    • As with any linked repeater system, please key, then pause for a breath, before speaking.  It takes time for the system to link and un-link between transmissions.
    • We plan to leave all systems linked under normal conditions.  Sysops can un-link any individual repeater from the system as needed.
    • Plans include adding an additional repeater improving coverage to the south.
