240RS:
Does anybody have any info on the 1/6 forward error correction code they can use. He mentioned the symbol (or signal?) power can then be some dB below the noise level and still be decoded. I know this is true in theory, but would love to hear more.

Thanks! Done

"A series of planned commands sent to NASA’s Voyager 2 spacecraft on July 21 inadvertently caused the antenna to point 2 degrees away from Earth. As a result, Voyager 2 is currently unable to receive commands or transmit data back to Earth." source  :palm:

NASA bungled that one. Hopefully in October the spacecraft successfully runs it's routine to scan but it's pretty old and I wonder how the SRAM is doing.
