Hi Aandy,
A
HF radio is perhaps the most useful communication tool in the bush, but it does take some training to be able to use it properly. A satphone on the other hand is easily used by almost anyone, but who do you call?
I am a member of VKS 737 and one of the things you continuously read about in their member magazine is the assistance of other VKS 737 members who are close by. I have used my HF to log my position during scheds and while "on the side" have been amazed to hear of how close, or far, others are away. There really is a bush telegraph out there and VKS 737 taps into it. Think of how many vehicles you see "in the outback" with a HF antenae hanging off it - all potential rescuers.
Now think of your
sat phone. You can call the RAC, NRMA, 000 or whoever, but how do you contact a mechanic who lives 50km north of
the black stump? If you must make telephone calls, do not forget that a
HF radio can do this, even direct dialling a number! But it is not as simple as using a
sat phone (but nothing that 5 minutes of reading a manual wouldn't teach you).
Now there is also an
EPIRB (emergency positioning indicator radio
beacon). This is a true emergency device, not to be used otherwise. While there is much hype about simply turning it on and waiting for the helicopter to arrive, the reality is vastly different. To cut a long
technical story short, it takes a considerable amount of time (~6 hours) to get a fix and even in ideal conditions it will only have an accuracy of 20kms radius (~1200 square kms - a large place to look).
So, back to your question, IMHO if you are doing "some quite extensive outback travel" you are irresponsible if you do not have some means of reliable two-way communication (either HF or satphone). While I would recommend HF, I can understand the hassle of changing vehicle and hence going for the satphone option. But I would also recommend an
EPIRB, simply as extra insurance. It's a once off ~$250 cost and is a backup in the event of HF/Sat failure.
Cheers
Captain
