    Default FSB 10685 APX Mobiles, Portables and Consolettes may miss transmit and receive audio on TDMA TalkGroups

    BULLETIN TYPE: Informational Only

    SUBJECT: APX Mobiles, Portables and Consolettes may miss transmit and receive audio on TDMA
    TalkGroups

    MODEL / SYSTEM AFFECTED:
    All APX Mobiles, Portables and Consolettes with R07.xx.xx or R08.xx.xx firmware

    SYMPTOM:
    APX subscriber units when using TDMA TalkGroups may miss transmit or receive audio on calls approximately
    2% of the time when in a strong signal area on multi-site systems or at varying rates of failure when radio is
    operating in the fringe area of a system.
    On single-site systems the problem will only occur in the fringe areas.
    Transmitting radios will not be heard and the system will tear down their calls, but the transmitting user will
    be unaware.
    Receiving radios will unmute late or may unmute to garbled audio.

    CAUSE:
    Software defect

    RESOLUTION:
    Motorola Solutions, Inc. is diligently working on testing the final solution to resolve this problem. Final solution is
    projected to be released in early December 2012. Until that time, the only effective option to mitigate the problem
    is to reconfigure all TalkGroups in the system to be FDMA only. This can be achieved by changing the setting of
    all TalkGroups in the system to FDMA if set to either TDMA or DDM (Dynamic Mixed Mode). Configuration
    changes to the TalkGroups can be accomplished by using the UNC application on the Network Manager (NM)
    Client application. Once the final solution is available, this bulletin will be updated and re-issued as an A revision.

    SEVERITY RECOMMENDATION:
    High - Perform Immediately
    ***Important Note: If TDMA is in use and the radios in question have any of the affected firmware versions, it
    is recommended to address this issue immediately. If TDMA is not in use, there is no immediate need to
    address, but the firmware should be upgraded before TDMA is deployed***

    Sounds like they rushed the latest firmware out the door knowing there was a major bug in it.

    And they wonder why some of us are slow to take up new firmware...

    This has affected APX radios with fw previous to 7. I know of APX radios doing this that have FW 6 in them.

    They don't mention if they're referring to X2 or Phase II but the latter was only introduced in Host R06.00.00 so if it's Phase II then it looks like the bug may have been in there from the original release?

    It's interesting to note that in those same R06 firmware release notes there's a reference to "RX Audio intermittently drops when receiving TDMA Trunked call" for mobile radios?

    It is in reference to Phase II not sure if it affects X2 as well or not.
