Dynamic Mixed Mode Configuration

[JMLW33]

I am trying to activate Dynamic Mixed Mode in Mototrbo System. I have Motorola DR3000 repeater, I have more Mototrbo radios DP4800 and more GB300 series and GM series. In fact I tried to configure them by choosing a Dynamic Mixed Mode in the repeater and I configure digital channel and even analog channel on them and when I try to PTT in digital I hear tone as it is busy and on analog I hear voice not clear. Is there anyone can help me in this, please?
In another way, I heared that they use a DM4400 interfaced with the repeater by pins cable. Which way is the true and how step by step, please?
Many thanks

I have an xpr8400 (which looks similar to the DR3000) in mixed mode. I assume you already have only 1 channel setup on the repeater, and its 'dynamic mixed mode'? Make sure the color code matches on the radio and repeater. Is it a busy signal, or is it indicating it did not connect to the repeater?

Many thanks dear brother
I have only one channel setup on the repeater as ''Dynamic Mixed Mode''. For the color code, it's the same on the radios and the repeater.
It isn't a busy signal, but it's a contineous tone as it indicate that there is no connect with the repeater whereas the repeater signalizes the two slots together for the digital and the analog signal disappears.
In analog channel, when press PTT on the radio, there is a connect but the other radio doesn't receive a call but when left PTT I hear noise in the two radios. Where is the problem? and is this feature ''Dynamic Mixed Mode'' must be available in the radios the same as the repeater? or I just have to add two channels (one digtal and one analog). In radios, this feature isn't even available for purchase to activate it whereas I have FW version R02.09.

best regards

make sure you assigned a group id to the contact name under where you entered the transmit information for your digital channel. And its best to test with 2 people so the radios your using to test aren't right next to each other, sometimes the receiving radio will be unable to hear to repeater due to being too close to the transmitting radio

Thank you dear brother
Sure I did a group ID to the contact name and chose it in digital channel contact name.
For the nearness of the transmitter radio and the receiver radio, I don't think it's a problem coz I don't face any problem in digital only mode and in IP site connect but I'll try it.
As I read that in ''Dynamic Mixed Mode'' we can do three channels two digital each one in a slot and one analog. Is this configuration in this mode experienced successfully? And what are specific additional parameters configuration that should be added to make it successful?

I hope to get a help in this.

Well.....technically, yes, but it is not 3 channels like you might be thinking it is. DMM cannot repeat digital and analog at the same time. So when an analog signal comes in, digital will not work. When digital signals come in, analog will not work.

You can have 2 digital signals repeat simultaneously. You can have 1 analog signal repeat. You can't have both. So if you believe that you are going to have 3 channels to use whenever you like, that is incorrect.

Thank you dear brother
In fact I know that DMM can't repeat digital and analog at the same time. What I don't know is that why it doesn't work with me. Is there any additional parameters I have to set up?

Not really. It's pretty easy and straight-forward to set up. Do you have a screenshot of the CPS showing how you have things configured?

Sure, here they are
