The way I see it, it is not very quiet, you just need to be position at exact angle to hear it, the way I do it is I play the signal, then whilst the link is playing I position my ship so I can see "the speaker", then move it in small increments until I hear the code. I try to be around 50 m away. Any ship will do, but I prefer Asp as well.
Way to go contradicting me there, thereby setting you up with an opportunity to patronize me. Now you look like you know more than me about everything, not just about Unknown Links in Elite Dangerous. I already said I was looking down the UL's throat and could barely hear the UL message. In fact I was 31m from the UL, and by contrast the sound of my own Unknown Signal playback was painfully loud by comparison.
Now I also said I understood all the maths, meaning I understand binary and octal. I also understand that the three UL responses to the three Unknown Signals are alleged to represent distance readings of the next system containing an Unknown Site, respectively from Merope, HIP 14909, and Col 70 Sector FY-N c21-3, measured in multiples of the distance between Merope and Col 70 Sector FY-N c21-3 i.e. 871.012824 L-y. This they do by each producing successive groups of three binary white noise pulses, a higher-pitched noise for 0 (zero), and a lower-pitched noise for 1 (one), sometimes separated by a single warbling pulse for / (division stroke). Each group of three binary digits represents a single octal digit. Thus each series of pulses transmitted in the UL's response to each Unknown Signal represents two octal numbers separated by a division stroke, giving a distance figure as a decimal fraction of the distance between Merope and Col 70 Sector FY-N c21-3.
What I don't understand is how this information is being used to find the next system with an Unknown Site, and the next one, and the 200-odd systems with Unknown Sites claimed to have been discovered using this data. No one has offered any explanation at all, beyond 'it takes degree level maths'.
I know I'm late to the party and no one owes me an explanation on that account, but there should be an explanation anyway. And besides,
I am that guy, you know, the one who points out stuff that no one wants to know about....
My own limited maths, as applied to the first of the HIP 14909 Unknown Signals works as follows:
Unknown Signal 1:
Binary:

001 / 011 001
001 110 101 001 / 001 111 101 010

Distances from Galactic Co-ordinates:
0.151 × 871.013 = 131.52 L-y from Merope -78.59375 / -149.625 / -340.53125
0.04 × 871.013 = 34.84 L-y from HIP 14909 -84.375 / -259.28125 / -358.65625
0.935 × 871.013 = 814.40 L-y from Col 70 Sector FY-N c21-3 687.0625 / -362.53125 / -697.0625
[I have a formula to try to work out the Galactic co-ordinates of the next system using the co-ordinates of Merope, HIP 14909, and Col 70 Sector FY-N c21-3, and their calculated respective distances from the system given by the Unknown Link:
D = √ (
x -
a)² + (
y -
b)² + (
z -
c)²
Where
D is the distance of the reference system e.g. Merope,
a,
b, and
c are the X, Y, and Z Galactic co-ordinates of the reference system, and
x,
y and
z are the Galactic co-ordinates of the next system we're looking for.]
√ ( (
x - (-78.59375))² + (
y - (-149.625))² + (
z - (-340.53125))² ) = 131.52
√ ( (
x - (-84.375))² + (
y - (-259.28125))² + (
z - (-358.65625))² ) = 34.84
√ ( (
x - 687.0625)² + (
y - (-362.53125))² + (
z - (-697.0625))² ) = 814.40
(
x + 78.59375)² + (
y + 149.625)² + (
z + 340.53125)² = 131.52²
(
x + 84.375)² + (
y + 259.28125)² + (
z + 358.65625)² = 34.84²
(
x - 687.0625)² + (
y + 362.53125)² + (
z + 697.0625)² = 814.40²

And that's as far as I've got. Anyone care to explain to me how to solve these polynomials, and show exactly how they triangulated the next system from the UL response data? Or may I assume that mathematics ultimately only serves to cover a multitude of secrets, lies and sins? Like Devs creating game content so obscure that only the Devs and their buddies can access it. I mean, what sort of game includes ultimately pointless puzzles that require the exercise of degree-level mathematics to complete, but doesn't fulfil most of its promises (exploration) and gets basic things wrong like a faulty outfitting screen which requires the navigation of nested text menus, instead of a simple drag and drop interface? Etc., etc., etc. Don't you get the impression that the Devs are making fun of you?
