Hi Eddie,

Did you ever put numbers to the data units?
080905.jpg is familiar to us as a breakfast or tea time 3 unit code,
reading 6,11,12
0080906jpg is more complex 3,8,6 - 6,8 ---- 9,11,10 - 12,4
This has confirmed some as yet unused (unseen by me) data units which
I had surmised were there and useable.
I didn't try to 'see' anything there, I am not even sure how many
different 'tones' they actually send. But it doesn't seem that much,
only a few bits per symbol.
The filenames use the date in ISO 8601 format, which I often use for
temporary filenames.. YYMMDD . With a full year number, the dates were
2008-09-05 and 2008-09-06. Not sure if the timescale was in UTC or local
time back then (but compare this with Markus' post, the schedule seems
to be the same still). I don't remember what happened on September 6,
2008, why they sent so many 'data bits' around and after noon. It's a
pity my recording ends before the transmitter switched back to the 82 Hz
idle tone on that day.
73,
