MDC PTT tones

[dixie729]

I've programmed 3 Motorola XTS3000 VHF radios with MDC signalling enabled with PTT ID on most of the channels we use.

Radio1: The tone is short when I key up on that channel. On another channel the tone is long when i key up. It is set to (leading and trailing).

Radio2: All the PTT tones are long on all the channels. (leading and trailing).

Radio3: The tone is short on one channel. On another channel the tone is long. (leading)

Conventional standard VHF system.

Why is this happening on some channels and not on others?

The channels must be programmed under separate personalities and each personality has a specific mdc system assigned to it. Under the MDC system menu theres options for Leading PTT-ID, Trailing PTT-ID, PTT-ID Sidetone, and PTT-ID Short Sidetone

PTT-ID Short Sidetone is the single short beep you hear when you press the PTT button

PTT-ID Sidetone is the long beep you hear when you press it

The beeps are to remind you its sending the mdc id signal and for you to wait before talking

Short side tone is not an option in the cps.
Leading PTT-ID - Enabled
PTT ID Sidetone - Enabled
Trailing PTT-ID - Enabled

That's all that's under the MDC System under the General tab
