TDMA/AMPS Digital Bag Phones Questions - Help please

    I posted this over at alt.cellular.motorola but I see a lot of action
    here at the verizon sibling, so I'm posting here, too. Haven't had a
    response over at motorola and I really need some answers. Thanks.


    I just bought some car phone, techincially not bag, stuff on eBay in
    hopes that one of the components was the holy grail, a TDMA/AMPS unit.
    You can see the auction for a few months at:
    http://cgi.ebay.com/ws/eBayISAPI.dl...5933&item=3080276843&ssPageName=STRK:MEBWN:IT

    (An aside, I sniped this with seven seconds to go and would have won
    this at half the price, but some guy came in at the exact last second
    about a dollar until my snipe bid! Damn!)

    It is my understanding that the large transceiver boxes are the
    digital units. This auction also has an analog box, presumably, in
    it. However, instead of the usual plain aluminum, it has a very fancy
    black wrinkle finish with ribs on one side. The seller apparently was
    a tad confused on this hardware, as it came with both the small
    classic and the large alleged digital boxes, two wiring harnesses, one
    handset harness, and only one handset.

    The handset is SCN 2524A and has printing that says "Digital Network"
    and "Cellular One by Motorola". Cellular One is a roaming partner
    with AT&T in southern Colorado, and when I fire up this puppy and dial
    611, it does connect to AT&T as Roam. (I'm NOT in southern Colorado,
    I'm in the Denver area.)

    But BUMMER! The handset says "Loaner." I tried my SCN2500 handset
    and although it doesn't say "Loaner", it doesn't show signal strength
    like it does when its on its home transceiver.

    So, my questions are:

    1. Does the large 2" thick with central antenna mount mean
    digital/TDMA? Always? Sometimes? Never? This unit is Model Number
    S1977A, Serial 781DPY1950Y

    2. There's a sticker by the antenna with a bar code and AA514662 on
    it. Is this the ESN?

    3. What's up with the fancy case on the 1" thick presumed analog
    unit? What were these made for?

    Any and all factual knowledge greatly appreciated. Larry, are you out
    there?

    I suspect you have a 3 watt amps phone. Do you have a model number from
    that portion of the unit that goes in the trunk?

    This is just a really old analoig cell phone---I had one
    similiar--but was replaced with the smaller transceive models---I am
    no expert, but these were pre tmda days--this uit probably from the
    late 80's mayber early 90's. I personally see no good use for it--as
    the newer units were a lot easier to deal with--the *loaner* just
    means that the handset and tranmitter are not a matched set, but will
    usually work.

    Until the experts show up...

    I have a 1992 analog tranceiver with the black finish/fins and an EE3
    1998 model, with the silver. Don't know anything about the 2" thick
    version.

    Obviously it doesn't have the original handset. Maybe looking up the
    MSN number and finding the year of manufacture will provide more
    clues. What year did TDMA/analog come out?

    As far as the holy grail, Im a little confused, it's been awhile.. was
    it a 3 watt TDMA booster as well, or the ability to use as a scanner
    or just getting a 3 watt analog phone that could get activated on a
    digital account?

    As far as getting it activated maybe a prepaid.

    If you can make a call, wonder what's the way to determine if it's in
    digital or analog. Must be some phone setting or display, right?

    "HANDSETS: Most Motorola handsets are interchangeable, when a handset
    is used with a transceiver other than the one it was designed for the
    display will show "LOANER". Some features and buttons may not
    work,..."

    Thanks for your thoughts, guys, but I"m only getting more confused.
    Responses, briefly:

    1) The Model number was in my first post: S1977A, and S/N of
    781DPY1950Y. Doesn't the date of mfg appear int he S/N coded?
    2) I can't get the correct MSN without the correct handset (the easy
    way) or hardware and techniques I'm not familiar with and don't have.
    3) Probably the thinner box with the nice finish was an AMPS designed
    to be seen in the trunk, unlike the baggers that hide in the sleeve,
    no?
    4) The alleged history of this unit is that it was pulled from a car
    by a guy who was once a phone dealer way back when. Obviously, he is
    either befuddled or misleading, due to the two types of units.
    5) My hopes that the large unit is digital also comes from the
    experiences and helpful information I've been getting from N9WOS. You
    can see his digital car phone box and handset at
    http://n9wos.home.att.net/cell/specs/19901xtmsb.html . Mine is just
    like it.
    6) No, it was never an amplifier system, actual 3W TDMA.

    Thanks to all, pzo

    My understanding is that the first character of the alphabetic part of the
    SN, determines if it is A(Analog) or D (Digital). I'd say that since it
    starts with a D, it is most likely digital.

    Ah, if it were only so simple! No, the first letter id's the place of
    manufacture. The Motorola Bible offers only the letter "G", which
    means it was made in Libertyville (Ohio?). As to "D", only the dead
    Motorola gods now know, apparently.

    Since my first post, I have also looked up (via the Bible) the date of
    mfg, and it's not encouraging. December, 1989. But N9WOS has pointed
    out to me that that is the timeframe that D-AMPS, precursor to TDMA,
    was arriving. So it MIGHT be digital, but w/o the right handset I'm
    having trouble arriving at a functional phone.

    The black 1" box, BTW, was made in 1995. I hooked it up last night,
    and it roams to Verizon. The handset that came in the purchase behaves
    just like when it's on the large box, "Loaner". My other HS from
    another bagger displays correctly with signal strength. Some of the
    functions work, like displaying the phone number of the box. Others,
    like last ten numbers dialed, don't.

    Onward we go.
