I prefer active high for just the reason that you described. I usually
fuse my equipment individually, so a blown fuse in the receiver can
cause an active low to be sent to the controller, thereby keying the
transmitter. If I do use active low, I put a pull-up resistor in the
controller and test it see if it keeps the COR high on a receiver power
failure.

Hello to group,
What is the advantage of an active low COR.
Most I have talked to say they have their controllers set that way,
so I set mine that way,plus the Maxtrac I am using as a receiver
default is active low.
I simulated a power failure to the reciever and the line went low and
the transmitter thought it was time to transmit. I also accidently
pulled the cord from the controller off the back of the receiver and
again a low status and the transmitter thought it was time to
transmit. Im not seeing a benefit of a active low COR in those
repects. Should I go to active high or since those things dont usually
happen often leave it LOW..
Any advice or ideas appreciated..
