[Motorola] Turn down Quantar Morse ID dev?

[Coote, Jay]

Does anyone have suggestions for turning down the deviation, as well as adjusting the (annoying) 1000-Hz tone of the Morse ID to 500-600 Hz in Quantar bases and repeaters?   The tone and loud modulation are irritating,

I'm hoping there are software or firmware remedies, rather than my idea of finding the 1000-Hz tone oscillator and butchering the circuit board.

Thanks,

Jay
