Talker Alias note

[DL4LEX]

Daniel and I discussed it in one of my PR's without finding a good solution for this.
Perhaps we should display the ID, from contacts or dmrid database, as normal in one line and scroll the TA in the bottom line without any break.

[G4EML]

There is a simple solution to the problem in the original post. That problem only occurs if there is no space in the TA Data.

If there is no space then we cannot assume anything about the contents of the TA. In which case we might as well display 16 chars on the first line and the remaining chars on the second line.

Doing this means a long callsign without a trailing space is displayed correctly.

There will be other conditions where the formatting of the TA data is not perfect but it is almost impossible to work in all cases.

I have raised a PR with this change.

It is right if you use the Brandmeister TA displays the Call and the name , I tryed in simplex

OK.

I don't think Daniel, Alex or I have a radio which will send TA (unless we write a TA Tx facility into the OpenGD77).

That would be great if the GD-77 could be made to TX TA data. I wish all DMR radios could do this as it would obviate the need for contact lists.

I did some experiments with this a while ago and it was not difficult to implement.

I can work with Daniel to add this function, and probably use the Line 1 and Line 2 texts from the Boot screen.

I can't remember how many characters TA can transmit, but I'm pretty sure its less than the 2 x 16 characters of Line 1 and Line 2, and to make the best use of the limited number of characters people would need to split the total text across the 2 lines for themselves

e.g.
"VK3KYY Roger"
"Melbourne. AU"

Or something similar.

Also, this would need to be disabled by default, because I've heard it causes big problems on older Motorola repeaters.

The TA on my 878 accepts 26 characters, the GD77 displays only 22 (unless you can scroll the screen). Another small note: if I change the transmitted text of the TA or I turn off the TA transmission, the GD77 continues to view the stored text, until I turn off the GD77 and repower on again

No, the latest firmware supports far more than 22 characters (27 max + Maidenhead locator), but it depends of the TA encoding, it's lesser in UTF-8 or UTF-16.

If you have time, I can capture your TA, just tell me which TG you're connected to.

Cheers.

I used ISO 8bit, but I can also use ISO 7bit or Unicode, unfortunately now I am at work, in the evening if you want, the TG is 22480, but do you think Brandmeister passes the TA transmitted by the radio?

Okay, I'll add this TG to my static configuration, and try to look at your TA.
According to this, it seems so, unless I'm wrong

Cheers.

Daniel

I have started to write the TA Tx functionality, and it is starting to work, it I will need to look again at the Rx TA data, because I currently have some problems with the offsets.

Its getting too late for me to bug fix it tonight, but I'm sure I will be able to fix it quite easily tomorrow morning.


BTW.
People don't realise this, but the radio already transmits TA data when its in Hotspot mode
