You are a lying Tory Abbott clown

Due to Telstra not being able to keep most of it's aging copperwire repaired

That is a bare faced lie. Literally millions of DSL users use it fine every day.

(I'm in Sydney)

Literally millions of DSL users in Sydney use it fine every day.

broadband Internet via copperwire is just a lying joke.

You are a pig ignorant lying joke.

I have "4G" wireless called HSUPA.

HSUPA is 3G, not 4G
http://en.wikipedia.org/wiki/HSUPA

Seems to work as long as there is a tower in each short street

Works fine even without that.

each tower feed by optic fibre VERY dependant
on a limited amount of users accessing that tower.

Yep, that will always be the main downside with wireless.

At present when kids are home instead of school it becomes useless, intermittent.

Its nothing like as black and white as that here with nothing like that density of bases.

No way is wireless able to replace a GOOD landline connection.

Depends on what you call good.

It most certainly backs it up but COMPLETLY useless as only alternative.

Depends on what you want to do with it.

Removing the politics Australia's copperwire is crap,

That is a bare faced lie. Literally millions of DSL users use it fine every day.

only maintained where it's economic to do so.

Another bare faced pig ignorant lie.

For infrastructure reasons alone it needs replacing.

That is a bare faced lie. Literally millions of DSL users use it fine every day.

This will be done at a cost

No it wont, because the plug will be pulled on the gillard govt in a maximum
of 2.5 years and when that happens, thats the end of the NBN and any real
replacement of copper, if any replacement of copper ever makes it past the
approval of the Telstra shareholders and the ACCC anyway.

I don't know if this cost is recoverable

Corse it is.

but it needs to be done

That is a bare faced lie. Literally millions of DSL users use it fine every day.

and Testra is not going to do it or at least all of it

You did get that right, because it doesnt need to be replaced.

In most cases this is happening now where replacement
or new suburbs is being done already with optic fibre.

Another bare faced pig ignorant lie.

Copperwire has become old history.

Another bare faced pig ignorant lie.

You can also get cfls that work direct off 12V. I have some in a shed on a
property and they are excellent. 3 x 25W units light the 6x6m shed very
nicely. Usually I just run the one light.

If you need to run it off 12v, like a battery or car type install,
looks like you would need to step
it up to the 32-36v required. Otherwise you will need to use a mains
supply to provide the voltage

That bit I figured out for myself

required. This would be a pain as power supplies with this output are
not commonplace.

That I'm not so sure about. Trevor said it would be easy tho

they're not that hard to come by, just a little pricey for bunnings.

Nope, the return on that capital isnt anything special.
You can get that in a bank deposit with a govt guarantee.

but not the massive profits created by the Labor incompetents simply to buy some cheap headlines.

They didnt do it to buy cheap headlines, they were actually stupid enough to think it made sense.

AND its a GROSS feed in tariff too, you get paid that even if you use the electricity generated yourself too.

Just plain barking mad and a large part of the reason we have seen our electricity bills hike so dramatically.

*if* it's a straight coil of wire with an air core, then Wheelers formula

1/4" whitworth and 1/4"unc are exactly the same. They are

interchangable. 1/2" is the only size where whitworth and unc are not
interchangable (the thread pitch is different).

Short bolts with thread all the way down are available, they are called
set screws and in 1/4" size should be readily available down to 1/2" length.

Most 1/4" hardware is common in zinc plated finish. Stainless steel is
also common.

Are you saying that, when the NBN is being used as a broadcast network
by a multicast TV source, NBN Co will have to switch the signal to
each subscriber and block it to those that don't subscribe? That is
certainly not how the HFC network works. It would explain why you
believe that "cable" TV over the NBN will not require a set top box.

How does the NBN network differ in this
regard from free-to-air or cable TV? They all require a single media
source and multiple destinations.

A broadcast network only requires a single circuit to reach multiple
recipients.

_Every_ network requires a circuit from the source to each desired
destination. I suppose that a ring topology might be regarded as a
"single circuit" but that is not the network model being implemented
by NBN Co.

Or did you think they broadcast Free to Air TV just for you?

On the contrary. There is a circuit from the transmitter to my TV
aerial and a circuit to every other aerial in range. If you happen to
be confined to a Faraday cage there will be no circuit and you will
not receive FTA TV.

No, the NBN has absolutely nothing to do with it. Managed by the ISP
that gives you access to the multicast channels.You don't have access to

believe that "cable" TV over the NBN will not require a set top box.
How does the NBN network differ in this
regard from free-to-air or cable TV? They all require a single media
source and multiple destinations.

A broadcast network only requires a single circuit to reach multiple
recipients.

_Every_ network requires a circuit from the source to each desired
destination. I suppose that a ring topology might be regarded as a
"single circuit" but that is not the network model being implemented
by NBN Co.

FM radio is "broadcast". Walkie Talkie's are "point-to-point".

Walkie-talkies are not point to point they are broadcast as anyone on that
frequency in range can pick up that signal

Normal TV is "broadcast". Fibre is "point-to-point".



Or did you think they broadcast Free to Air TV just for you?

On the contrary. There is a circuit from the transmitter to my TV
aerial and a circuit to every other aerial in range.

One, single circuit for every user. Unlike point-to-point media like
fibre.

It makes no difference that fiber or cable can be used for TV

If you happen to
be confined to a Faraday cage there will be no circuit and you will
not receive FTA TV.

No, the NBN has absolutely nothing to do with it. Managed by the ISP
that gives you access to the multicast channels.You don't have access to
the NBN, but just a VPn back to your ISP, like now.

NBN is indeed a TV broadcaster, transmitting on Channel 3 and digital
channel 8.

Can you explain that since it doesn't seem to be listed anywhere?

Apart from the fact that it wasn't what was being discussed.
