Mike,

For those sites that have a FAA 4-letter code, their METARs can be made
available.
There are two ways this is done.

1) The 4-character FAA code is officially changed to a 3-character FAA
code, and then
    an then a "K" is put in front, and the METARs then can go out over data
lines, as
    you noted below.

2) An unofficial 3-character code is assigned, but the site still retains
its 4-character
    FAA code.  An example of this is the AWOS at Houston John S Dunn
Heliport.  The
    official FAA code is 38TE, but a 3-letter code was assigned (MCJ) so
the METARs
    go out as KMCJ.  Another example is Pampa/Mesa Vista TX.  TX13 is the
official FAA
    code, but to get METARs out, a three-letter code of BPC was assigned.

Recently, an AWOS was commissioned at a heliport at the Methodist Hospital
of Indiana
in Indianapolis.  Its FAA code is 81II.  However, the unofficial code of
22L was assigned
to it, presumably b/c they want the AWOS METARs added to NADIN eventually.
See
attachment.

On another subject, only METARs for AWOS-3 or higher are allowed on NADIN
as far as
I know.  AWOS-A, AWOS-AV, AWOS-1, and AWOS-2 are not.
