PCKEUPER

Hello I am new to the mygmrs network, and learning. Thank you for putting this network together. A Couple Questions: - How are the repeaters linked to create a network across the nation. - Does the Tucson Area 650 repeater link to the National net all the time, ie what you broadcast here in Tucson through the 650 repeater goes Nationally 24/7? - In viewing the repeater list, for the Las Angeles, area, I don't see one that covers Monrovia CA. Am I missing something in my search? Thank you wrjf355
