John,

Christmas island METARs are being sent under the headers such as:
SAKB31 PLCH

The sfmetar_sa.tbl will need the PLCH location added in order to include
these in the decoded output file (just add the PLCH line that you can find in 
the
$GEMTBL/stns/inactive.tbl file).

TAF messages (eg bulletins starting with "FT" are decoded with dctaf).
The $GEMTBL/stns/tafstn.tbl has several of the islands like Palau and Yap
but not Christmas. The sfchck program can be used to show if the decoded
taf station files have any missing station identifies, and nothing there shows 
up
for Christmas.

If you are looking for synoptic reports, then I do find 91490 in the
data stream (It is decoded in the synop files from dclsfc using the 6 digit
identifier 91490):
lsfstns.tbl:PLCH     914900 CHRISTMAS ISLAND/CASSIDY         -- US   198 -15748

The bulletins are in the NGTT dissemination group:
905
SMKB01 NGTT 290600
AAXX 29064
91490 11599 29901 10264 2023/ 40092 60001 70121 82100 333 569//=

Are you really looking for TAF's or were you interested in obs?
