Interesting theory.

While doppler might have accounted for the frequency shift I found it hard to believe that a XTAL locked signal would have more than 10% error in the pulse rate.
Considering the S/N ratio they were pushing the receivers to (probably equiv to 1PPM or perhaps a fraction of a dB) - I think the 'pings' were an internal physical or electronic feedback loop from some extraneous circuity or ships machinery that showed up on their receiver circuit.ecureilx wrote:I really catch no ball ...PNGMK wrote:Those false pings were interesting.

but did anybody explain the false pings?
confused ....
that explains a lot ... notPNGMK wrote:[]

Legal speak, if they don't declare it as an accident, for the time being, the Insurance companies will not process the claims, pending a resolution, and culpability (I hope that is the word .. )Brah wrote:I just don't get how they can call it an accident.....
