Hi Bushwalkers.

If anyone is interested, I have a GME MT310 EPIRB for sale. It weighs
210g. This model operates on the 121.5 MHz and 243 MHz frequencies.
From 1st February 2009 the satellites supporting these frequencies
will be switched off, but anyone planning a trip over the next six
months can still get use out of it.

Cheers,
~Dave.

With these instruments going out of date I would have thought it would be
hard to even give them away. I understand the old 121.5/243 MHz models can
be dumped at Battery World shops.
Regards
Bill

While satellites won't be listening out for them, won't aircraft still be
monitoring these frequencies?

Yes, but at their discretion. 121.5 mHz was initially chosen
because it's the civil aviation distress frequency. It remains
so.

Larger aircraft (with multiple sets) are likely to have one
monitoring 121.5 mHz.

I certainly wouldn't count on aircraft listening out 121.5 when ELT freq
has moved to 406. it - if you are going to get an ELT, get one based on
safety (406MHz), not cheapness (121.5MHz) - how much is your life worth?

The new beacons will tx on 121.5, but at reduced power for SAR acft to
home in on. The increased accuracy of 406 means that the search area
will be greatly reduced from what the satellite predicts now.

Agreed and all should understand 406 is not a NEW frequency but has been in
use for yonks.

For $600 you get an Oz PLB with embedded GPS accurate to around 40 metres,
position update 20 min intervals, 121.5 homing signal, and up to 10 year
life/warranty. With your personal details and contact numbers triggered at
AMSA by the (registered) I/D.
Homing on 121.5 is almost obsolete when you have the level of data available
on 406.

Hi Bill.

You'd be surprised actually. A brand new 406 PLB EPIRB will set you
back anywhere from $450 to $600. If for instance you're plannng a one
off outback 4wd trip or long distance bushwalk between now and Feb 09
it's a lot of money to pay for something you don't plan to need again.
For a fraction of that price you can pick up a 2nd hand 121.5MHz
model, and yes, it'll be useless after 1st Feb 09, but it served it's
purpose and cost peanuts... probably cheaper than renting a unit.

Cheers,
~Dave.

Not to mention that many / most PLBs do not meet the legal requirements
of carrying an EPIRB on your vessel. Most will not float right way up
and therefore don't compare to an EPIRB that is designed to do so...

That said, PLBs are great for the use that they are intended for and
that is as a personal beacon... just not the distress beacon for a vessel.

I wonder how long it will be before a technology like bluetooth gets
incorporated in these things so that an onboard GPS or Chartplotter can
send on regular intervals the current GPS fix and devices such as EPIRBS
and PLBs will able to receive and store that data?

Cheers,
Nick.

Also - from memory - prepared to be corrected - the EPIRB is 48 hours vs the
PLB 24 hours.

Worth enough that I don't bet it on a piece of technology.

Be careful where you buy 406 mHz beacons. They are coded with a
country code (transmitted when activated). It is that country
which is responsible for keeping your contact and related
details up to date, and for quickly providing those details to
whatever SAR authorities are responsible for the area in which
an activation occurs.

Paul
Agree with John's post in response to your query.
I have not looked closely at ELT - first because I sold my own aircraft but
more importantly because I'm a believer in PLB.

I believe the Pointer ELT will be available here in October (currently
around $1000 USD) and there may be an Artex also - my tech expert tells me
there is still a dearth of info and product for Oz.

But, for me, the GME or KTI in the pants pocket or my headset bag as I want
the PLB leaving the aircraft with me.
cheers
Brian

Yeah, people should just upgrade to a SPOT.
