Before you
get on the air.
Is the repeater currently available?

Which settings should I save?
Receive on 146.950 MHz and transmit on 146.350 MHz using a negative 0.600 MHz offset and a 103.5 Hz transmit CTCSS tone. These are the published reference settings.
Do sensor readings mean the repeater is working?
No. The environmental feed reports temperature and humidity at Gunung Ledang. It does not monitor the repeater’s radio operation.
