The satellite system that supports 121.5 MHz analogue distress beacons is in the process of being replaced. Already it is significantly degraded and it will cease operation altogether in February 2009. If you have a 121.5MHz distress beacon which may also be called an
EPIRB (Emergency Position Indicating Radio Beacon), PLB (Personal Locator Beacon) or ELT (Emergency Locator Transmitter) you need to switch to a 406MHz distress beacon.
The above is from a full page advertisement now appearing in New Zealand outdoors magazines. The advertisement is sponsored by Police, Maritime Rescue Coordination Centres, CAA & Ministry of Transport. www.beacons.org.nz
I am sure that if you check with Australian SAR you will get the same advice. NOTE, Feb 2009 is only 106 weeks away!
FACT ! The 121.5 MHz system is failing rapidly and is NOT being replaced, it is being superseded by the 406 MHz system.

We had an 121.5Mhz installed in an aircraft we operated and it does not necessarily rely on a satellite system for it to be detected as it transmits a signal on VHF frequency 121.5Mhz. This frequency is monitored by all RPT aircraft overflying
Australia. So the satellites becoming redundant won't necessarily mean that 121.5Mhz units won't be detected if they are transmitting, but clearly the opportunity to detect is downgraded.
However, if I was in the market for one today I would clearly go for the new generation....

Hi Landy, As an ex commercial pilot I am familiar with the operations of 121.5
In an emergency, an activated 406 MHz beacon WILL be heard and a recovery operation initiated.
In an emergency a 121.5 MHz beacon MIGHT be heard.
Australia is a BIG country. If I had to activate an
epirb then I would like to be assured that the signal WILL be heard.

Yes, that's it Landy, I just want people to be aware of the situation and make an informed decision when spending there $. I have a very good friend who is a manager at a rescue coordination centre and I wish I had the time to tell you some of the real life and recent alerts and real full scale operations that they carry out. They have heaps more operations then the public get to hear about and the time delay before recovery phase for non
epirb events can be the difference between life and death. The time difference between pinpointing the location of a 406 beacon can be almost up to a day quicker then a 121 beacon. To encourage people to change from the 121.5 MHz to the 406 MHz system I would not be surprised if laws are changed to charge people for non emergency activations some time late in 2009 ! (but that's another story).
