Here is something to think about also that may help. Look at the attached file. Rather than using a CTCSS decoder, I used the COR from the control radio.

Subject: Re: [repeater-builder] How to prevent repeating DTMF remote control commands on the TKR-750?
I have set up DTMF remote control for the TKR-750. The control commands
are going to be repeated (and heard, copied by all users) when they
are sent
to the input frequency to remote control the repeater. Is there a
way to
prevent this to ensure remote controls are only accessible to the
admin?
Unless I'm mis-remembering, you should be able to uncheck the box
that says "Remote Access with QT/DQT" in the Remote Control screen. That will allow you to send DTMF to control the repeater without having to send the PL/DPL that the repeater receiver is configured for. After disabling that, you should be able to transmit with no PL tone (or any other "wrong" tone) to command the repeater, but your audio won't be repeated because you're not sending the correct tone to open up the receiver and repeat audio path. Someone listening on the input might still be able to copy your DTMF digits, but at least it won't be repeated out the repeater transmitter.
