Clearly you are in the know so do enlighten us since you are up there with knowledge apart from radio theory clearly.Hint whilst you are watching cows dump.....Something transmits until it disappears, apply basic maths and bingo...a rough estimate.
I'm confused, I thought you were the expert there claiming that it would have been easy to find the plane by "radio" waves? Which basic maths would one apply to find from which location a plane sent something to a satellite? You can't triangulate it because there are no multiple satellites in play here. And even if you could, the accuracy would be not much better than what was already known as the maximum distance the plane could have strayed from LKP. The rough estimate was there all along without black magic.
There was no radio contact otherwise so I'm not sure where the easy part comes in.
It seems to me that you have formed your own conclusions and then shaped "theories" to fit it but without adhering to actual scientific principles.
