Hi Arslan,<br>
<br>
A while ago i tried to write a software modem to communicate between
2 freerunners.<br>
One of the things that went wrong was a 90 degree phase shift in the
audio signal.<br>
So when you write audio software, please keep in mind that it might
get phase shiffted.<br>
<br>
Kind regards,<br>
Ed<br>

<div>@Dave... Encrypting gsm is legal in our country, and as far
as i think encryption shouldn't be illegal coz voice/data is
your private property so protecting it further shouldn't be a
problem with anybody as long as it doesn't affects their
systems.<br>

Hi,<br>

I don't know the laws of your country, however, encrypting
GSM might be illegal.<span class="HOEnZb"><font

There was already somebody who developed a program
to do encrypted GSM calls<br>
with two FR. But i don't remeber who it was.<br>
<br>
But one should find something in the archive of
this mailinglist.<br>
