DARLING DOWNS RADIO CLUB

vk4wid@...

Hello and welcome to the weekly update from the Darling Downs Radio Club.
I'm Secretary John VK4JPM. It's GroundHog Day, so I've checked with
Punxatawnie Phil and we're either in for another four weeks of Queensland
snow, or this segment will replay over and over again until the next Club
meeting on Monday 10 February.

Speaking of which: Bruce, VK4MQ is preparing for the session on Fox
Hunting with ever more interesting do-it-yourself tools. He has just
completed a signal strength meter that you can build for almost nothing -
seriously, since the key expanded meter component is a Chinese module
costing $6 or less. Bruce also promises to describe how you can make a
directional antenna in one hour with easily available parts for under $5,
and he's worked up a seriously high-Q 2m filter at a similarly
unbelievable price.

The message here is that you can get into Fox Hunting without spending a
lot of money; you can have a heap of fun in an only slightly competitive
field, and learn so much about radio and electronics in the process.
That's a really important reason for our hobby, and Bruce is keen get you
up to speed.

Come along and plan to have your horizons expanded, because that's what
club meetings are about. That, a beverage or two with friends and some
timtams. It's on the 10th of February starting from 1900. We meet in the
Toowoomba Library, level 3, with tons of undercover parking in the
basement, so even if it did snow in Queensland you won't get wet.

At Darling Downs Radio Club we believe that being social is an important
part of amateur radio, so a reminder about our bi-monthly informal lunch
this coming Saturday February 8th. We'll be meeting at Cafe Inferno in
the Southern Hotel on Ruthven Street Toowoomba, just a bit south of the
CBD. All very relaxed, and the menu still includes the great value Six
Super Saver Specials menu. Highly alliterative, and very tasty. You
can't go wrong. Again you'll find address and more details on the club
website, and it would help if you register via email to
lunch@....

Now, a few upcoming events. There's a WICEN event in Southbrook on
8/9/10 March; the John Moyle Field Day over the weekend of 15-16 March;
and pop Saturday 10 May in your diary for the Club's first annual FoxHunt
and social BBQ.

Did you get all that? No? Not a problem. All the details about club
events are on our website at www.ddrci.org.au, and click the "view detail"
buttons to get... more details. We welcome out-of-towners and non-members
to our events - if you're planning to travel in then let us know so that
we can set the red carpet for you and *your* guests.

Finally: if there's anything that's still a problem, feel free to blame us
and get it fixed by sending an email to secretary@... - the same
address for making general contact with the club.

Until we meet again next week, it's 73s from John VK4JPM and all the gang
at the Darling Downs Radio Club.

Hello, I’m Geoff Emery, VK4ZPP, and I’ve been thinking.

The technology that we use depends on what is generally called a
commodity and which we pay for in increasingly high premiums, that of
electricity.

Mostly we are supplied by a reticulated service and the electrons
are persuaded to travel the network in various ways that we call
generation. We seem to have seen a total revolution as batteries were
the first way of making electricity available, then came
electromagnetic generation with various forms of energy providing the
mechanical forces to rotate the magnetic fields and we have now
revived the storage battery to facilitate use.

Various uses of electricity have occurred over the last 3 centuries
or so and the latest fad which has swept the share market speculators
off their feet has been that of artificial intelligence. AI was
undergoing an ethical analysis as to the limits of its uses and the
capacities it should be allowed to develop and then ChatGPT was
launched on the world. Shares in the “chip” manufacturer, Nvidia,
soared but not as high as the fictional cryptocurrencies. Then this
past week a new player with reportedly fewer demands on computing
power lobbed into view and the stock exchanges reeled.

Before the release of the Chinese developed AI app, there were
questions as to whether the electricity grids could meet the high
demand of the data centres which hurled the gazzillions of terabytes
of data into the internet to make AI work. Then some cheeky
environmentalist types added further to the debate by querying the
amount of water that the data centres demanded to maintain suitably
cool environments for the computers to make the magic.

What we saw in the development of electricity as a necessary tool is
the benefits of economies of scale. As more people were able to access
electricity, the costs of providing it fell until somewhere in the
last quarter century the western world lost sight of the things that
are useful and renamed them as commodities. Utilities such as water
and electricity were processed and supplied at sustainable costs but
when controls were relinquished, and plants were sold off the prices
rose.

With AI becoming more ubiquitous the processes of refining its use
and recovering the costs involved should, like electricity did once,
fall with the greater uptake. Perhaps the union of AI and quantum
computing will provide the impetus for a dramatic renaissance and
dynamism to the sciences and technology.

Boffins have been debating whether the fictional devices of the TV
“Star Trek” series such as matter transporters can not only be
imagined but also constructed and used. Perhaps we are at the dawning
of the Age of Aquarius after all and amateur radio will see a
flowering that few of us can imagine.

I’m Geoff Emery VK4ZPP and that’s what I think….how about you?
