Found Elitch Gardens Frequencies!
If anyone is still interested, here are all the active frequencies used by Elitch Gardens staff, I have confirmed all these frequencies and I got the information on what channels they are on their radios and what they are used for all thanks to a friend who works as a security guard there.
I have submitted all these frequencies in to be posted in the database, now it's just up to greenthumb to review them and post them.
451.40000 - This channel is already in the database but not listed as to what channel it is, This is their (Channel 8).
463.32500 - This channel is also in the database but not listed as what channel it is, This is the Security channel (Channel 5), Denver Police also uses this channel when they are in the park.
462.03750 - This is their Channel 3
464.81250 - This is their Channel 10
468.32500 - This is another Security Channel (Channel 1), This channel is not shared with Denver Police.
464.71250 - This is the food services channel (Channel 6), it is used by food crew and food service managers.
468.41250 - This is their Channel 7, which is used only by managers.
463.41250 - Unsure what channel this is but is active
464.21250 - This is their Channel 4, This channel is used mostly by security for relaying important information and details that they do not want everyone throughout the park to hear.
I'm unsure what these channels are used for but they are VERY active channels throughout the day, is seems like they may be water park security, lifeguard and park maintenance channels.
464.01250
467.03750
464.96250
456.40000
464.31260
464.61250
Once again I have confirmed all of these channels and they ARE all active.
If anyone has the 10 Codes and Signals they use please post them up, it would be interesting to know what is going on when they use those.
