The repeater itself is comprised of two Motorola CM300 mobile radios mated to a pair of Raspberry Pi 3b’s. One Pi is dedicated to do the analog repeater operations. It runs as an AllStar Node.
The other Pi is running Pi-Star which accomplishes all the digital modes available on KAMBRK.
KAMBRK achieves the various different modes of service based on use case. Meaning depending on which mode has been triggered – that currently active mode will be dominant for a predefined amount of silent time before reverting to scanning for the next mode to be triggered.
