Well I just posted a reply to your query and then looked up the site about
repeaters on the net.
http://www.telstat.com.au/uhf_qld.htm   lists Qld and infact all of
Australia repeater channels.
http://www.telstat.com.au/uhfworks.htm  Gives you an idea how to set up your
UHF to repeater mode.
Anyway I am not very technical I just know we use it when we are out there.
Good luck
Kathy.

Kathy,

Many thanks for the link to the repeater sites.  Greatly appreciated.

I leave about next Wednesday, but I starting to get psyched up
already!  Weird...

 Not really ,(Frankinferter said it so well "ANTICEEEPATIONNN" )

 you might consider getting a ham ticket at a later date , easy to do
now , I have been talking to a guy on 40 metres who has driven from
Victoria all across Kinarvan area and has now headed out your way
somewhere over the last several days , just great reception and like a
radio phone ,

What would a ham radio cost these days and who sells them?

Where do you enquire about the licence?

you can pick up an hf set from a couple of hundred dollars , a grand
will get an almost new set , vhf uhf from $60.00 for handhelds on e-bay
 Where are you  and I will find a club close by or go to
http://www.wia.org.au
 they only rep about 25% of the hams but they have uses.

Will all HF radio's operate on both the 2m and 40m bands, or do you require
a different set for each?

Older sets you  need one of each ,  sone if the new sets like the ft857d
will do both.

Dos it come with one of those big fat aerials? I've always reckoned that
gives you more bloke cred than pissy UHF ones. :-)

Does anyone remember a thread 3-4 years ago about when I used my UHF in the
Gulf and got onto the RACQ 120 K's away?

Apparently it was impossible to do, so I was full of sh.t for claiming that
I did.

Anyway.........if HF's are as cheap as that, I think I'll invest in one.
When I take the kids outback, I reckon it would be good "insurance". I know
from when I worked in Nth west Qld, good communications were a matter of
life and death sometimes. I'm assuming these rigs can contact the RFDS

They may operate on rfds,  I don't believe it is normally legal to do so
unless in an emergency , but for everything else very useful .
 you can find the odd Codan on ebay with rfds installed .

if its a once-off trip you may be able to rent a satellite phone. My
in-laws are off today for a couple of weeks in their camper and with the
sat phone can emergency call from anywhere.

I feel compelled to jump in at this stage. Not ALL satphone services are
reliable. I could have died 20 times over waiting for Globalstar to get
their act together. They advertise that you can jump tall buildings in a
single bound but the truth is that their *service* is both unrelaible and
their advertising misleading. Furthermore they ignore any correspondance on
such matters.

Very interesting comments Jim, and thanks.

As a boatie, most of us who plan on venturing out past the VHF limits often
discuss the idea of Sat phone Vs HF.

Sat phone always wins the argument hands down, but I have never heard anyone
mention what you just did.

That certainly throws a new angle on it for sure.

How often does this happen?

Gary, just caught up on your post sorry. I have many posts elsewhere saying
that others have had problems. But talking to the service providers it
appears that it *might* be a coverage thing at the moment. What I do know is
that the Ericson R290 phone is the main culprit, and that coverage is
currently patchy at least in the north and west of Oz.
My advice would be to "try before you buy" if at all possible. Hire or
borrow one and use it where you normally need one.
Cheers

Barnsey,

We have held conversations with other properties that were over 140 kms away
certain mornings.  Last time I recall, it was a fine, cool, damp morning just
after a week of rain.  It was clear(no cloud), but there was obviously some sort
of skip happening. We held a conversation with the other station for about 15
minutes before the 'skip' faded.

Also, we regularly hear both the Tambo and Winton repeater on cool, damp
mornings here.  Both repeaters would be over 200 kms away direct.  I doubt we
could reply to them, but we can hear them...

If you can wait a few weeks, I can get you an HF(Codan 8525) for the right
price(like SFA), if you like. However, you'd have to sort out an antenna for it.
Neighbour has a leftover from his kids School of the air(now all satellite), but
it apparently has RFDS freqs still on it.  I can find out if you like, but it'd
be 4 weeks before I can send it to you.

Personally, I'd find a sat-phone more usefull to me, but the HF would be a lot
more social, as well as a lot cheaper. Probably easier to get someone local to
come save you as well...

 from the conditions you describe it dount its "skip" more like
extended ground wave  , I am willing to be you have a setup which has
fitted into certain criteria for "gettingout" in particual the aeria is
at just the right height which isn't always super high .
 Barnsey should consider the codan as they are an excellent and usful rig .

kind of you to offer .
 Never rely on sat phones , in the years I have had them availible
there has never been any certainty although things are better than a few
years ago.

