If you find the info for Channel Element HQ let us all know.  Their website disappeared and the last known phone number is disconnected.  I think they closed their doors a while ago.

  Next question: I have several VHF and UHF 60+ Channel Micors, but have conflicting information on whether or not they can be converted to MARS bands for use to get statewide repeaters here in Oregon. Also does anyone have the contact information on Channel Element HQ in Ohio? They are cheaper and faster than the 'normal' places for re-rocking your elements, as they exchange them straight across.  (Past experience)

    David,

    Thanks for the quick response!  I went back to my manual collection, and
    found that I did have the "C" revision- but the page in question was in the
    wrong place.  Once again, I am glad that I kept these old manuals- there's
    always some tidbit of information that is buried in them that makes it all
    worthwhile.

    Eric,

    The TLN4928A2 was used in UHF Micors only and the schematic can be found in
    manual 6881015E70-C on page 7-14.  If you do not have this, let me know and
    I can scan the pertinent pages and e-mail to you.

    David

    I have two Micor T34RTA3800AA UHF mobile radios that each have a TLN4928A2
    PL encoder installed.  Although I have nearly a dozen Micor manuals, none of
    them include this encoder board.  Every copy of the 6881015E70 manual in my
    library shows the TLN4293A/B, TLN5731A, or the TLN5732A PL encoder- but not
    the TLN4928A2.  The circuit boards are definitely not the same, although the
    circuitry seems to be similar.  Can anyone identify the manual that includes
    a schematic diagram of the TLN4928A2 PL encoder?  Thanks!
