There seems to be some confusion here......
I was talking about
ULBs and after mentioning the BEA's desire to have the ULB frequency lowered to 9kHz, there was some "noise" about the US Navy laying claim to that frequency. Whether I subsequently made myself clear or not, radio frequency electromagnetic energy is not the same as ultra sound acoustic energy, irrespective of the frequency being the same.
As for AF447's
ELTs, one was found unactivated, and no 121.5/406MHz transmissions were ever detected.
