MH370

Mysteriously disappears in 2014 and is widely believed to be somewhere in the
South Indian ocean
Loadsa searches but nothing found apart from various stuff washed up that had been
carried far by currents.
Now, this Richard Godfrey chap had a cunning plan and reckons he can plot the planes course
and location more accurately by plotting 'disturbances in the force' of radio signals
used by ham radio geeks caused by the plane passing through them
I have have only the tiniest smidgeon of knowledge on this subject but it sounds jolly clever to me.

YewChube has the usual arseholes and gobshites desperate for clicks who'll naysay him or go down the
gubment conspiracy/aliens rabbit hole just to get attention.
Ignoring these it appears Godfeys theory is being peer reviewed which is fair enough
and people in the know seem to be saying it's worth a look and are cautiously optimistic.
If viable, it may yeild results to narrow down the area of interest from thousands of square miles
to around 300SQKM or 180 square miles.


A possible conspiracy (we all loves a conspiracy don't we?)

The Malaysian gubment who own the airline seem to be dragging their feet over authorising
a new search based on this new approach.
Just some caution? or had they hoped it would have quietly gone away by now
because if the pilot was found to have done a murder suicide, they'd be sued for squillions
with all the attendant stench of bad publicity.

This guys blind tests were wildly inaccurate. Let's see what peer review says.

I have very little confidence this will lead to anything. Malaysia won't want to spend tens of millions searching the ocean without some evidence.

There is a video about this on 60 minutes Australia. I didn't watch it, but you can if you want. It came up once and I skipped
https://www.youtube.com/watch?v=Jq-d4Kl8Xh4

I assume this guy is talking about HAM radio geeks using ionospheric reflection, which is a real phenomena! It is use in over the horizon radar systems which bounce the pulses off of the ionosphere and have a range of upto around 5000km. You can't do it with a home transceiver, you need a big antenna array of poles or towers hundreds of meters long, and tens of hundreds of kW RF amplifiers. The Aussies do have such a radar but they would already know where MH370 is if they had a track on the radar.

You can read more about it here, there is plenty of info about on the subject

You can use ionospheric reflection (skip) with amateur radio equipment and in fact it's been used with 30m (LF) transmitter receivers for years. The skip effect is hard to predict and uses sporadic e layers in the ionosphere that vary with temperature and pressure among other things. It's how a ham in Britain can communicate with a ham in say, Australia without the use of repeaters or relays. The transmission mode is usually single sideband (SSB) with suppressed carrier and morse is normally used to ensure reliability. I'm not sure how variability in the propagation of reflected signals could be used to accurately determine the position of an object given the normal fluctuations of the sporadic e layers and the skip effect - it's rarely that stable.

As you rightly said, OTH radar uses large array antennae and high power to ensure reliability but the principle is exactly the same Smile

There's a fucking huge array right by Chernobyl.....

Yes, it was on Abandoned Engineering. Dugar Radar System. Quite fascinating.

I visited it a few years ago. Very cool.

How and why would that have been recorded?

Windows did for the de Havilland Comet (and Britain’s lead in aviation) and I reckon interior fogging must have played a part here. If only… ®️ etc.

Radio hams log everything.
