I just got this on my emailed CNN News bulletin, but can’t find confirmation anywhere else:
Chinese ship discovers pulse signal with frequency of 37.5 kHz in southern Indian Ocean, state news agency Xinhua says.
According to Hydro International, that’s the right frequency for a “black box” (my emphasis):
All commercial air transport (CAT) aircraft are fitted with underwater locator beacons to assist in the relocation of black box flight data recorders (FDRs) and cockpit voice recorders (CVRs). These beacons are free-running pingers transmitting at an acoustic frequency of 37.5kHz with a claimed battery life of at least 30 days.
I hope this doesn’t prove to be one of the many false alarms, for the relatives and friends of those aboard the Malaysia Air flight have had a horribly emotional roller-coaster ride. I suspect, however, that this is indeed the plane.

UPDATE: As one reader noted below, the ABC News said this:
The signal was detected by the Haixun 01 vessel around 25 degrees south latitude and 101 degrees east longitude, the Xinhua agency reports.
However there is no evidence so far that the signal is linked to MH370.
I’d say, however, that since the signals last only 30 days, and there’s no evidence of other planes having gone down in the area in the last year, this is evidence linking the signal to the Malaysia Air flight.
