Could it be a whale song?

Whales make sounds beteen 14 and 54 Hz according to wiki, that's a thousand times lower than the black box.

The Chinese were searching well outside the designated search area, a long way to the west of it. If they actually have picked up the pinger off the black boxes, my guess is that they were led to them by some sort of high tech military technology they don't want the rest of us to know they have. It's hard to believe they just accidentally stumbled upon the right location, especially since the pinger only has a broadcast range of about a mile.

A Chinese search plane spotted some debris in that area and that's why they started listening for the pinger there.

Isn't it convenient that a Chinese ship in a random spot outside of the search area managed to so quickly hear the ping for a brief period, that unfortunately they didn't get to record but still had plenty of pictures of the hydrophone equipment and stalwart rescue crew ready to share with the Chinese press? They even heard it a second time, also not recorded, so there can't be any mistake and it must be true! If the source of the ping never gets found, well thank goodness the Chinese saved the day by being around to hear the last evidence that the plane is indeed there, somewhere, before the battery on the pinger finally failed and left the plane's exact position a secret forever.

HMS Echo's being sent to the area to investigate.

Maybe it was too big a risk to fly over Indonesia and the plane simply went from heading west to heading northwest to avoid that and only turned to the south when it was clear of Indonesia. In a nutshell, if someone wanted the plane to turn south but without intruding on Indonesian airspace, then the turn northwest would simply be a necessary diversion that was needed to achieve that.

CNN are now reporting this theory as their latest 'breaking news'. Well done bigglesworth, you beat them to it.

An Australian ship has reported picking up a ping now, but it's 300 miles away from the location of the previous pings.

Hopefully they'll find something off the back of this, as all the conspiracy theories and how badly the Malaysian's handled this from the get go must be hell for the families. Pings in two different areas isn't necessarily an issue as such, if the plane broke up and currents have spread out debris under water, then 300 miles apart in the amount of time that's passed isn't too far. Fingers crossed for a discovery, as the flight recorders won't have much battery life left, as they're only supposed to last 30 days.

how many days left?

I agree with this. I think the Chinese used a method of finding the signal that they don't want to reveal, and the listening device on the end of a pole is just a cover story.
