I'm still\ndigesting the info.\n\nTL;DR: I heard automated packet transmissions on the ISS packet frequency\nwhen the ISS wasn't in sight and recorded them to try and figure out\nwho/what they are, but my software isn't decoding anything.\nCan you help me understand what they were, or even better, decode them\nyourself?\n\nhttp://cupcakecarnival.net/sites/default/files/New_Jersey_Terrestrial_Packet\n_145825_2015-04-30-1540_UTC_one.wav\n\nhttp://cupcakecarnival.net/sites/default/files/New_Jersey_Terrestrial_Packet\n_145825_2015-04-30-1540_UTC_two.wav\n\n\nHere's another question that has me excited:\n\nYesterday after having visited with family in Maplewood, New Jersey for\nseveral days, I drove home to North Carolina. I knew there was an ISS pass\nat 10:26 AM/1426 UTC, right when I started my trip, so I tuned to 145.825\nMHz and heard its digipeater easily.\n\nThen I left the radio on.\n\nI'm not sure where I was in NJ, but about one hour later, around 11:33 AM\nlocal/1533 UTC, I heard packet on the frequency again but I was confused\nbecause there weren't supposed to be any more passes for a while. I\nconfirmed on my phone that the ISS was over some far away ocean at the time\nI was hearing these new transmissions, so I knew they must be terrestrial.\nStill, it seemed odd that someone or something was transmitting when the ISS\nwasn't in sight...\n\nMaybe it's an internet gateway I thought. Or do people leave their stations\non the ISS frequency 24/7 so they can \"work\" any pass that happens?\n\nI tried recording videos of the transmissions for later decoding to figure\nout who or what it was. Eventually I realized it was transmitting every 2\nminutes. It was almost certainly an automated setup, adding credence to the\nidea that this was an internet gateway.\nUnfortunately, before I realized that, and after recording one video of it,\nthe best reception I received during my drive by \"pass,\" I wasn't recording.\nAs I drove further away it only got weaker and weaker. I did manage to get\ntwo half way decent recordings of it, but I have tried decoding them with\nSoundmodem on Windows and it's not printing out anything like it normally\ndoes. I am very new to packet, only becoming interested in it because the\nISS uses it, so I thought maybe someone else might be more equipped to\ndecode it. Or certainly someone could shed some light on what I heard, maybe\nthe operator in NJ is on this list.\n\nI used Audacity to record the audio off the videos I made as well trim and\namplify the audio, but I haven't done anything else, though if someone wants\nthe unedited videos I can put them up too.\n\nhttp://cupcakecarnival.net/sites/default/files/New_Jersey_Terrestrial_Packet\n_145825_2015-04-30-1540_UTC_one.wav\n\nhttp://cupcakecarnival.net/sites/default/files/New_Jersey_Terrestrial_Packet\n_145825_2015-04-30-1540_UTC_two.wav\n\nJohn Brier, KG4AKV, Raleigh, NC, FM05\n_______________________________________________\nSent via [email protected].
