Is there a way to pre-program a "blank" or other suitable substitute Contact?

There are times I become aware of a TalkGroup that I would like to listen and talk on. Must I use CPEditor to add this TG and write to Radio, or can I use the keypad to add it ad hoc?

I have also sent this question to Radioddity Technical Support and so far they have not understood the question properly, so I still await an answer (24 hours turnaround time for each email reply).

It's quite simple. I am driving with the DB25-D and the others in a conversation want to switch to a TalkGroup that is not already programmed into my codeplug.

How do I use the microphone keypad and radio buttons to program in this new TalkGroup, without a computer being available?

Of course, I pull over to safely change the TalkGroup.

In short; You can't.

However.. it is possible but not as easy as you might think, especially while driving or for quick on-the-fly changes!
Since you cannot ADD NEW channels to the radio, from the radio. You can update existing ones.

So first, you would need a "blank" channel or one that you would want to edit.
Then you would have to add a new contact, entering the TG ID and Name.
Then edit the channel to use that new contact (Talkgroup)
That channel will now use the new talkgroup..

There is a Manual Dial feature.. but I believe that is private call only as I can't see a way of selecting call type.
Plus, manual dialling is all but useless as the contact call timeout only works if you receive a reply within the time set, otherwise it reverts to the default contact
Also there is no easy way to see what contact/talkgroup is active, especially with manual dialled ID's

Ok, I am home late and tired, but appreciate your ideas. I will sleep on these and then study them and get back to you. Thank you.

OK: I added a new "1-Blank" Contact and Rx_Group to my local DMR Repeater with an associated Channel. It looks promising...

Now, I have to study the 3 manuals to figure out how to get "inside" this Channel/Contact so that I can modify using the keys.

I am not sure how Manual Dial would be helpful here, so I will read up about Manual Dial, but you indicated that it will be all but useless in my situation.

Thank you for accommodating my needs.

Your hints lead me to a solution, which is indeed workable:

I have pre-programmed one or more "1-Blank" "2-Blank" etc. contacts at the end of the Contact list, with the next contact number in your Contact List, such as 212, 213, 214, etc. I also make this same Contact a Rx Group.

I then program this into a Channel/Zone for both Contact and Rx Group.

Now on the road, I want to add a new TalkGroup that is not already programmed into my Channel/Zone list.

I select the Channel for 1-Blank

Push P5 - which brings me to Contact Menu

Push Menu/OK/Select button which bring me to Contact List

Push Menu/OK/Select button which brings me to the beginning of my programmed Contact Lists.

Turn the Menu/OK/Select button one or more times counter-clockwise, which brings me to the 1-Blank (etc.) entry at the end of my Contact List

Push Menu/OK/Select button to reveal the Contact menu for this specific Contact; and the choices of SendMsg or Edit

Turn the Menu/OK/Select button until Edit is highlighted

Push Menu/OK/Select button and the Edit Menu reveals: Number, Name, Type and Save. Turn the Menu/OK/Select button to highlight Number and push the Menu/OK/Select button on Number.

Using the B/E key on the top of the radio, delete the programmed number one digit for each push of B/E; and then enter the new TalkGroup number using the keypad on the microphone. Push the Menu/OK/Select button to reveal the Edit menu selections again.

Turn the Menu/OK/Select button until Save is highlighted and Push Menu/OK/Select which should result in a "Contact Saved" screen.

Now use the B/E key to return to the selected 1Blank channel.

Turn the Menu/OK/Select button to go to a different channel and then use it again to return to the 1-Blank channel (this procedure puts the new Contact number into the radio's memory).

You should now be able to transmit and receive on this new Talkgroup!

Of course, you cannot do this while driving, but certainly when in a safety zone or just portable, I will use this method to enter interesting TalkGroups on the fly without connecting a computer.

Thank you for inspiring me to find this solution!

Hi everyone, I have learnt this too late.
Just bought the radio but not intended to be used in a vehicle but as a base.
I set it up with mine Shark RF Hotspot and works well..............BUT.............I need to use the TYT MD2017 handheld to go Contact, manual, group call and that way I use it to change TG's I want to go to or talk to.
I used to have a TYT MD9600 and I could do that from the radio as the code plug was same as TYT MD2017 and Retevis RT 82 (this is also TYT MD2017 re badged as Retevis is only a marketing and sales operation, not an OEM of any kind).

I have the feeling will take some Chinese national to properly translate questions to them and see if the message sinks in their brains ?

Out of this topic, I find the screen too small for mobile.
