Hello Dylan,
I have 2 RB17P. The output tone is the T-CDC setting. I just have a few repeaters in the Silicon Valley area so I program them by hand for the RB17P.
Go to the channel with the Plus sign that is the correct frequency. Channel 23-30
Press Green Menu button
Press ^ and go to selection 03
Then press OK
Press the tiny side button on the left to select the Tone type.
Then Press OK to save.
If you want to turn off Dual Watch so you only see one channel, frequency on your screen,
Go to Menu Item 07 D.Standby
Turn if Off
Now you will only see one channel, frequency on your screen.
Best Regards, Doug
