Please note: Please be attentive to the amount of time you use the system during a given day, there by allowing more amateurs to use the system.  Be courteous to your fellow operators while using the system.

Due to the nature and wide coverage of the system, when one repeater is in use for an extended period, this is also tying up many repeaters.   Please consider using simplex or other repeater systems in the area for extended conversations.  Also be aware that what you say on the system can be heard over many thousands of square miles. 

Also, because of the many links, please remember to key you mic at least 1/2 second before speaking if you are using any of the repeaters other than the Hollis machines. How we use it can make or break the effectiveness of the system.
