The geyser announcement channel is FRS 4-5. I don't recall that we have a written protocol, but the goal is to minimize personal chatter. Usually, personal contacts are initiated by "person's name, please switch to 5 (or 4)". On most radios, the switch to another channel with the same sub-channel is convenient. The Visitor Center does monitor 4-5. Carlton Cross -------------- next part -------------- An HTML attachment was scrubbed... URL: </geyser-list/attachments/20090527/fc97e743/attachment.html>
