Dear LF friends
thanks for your emails containing info about data sent by DCF39 & DCF49.
If you look on www.efr.de, there is a schematic showing the telegram format
which is used by both stations for sending their telecommand telegrams.
My best guess for a identification telegram (DCF49 for example) which is
broadcast to all receivers, would look like in the GIF file attached
I don't guarantee for exactness. The coding of length_byte is still unknown
(message length coded as a decimal or a hex number).
