Calling all scientists and mystery seekers!
The Children of Raxxla would like to bring another mystery to the attention of the general public. To solve it, we might need the support of as many CMDRs as possible: the Station Antenna Hidden Transmissions.
By analysing the audio recorded close to any orbital station antenna, you see spectrograms like this one:
What have the Children of Raxxla found out so far?
- you can get these recordings in large stations as well as outposts
- recording outpost audio is easier, because you don't have to land
- approx. 9 letters are sent per minute (one every 6.7 secs)
- so far, we have put together the following draft alphabet (pdf) . This covers all symbols found, but it's next to impossible to identify the differences between I/L/J/T or E/F
- the cipher stream does not have any obvious breaks, nor repeats (within 60 mins max recording time so far)
- a transcoded cipher stream from Walz Dock in Bunda (random pick) seems to have a random letter distribution
- optimized spectrogram settings:
Where we are asking for help:
- we need better spectrograms to identify all letters clearly
- we need more recordings / transcodings to find repeats and non random data
- we need more recordings from different systems: some may contain actual non random data
We couldn't find any previous work on this mystery, so we apologize in advance to anyone who can claim earlier findings. Please share them!
