Motorola's MOTOTRBO Talk Permit Tone (TPT)
Motorola's MOTOTRBO Talk Permit Tone (TPT) consists of 4 tones of 40ms
duration, with no silence in between tones. It makes a warble type
sound. I don't remember the tone frequencies off the top of my head
right now.
Update : MOTOTRBO TPT: The exact MOTOTRBO Talk Permit Tone (TPT) tones I couldn't remember the 4 tone frequencies off the top of my head but since found them here;
The CPS will round them to:
1570Hz 40ms
1050Hz 40ms
1570Hz 40ms
1320Hz 40ms
