The
Micro-RC Repeater Controller is a modern design
GNU open-source repeater controller using all
SMD components. The Micro-RC is centered around
the Atmel ATMega1281 micro controller, picoOS
RTOS and the new CML Microcircuits MX828 CTCSS/DCS/SelCall
full duplex PL encoder/decoder chip. The entire
four layer PCB measures only 3x6" and packs
LOTS of features into a low/mid price range
controller.
Some of the Micro-RC features include:
Atmel ATMega1281 16Mhz firmware flashable and upgradeable.
A real preemptive RTOS executing mutliple tasks.
LCD 2x20 display for real time status display.
Full duplex Tx/Rx PL/DPL supporting up to 15
PL tones.
Onboard
adaptive smart squelch under CPU control.
