||     Some of the practices and methods described in write up may be illegal      ||
||     in your area. Even though Iridium transmits in plain text it still may      ||
||     be considered a crime to record and decode. Please use your better          ||
||     judgment while playing with this tech. If you live in the US please         ||

||     If you want to save money with the antenna and LNA, you can hack a $10      ||
||     active GPS antenna by removing the filter and bridging the transmission     ||
||     line (Or replacing it with an L-Band filter). The image below is an         ||
||     example of a hacked GPS antenna.                                            ||

||     Just a heads up but your mileage may very. Because these active antennas    ||
||     are built cheaply they may fail right after you mod it. For your reference  ||
||     the image bellow shows what a bad active antenna looks like in a FFT with   ||
||     the Bias Tee on.                                                            ||

||     To decode the packets captured by gr-iridium you’ll need Iridium Toolkit    ||
||     and the AMBE decoder if you want to decode voice. You have two options for  ||
||     the AMBE decoder, you can either install the open source version            ||
||     (osmo-ir77) or rip the codec from commercial firmware. I’ve had more        ||
||     success with ripping the codec, however I’ll go over both processes.        ||
||                                                                                 ||

||     This was just a quick and dirty example on how you can surf the waves of    ||
||     SIN by poking around Iridium! :D                                            ||

||     I encourage you to read up on Iridium and to review the source code to      ||
||     see how this all works. I would also like to thank the MUCCC for            ||
||     maintaining this code and making this possible for us to explore satellite  ||
||     communications!                                                             ||
