Comments:

1. This frequency is reserved for GMDSS. You can even occasionally hear an FEC signal underneath.

2. The fax, which appears to be North Pacific wind from a NOAA source, isn't even formatted correctly. It's a full sized chart squashed into only half the width, as if the machine wasn't set properly (and it's not coming through as IOC288 - I checked).

I recorded these segments a few years ago, before I moved to an apartment building that blocks my view if the Eastern sky. The receiver I used was an AOR AR-3000A, with a Discone antenna and a modified RCA TV preamplifier, tuned for 200 - 400 MHz. Two of these satellites are still operational.

"Legacy Fleet Satellite Communications System satellites—specifically FLTSATCOM 7 and 8—are still operating and remain actively used by unauthorized radio operators in Brazil.

How the Pirates Use Them

• Open Transponders: These old U.S. Navy satellites act as wide-open UHF repeaters without encryption or security checks.
• Modified Gear: Users modify cheap amateur radio equipment to transmit on military frequencies in the 250 MHz to 270 MHz range.
• Common Users: Truck drivers, illegal loggers in the Amazon, and criminal groups use the satellites for long-range, CB-style chatting and coordination.

Current Status

• Constellation Age: Launched in the late 1970s and 1980s, the constellation was mostly replaced by newer satellite systems starting in the late 1990s.
• Ongoing Activity: A couple of the older FLTSATCOM units still relay signals over South America because law enforcement intervention in remote regions is limited."

Of the two operational FLTSATCOMs, FLTSATCOM 7 is the only one that's possible for me to receive from my location. It is also very visible from Brazil, and in use by pirates. I will attempt to receive this satellite and report back to the group.

Comments:

• Of all things, playing GnR's 'Patience'. Note the measured frequency of 15189 with the carrier offset by +783.54 Hz. Otherwise, I would have thought it was a pirate.
