Same MDC1200 Question, Again...

[Gezelle007]

I have an MTS2000 and an MT2000. Both their MDC1200 ID's sound short like the "mdc1200 short" demo in the zip file, so how would I make it sound longer, like the "mdc1200 long" demo. I know that it can be done because I have seen/heard other Jedi's make that sound. I'm sure I'm just programming something wrong. Help would be greatly appreciated...

But does it work properly and if so, why do you want to change the sound it makes?

You can always lengthen the preamble to something longer but doing so just to change the sound it makes seems like a waste of time.

Oh, to be honest, just because it doesn't sound normal. Id never heard the sound it makes until I programmed my radios. Its perfectly functional, and other radios still decode it correctly, but it just seems unorthodox. Haha.

Also, when other radios do decode it with DOS, they mute the entire audio out, so there is no little 2 beep sounds like most radios make.

I hate to tell you, but the two sounds in your file are exactly the same. They sound different because of recording differences, but the MDC chirps are identical. The only thing slightly different on the "MDC1200 Long", is the length of the beep you get on the mic from keying the radio up. It sounds like it is lasting longer than the MDC chirp itself, and you are actually hearing the beep transmitted through the radio. It sounds to me like one is being sent by a mobile and one by a portable, just by the pitch of the MDC chirp.

If you want to change the MDC length, change the "Preamble Bit Sync" option on the MDC settings. I use a preamble of 5, and that's about as long as I can stand it.

Lol, yeah I was hoping that the portables would sound like the mobiles - Hoping to make it sound like the ones in this vid: YouTube - Amtrak P053 at Selma with lots of MDC1200 But I realize now that it is a mobile thing. And I hate having it set to burst before talking.
