Have you considered adding a solar cell or two the station. I am using a
much smaller radio, but a 15 watt cell has me battery independent. A 1.4
watt cell maintained enough charge on the gel-cell for me to operate field
day weekend.

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.
