    Hello, ARW!

    Recently i created two powerful allstar platforms for our amateur radio friends and family.

    i would love to get this info out to as many amateur radio operators as soon as I’m able.

    First and most important is The website is self-explanatory, but in a nutshell, ALROTANETS is designed to be a one-stop go-to allstar platform for all groups/clubs and repeater owners to schedule automatic connections to other allstar linkable groups/systems for general chats and nets such as morning/evening drive nets.

    ALROTA 1-6 is used for general everyday connections whereas ALROTA 7-9 is set aside for emergency connections such as earthquakes, hurricanes, tornadoes or any realtime natural/national emergencies, including desktop training.

    The other platform is Of course, we can’t have an East Coast or a SouthCoast reflector without a legit WestCoast Reflector, Right?

    if you folks there at ARW can spread this great info it would be greatly.

    Thank you,
    Ken Varnell
