Interestingly 121.5 / 243 MOB devices can still be activated.
Anyone know the difference in the transmitted signal between a 121.5 EPRIB and the 121.5 MOB device (perhaps the modulation?).
As far as I can tell from the radio communications act (in Oz), 121.5 Mhz still remains a legitmate distress frequency.
