KIFIS:
As I mentioned previously it does appear to be Chinese Telegraphic Code (CTC) in format.
Unfortunately it seems all the Chinese GF hosties are too shy to respond to my request for help in translating the Chinese to English now that I have got that far; or maybe my 'rep' is too well known and they are staying away on purpose!
Anyway, I have befriended a young lady who works for a big (aviation) telecoms company in SIN and she is going to help me (to help you).
I hope to have the plain text within the next two weeks (this is assuming that we are talking about a straight substitution and no further encryption was used).
I hope to be in SIN end of next week, so give me a few days after that and hopefully all will be revealed.
