Hynix found possible 8th bit in it
the 2 line is at 2.5k Hrz
http://vocaroo.com/i/s0z44qm6m4dq --- 2 Line separated
if you compare your spectro to http://pastebin.com/M8fBC9WM (and move 392 to the beginning) you can see that last bit on yours ("2") is not present on ygves pastebin


CHAT LOGS with explanation how to decipher it

[00:44] AluisioASG ==========\\_ABISM\\_==========\\_REQ>@\\_REQ>@\\_REQ>@
[00:44] AluisioASG YEAH!
[00:44] Ymgve how
[00:45] AluisioASG DEC SIXBIT + mark parity
[00:45] AluisioASG "One popular variant was DEC SIXBIT. This is simply the ASCII character codes from 32 to 95 coded as 0 to 63 by subtracting 32; it includes the space, punctuation characters, numbers, and uppercase letters, but no control characters."
[00:46] AluisioASG 392 is mark parity; if it's not there, then there was a transmission error.
[00:46] Ymgve it's not really parity then
[00:46] Ymgve just a stop bit


[00:48] Ymgve also I think you got it wrong, I think \_ is actually some CRLF thing
[00:48] Ymgve carriage return

http://pastebin.com/M8fBC9WM

[00:48] AluisioASG Read them as bits (in the pastebin order); ignore the 392 column; add 32 and interpret as ASCII.
[00:50] AluisioASG right (line 1 is 0111011)

[00:58] AluisioASG So, are we supposed to answer in 17201?
[00:58] Adah How did we decode it, btw?
[00:58] Adah You don't have to tell me if it's really long and involved, haha
[00:59] crash_demons Adah, even frequencies, six character bits.
