    Default XPR8300/8400 controller quetions

    After a discussion, we plan on replacing some of our aging MASTR II's. We have been bitten with the TRBO bug. We wouldn't be utilizing IP site connect on our VHF repeaters.

    We would like run the repeaters in dual mode. Is it possible to use a external controller like a s com 7330 in analog mode and use the internal controller in digital mode while the repeater is in Dynamic Dual Mode? Our main repeater has a voting system on it and our two other secondary repeaters are linked together, so we would utilize the s com 7330's for that purpose. We were also thinking about going the vertex route but I know the vertex repeaters are limited to some degree.

    Also are new repeaters shipped with Dynamic Dual Mode or is that a option that has to be added later. We would obviously buy a MOL subscription if we plan on buying 3 new XPR repeaters.

    It appears so, from the System Planner

    4.19 Dynamic Mixed Mode System Design Considerations
    During Dynamic Mixed Mode operation, the repeater dynamically switches between analog and
    digital modes to transmit analog and digital calls. It is only supported in Single Site Conventional
    mode. A Dynamic Mixed Mode channel is a programmable channel in the repeater and the
    channel can be added using the CPS.
    To support DMM feature in the repeater, the following design rules have been laid out.
    1. Once a call type (analog or digital) has been qualified, the repeater will not try to qualify
    another call type until the current call is complete, including the call hang time hang and
    channel hang time. For digital calls, the hang time needs to be expired on both logical
    channels. Analog call type includes an over-the-air call or any operation (PTT, pin knockdown)
    on the 4-wire Analog Repeater Interface (ARI) trying to access the repeater.
    2. Analog console device(s) are supported only when the repeater has not qualified an over-theair
    digital call. An audible alert (channel busy tone) is generated over the speaker and Rx
    audio pins on the 4-wire repeater interface to indicate that the channel is busy and that the
    console access has been denied.
    3. Only PL (DPL/TPL) squelch type repeat is supported in MOTOTRBO repeater as CSQ repeat
    is not supported. However, if the receive squelch type is configured to CSQ, the received
    audio is sent over the Rx audio accessory pin for community repeater operation.
    4. To ensure proper Dynamic Mixed Mode operation, only exclusive CWID transmission is
    supported in MOTOTRBO repeater operating in Dynamic Mixed Mode, while mixed CWID is
    not supported in order to be compliant with the digital mode of operation. Furthermore, the
    exclusive CWID transmission cannot be interrupted by either over-the-air or repeater
    accessory PTT transmission.

    No as far as I know it must be purchased.

    Thanks for the info Magnus

    Digital mode does not support any kind of IP connections including RDAC when operating in Dual Mixed Mode.

    An EID is required to be purchased and installed for each repeater wishing to operate in DMM.

    We wouldn't be using any kind of IP connection on our VHF machines so not having that is no big deal.

    Now is the DMM EID only good for one radio or can you use the EID on multiple radios?

    You must purchase one for each.

    Thanks Mangnus that's what I thought.

    Look at the Vertex EVX-R70 Repeater

    It is completely based on the XPR8400, but has Mixed Mode capability out of the box and no EID is required for programming

    That is the other option we are looking at. Just wasn't sure if they limited the EVX-R70 to some degree. I'll have to take a look at a sample codeplug for the R70.
