MDC & DTMF tones?

[C138NC]

Ok reasoning im bringing this question up is i came across a video on youtube for someone demonstrating a Moto GP300 with full DTMF keypad for HAM "rarely Ive seen those"

Maybe this should be in the ham section but there's not a general discussions area typically that i could think its suitable to be in, sorry if its in the wrong place.

I know MDC is just a TX of the radios unit ID and also a just a databurst before or after but If i had a radio that has full DTMF, would the DTMF transmit some type of tone upon keying up or is this just for kenwood radios? sounds like a telephone dialing in

It wouldnt work if i had a radio thats not a fully DTMF right? though in my GP300 i can actually set up some phone number? just kinda stupid i bring this up but im just kinda testing more things I have never done with it.

I read your post a couple times and am having trouble figuring out what you're saying.

There was a such thing as a DTMF GP300.

You would hold down the PTT button and push DTMF digits to get them to be sent over the air. You could have DTMF and MDC-ID enabled at the same time, but you would have to wait for the pretime tone (if pre-ID was enabled) before you could press digits.

The full keypad model also allows for 2 extra preprogrammed buttons (P1 and P2) which could be set up for monitor, scan delete, whatever... same programmable functions as side buttons. You could also preprogram phone numbers and access codes to auto dial from a preprogrammed list assigned to a button accessed when in phone mode.

I don't know if that answers your questions.
