    Hi All,

    Has anyone figured out how to talk to the Motorola Bag Phone handset ?

    I am specifically interested in the RJ45 interface and how it controls
    the LCD, Keypad, microphone and earphone.

    Any pointers appreciated.

    Sounds like something you would find at 2600. However, AMPS is
    supposed to be shut down very soon, maybe 2008.

    Yup, AMPS is closing down in New Zealand in 8 days, hence the surplus
    of Bag Phone. I am only interested in the handset, not the phone for
    this application.

    I am not 100% certain, but I'm reasonably sure the bag phone handset
    was basically the same technology used in Motorola's SMR phones
    (Specialized Mobile Radio). In the US, that was on 806-865 MHz)

    If I'm right, and of course, you know I am!! (OK, that was a joke...)

    Search around for "Privacy Plus"
    That was Motorola's trade name for their SMR products.
    Someone with an old service manual might be able to help you.

    If you want a list of all the former Motorola service shops, many of
    which have since closed up shop since Cellular/PCS put such a dent in
    two-way radio sales, send me an email and I'll forward you the Excel
    sheet I have.
