Below is posts taken from Facebook groups regarding issues since BM turned on Alias with Motorola Radios .........................................................................................................................................

Rick Fiorey

Since the Brandmeister Network has implemented the Hytera “Talker Alias” feature I have been experiencing the following: I see the person’s info coming up on my BlueDV app for my DVMega Bluestack, the DVMega Bluestack is transmitting but there is no info displayed on my radio’s screen other than the signal strength meter. The receiver does not open on the radio and there is no audio coming out of the radio. Basically, I cannot hear the person talking who is running the “Talker Alias”. This happens on my mobile radio (a Motorola XPR 4550 using a DVMega Bluestack on an Android phone). It also happens at home using a DVMega Bluestack either on an Android device or using a Windows 10 computer with BlueDV for windows. The radios at home are all Motorola…, an XPR4550, an XPR7550 and a SL7550e. I also have an Open Spot at home running firmware version 72 which does not support “Talker Alias”. I can hear everyone on that. I am just having problems with the DVMega Bluestack handling “Talker Alias”. Just wondering if others have had this problem?

Yes, I have had similar issues with My Motorola XPR7550 radio and both DVMEGA. 1 RPI with Dualband DVMEGA and 1 with Arduino bluestack connected to RPI. No issues with openspot. Tis all started in the last few days.

What firmware do you run on the radios?

I am running the most current firmwares for all of my Motorola radios.

What according to you is the most current?

Motorola radios do not handle correctly anything other than call information in the embedded signalling fields of DMR superframes. Other in-band data (which were introduced last year in the DMR standard) is placed in embedded signalling fields, which only contained call info before.

This is an issue with Motorola firmwares, I have a DM4600 as my main DMR radio and now I'm planning to replace it with a Hytera MD785 because - as far as I know - there is still no updated firmware which is compatible with this new standard DMR feature, and the issue is very annoying. Also the new BM auto talker alias feature is super cool - now I don't have to manage contact lists as everyone is displayed with their names and callsigns on my Hytera PD785.

openSPOT supports in-band data passthrough since firmware 0084 (beta, but the new stable is coming in a week), but there are settings to turn off in-band data sent to your radio, or from your radio to the network, which give a workaround for these radios.

Yes, the OpenSpot works fine because you have the ability to block this other data from coming in and confusing the Motorola radio. However there is no such option to block talker alias on any DVMega configured device.

Perhaps there could be a switch provided in the BM Self Care section where the user could turn this talker alias feature on or off depending if they have a Hytera radio or not?

That is a good option N1IRL and a very simple fix

Please focus on the following fact: you are talking about receiving groups call and not about transmitting. We cannot apply TA just to some for receivers of group call due multiple radios receive the same stream. In other words: we can only turn this feature off to all.

Please give us more information about the affected radios as not all motorola radios have this problem all the motorola radios (not repeaters) we have tested don't seem to have issues

I'm also having the same issues and I don't think the best solution is to suggest that we sell our Motorola Radios and purchase Hytera Radios. That's pretty foolish, especially when we paid good money for a quality radio.

This feature has been introduced into the Brandmeister Network knowing full well that not all the manufacturers have updated their firmware to support it.

SOLUTION: I respectfully request that a simple ON / OFF Switch be placed into the Brandmeister Self Care Control Panel to be able to disable this Talker Alias feature until such time that all the manufacturers have updated their firmware to support it. If you're having an issue then this solution would permit you to disable the Talker Alias functionality and allow the user to continue to have the best Brandmeister user experience possible.

Brandmeister has always been about giving a DMR user the best possible experience PERIOD. Unfortunately, the addition of this forced Talker Alias seems to be contrary to your initial mission. Hopefully we can get back to the very reliable network we previously enjoyed and be able to hear EVERYONE all the time regardless of Radio Type or method of entry into the network.

Respectfully submitted,

Jim NF3L

P.S.: BM does not transmit TA over repeaters that has issues with transmitting TA: Motorola (has issues with handling), KAIROS (does not support on the transport protocol level yet)

I did NOT suggest anyone to replace their Motorola radios. I wrote that I'm planning to replace mine, because I'm tired of not hearing stations correctly and also because I want the TA feature because it's great.

I get the exact same behaviour with my DVMega BlueDV. I dont have Motorola radios. But the same behaiour as discussed at the start is my what I get. I will try to gather more details.

Dave Livesay Also. I was listening to 4 people talking on my XPR7550 and MMDVM RPI configuration and I could only hear 1 person out of the four. The one person that I could hear had a Hytera radio. The radio would showing activity, I just couldn't hear the audio. Happening very frequently.
