channel. Personally, I load all the freqs. for a given site that I want to monitor even if it is a Motorola system just in case the control channel changes.

Thanks for the feedback. I submitted 860.4375 to the RadioReference Database.
