Shane, I would always hook up the COS as well as the CTCSS decode for
one reason. The controller will cut off the audio to the repeater
transmitter as soon as the COS signal goes away. The CTCSS decode will
always hang a few hundred milliseconds and cause a long squelch break on
the repeater output when a user unkeys unless the COS is used to shut
off the audio before the CTCSS decode goes away.
Also - for maintenance using a signal generator without the CTCSS encode
capability, I would like to have the capability to turn off the CTCSS
capability. You might also find in some emergency situation that you
wanted to turn off the CTCSS requirement to allow all users to operate
whether they knew the CTCSS code or not.
Just a thought -
