Hey hey,
I have just put together a little UDO that encodes numbers into EuroSignal. 
EuroSignal was an old paging system up to 1997. It played special tone 
patterns on the low ultra shortwave band around 87.3-87.4 MHz. You could hear 
these earie unmelodic tone sequences on normal radios, if you went completely 
to the left of the scale.
https://www.dropbox.com/scl/fi/5sq21syrsby9uosad42s0/eurosignal.zip?rlkey=bh59jai4o1n72z5096fs3cfoe

For the longest time I had mistaken these tones for something to do with 
emergency services radio. -- Anyway: it comes with a UDO and a demo file. It's 
dead easy to use and written according to the specification as found on 
Wikipedia. A link is included in the UDO.

This is on Dropbox, so will vanish after a while. I'm still in the process of 
reorganising miscellaneous Csound code into a permanent form.

Best wishes and enjoy,

Jeanette

Hi Richard,
many thanks for the feedback. I'm glad you enjoyed it. A bit of local holiday 
fun and self-therapy. :)

Best wishes,

Jeanette
