@T/S: "to use as a VOR" they cannot, because it doesn't behave like a VOR, it behaves rather like an NDB. Shouting "I am here! I am here!" but without adding any directional information, which is the essential advantage of a VOR over an NDB. And by the way your PLB and ELT will be doing the exact same thing if/when activated (plus they may be adding useful information such as GPS-derived coordinates).
But it has rightly been stated that, among an impressive load of equipment, the rescue crew are bound to have some kind of direction finder which they can apply to anything you are transmitting with. With particular attention for the civilian distress frequencies of 121,5 and 406 MHz. They may even well be able to home in into your mobile phone.
