      Can the sample file "flutter.wav" be posted on the ftp site (my audio
      processing ability prefers direct file input -- I don't know how to
      capture the audio as shipped from here). Alternately a time parameter
      of where it occurs in the original Milan wav file would do.

      We have no issue with stamping out excessive Txdelay's!!! What is the
      conversion factor from command parameter numbers to msec.?
      Unfortunately, if this is the case I think it is, communicating with
      the perpetrator is difficult if not impossible. Or are the long TXD's
      and very, low deviation in different packets?

        We wouldn't want to accuse you or Elmer of being jerks. Your collective
        postings speak for you.

        If you are confident that you have looked at the easy stuff, perhaps
        it's time to look at the more difficult stuff. You could breadboard the
        2211 circuit and see if you can duplicate the OT2M performance you are
        seeing or improve upon it. The subject is "not functioning as a digi"
        but I take it you have a problem with decoding signals rather than a
        problem with the digi settings. However, at risk of being told that it's
        "easy stuff" what settings do you have in...

        SMARTBCON (I know... it's supposed to be a digi)
        WAYPOINTS (I know... you probably don't have a GPS connected)

        What do these have to do with decoding? Probably nothing. Heck... you
        could do a DISPlay and post all of your settings.

        > PLEASE - no more well-meaning but un-informed comments from the peanut

        Perhaps I should have just deleted this instead of clicking on send...
        sigh. What an attitude! It's insulting to the other people on this list.