Temperature inversion or Tropospheric ducting

when a cold layer of air is trapped under a warm layer(temp inversion)
it makes an RF tunnel where the VHF and UHF radio waves get trapped and
reflected along, usually in just one path direction

and a cool humid morning is usually when it happens
200klms is quite achievable

channel 2 repeater in Brisbane is sometimes wiped out by the channel 2
repeater at Gunalda about 200 klms north(about 35klms nth of Gympie)

When in NZ I run an AM set that had unbeleiveable skip one Boxing day.
Wellington to Gore (Some 800Kms South). Positions backed up with Mobile
phone call to land line.

Never had that kind of skip again. And that was with a 4 Watt set as well.

Go figure?!?!?!

Yeah different type of skip Scotty
that has to do with sun spot activity and the ionosphere(11 year cycle,
of which we are now at the bottom of, another 6 years will see those
conditions back again)
back around 86 I could talk to Hawaii with  nothing more than a 5 ft
fiberglass andtenna on the car and my trusty Uniden AX144 sideband

the inversion is a weather related type and mostly affects VHF and UHF freqs

In '77 I was driving around with a 40 channel Phillips side bander in
the ute ( v8 xy) on 27 + mhz talking all over the wold on very low power
. to do that now I need to run the 12 ft screwdriver , a 35 amps
amplifier and a 100 watt exciter with a preamp on 40 meters, I look
forward to the sunspot peak.

Barnsey, theres an offer not to be refused!!
Get that and and worst case buy a new antenna for $200 and you are in
business. That and the fees to join VKS-737 who now have Aus wide coverage
and a membership of thousands and you cant go wrong. The coverage they offer
is the insurance for your family and your gear throughout Aus, the CB is
handy but the Codan will perform all the time anywhere.

Buggar off ya bloody Mexican!!!  .-)

This is a Qld thing, stay out of it!

Of course, I'll pay freight and remuneration in 4x for Rods efforts. Hell, I
might even do a road trip to pick it up and assist Rod with the 4x. I'm
always looking for an excuse for a road trip outback, but realistically,
postage will probably be the go.

Very grateful for the offer, once again.

Barnsey,

I'm heading off down the Birdsville track - SA - Vic, etc for about 4 weeks
tomorrow, and will do something about the radio when I get back.  

Dont stress; it's yours.

I was under the impression it had the RFDS channel fitted, but the neighbour's
now not sure.  It would only be a matter of a radio bloke fitting the correct
crystal.  There is also a base antenna (basically 3 long runs of insulated
wire), but I'll talk to you when I retrieved the radio and checked it out.

I give you a heads-up on my return.  

Cheers,

Rod.

Those Codans are EPROM programmed and can have I think at least 100
channels programmed in, so anyone with an EPROM programmer can do it

No there's a rare beastie these days...

Thing is, I've got one, so if someone can tell me what sort of EPROM
and what to burn onto it, I'm happy to burn an EPROM or two for Barnsey.

Given that these things are supposedly recent tech, are you sure it
isn't an EEPROM? (I don't have a burner for those).

If it's an EPROM it should be a standard looking electronic cockroach
except for the transparent window in the top centre (used to erase the
things with UV).

The Codan 8528 uses a 512 eprom. There are three options availiable in the
programming , depending upon your availiable software. *Normal*, Amateur and
Option E which allows front panel selection of frequencies. This option is
frowned upon by authorities in Oz for obvious reasons.
Although the eprom can be burnt with just a burner, changing a profile can
only be done with the Codan software which dates back to the 1980's.

Which I think I have a copy of here somewhere
and yes I do have it
with a couple of .bin files for the burner

I have also heard that you can in fact upgrade the 8525 to an 8528 but
it requires a bit more than just a simple eprom
the head unit is one

Actually Kev, you can only upgrade the 8525B to a 28, not an 8525A.
Different internals. To upgrade the 25B to a 28 requires a 28 remote head
(scarce as..I'll buy half a dozen if anyone has em :) and change the profile
of the 512 eprom to a 28. If wanting 27 or 28 meg you'll also need the low
power loom.

FARK YEAH! I cant say no to an offer like that!!!

How do I get in touch, Rod?

The conditions you describe about UHF comms are about right for that night I
was in the gulf, by the way. Cold night, clear sky.........

One of the mining jobs I've applied for will require me to drive 30 Ks past
the Lynd and back (week on week off roster). I've driven that road many
times, and had a few dramas, ranging from tyre blow outs to attending to a
car accident victim. So apart from having reliable comms for my family
trips, I'd feel more secure knowing I could get the RFDS etc........
