The problems with a satellite solution are cost, weight and power. I want to
be able to carry the whole thing backpack for several hundred km and for it
to operate on battery power. There is a commercial HF SSB station in Sydney
for marine radio - it looks like I would be using this if I was in the
eastern states of Australia (ultimately I want to do an extended trek along
the Vic/NSW alpine trail). This is mainly remote mountainous country with
occasional 4WD tracks and roads and very few settlements. I have loked at
the SSB radio options - the best seems to be the SCS transceiver, but Rx
current is still 100mA.
I would probably use a PalmPilot as the computer part with an interface to
this. Here in WA there doesnt seem to be any options (we are 3000km from the
eastern seaboard). All in all a big project!

No doubt this is an easy question, but is there a way of interfacing to

the

web via HF SSB/data?


I want to be able to do this from a remote location portable/backpack

with

no mobile phone access and low power. The nearest infrastructure could

be

several hundred km away


I could use amateur bands or possibly a commercial solution if

available.

What would be the data format and where would I get more info on this?



This shoulds like a job for a satellite. If worst comes
to worst, plug a modem in to a satellite phone and dial
up your ISP...

The first UoSATs were for exactly this sort of application:
take a briefcase-sized station in to the field and send
chitchat back to home base by satellite, completely
independent of terrestrial infrastructure, which may not
exist anyway.

We have satellite Internet here in Canada. It isn't cheap.
