This is Allan VK4HIT with news from Ipswich and District Radio Club.

Just a reminder for members who expressed an interest in learning how to
set up and operate the WICEN portable repeater, that Saturday morning
April 22, at 0900Hrs has been set aside for this event. Bob VK4EK will
show how it is all done so that for future events members can start to
take some of the burden off Bob and Sylvia and thus not having to rely on
them 100 per cent.

Please attend if you can and contact Robert VK4KHW or Greg VK4GJW beforehand.

And a reminder Ipswich Wicen is always on the lookout for extra help for
these events, so if you can, please email ipswichwicen@...

Here’s an item to note on your calendar:

On Monday night May 8 at 1930Hrs, the club will have the pleasure of a
presentation by Scott Watson VK4CZ and Dr Kevin Johnston VK4UH on An
Introduction to Amateur Microwave Activity in SE VK4.

It promises to be a very interesting presentation, helping to dispel a lot
of myths around operating on the microwave bands. Why not roll up and join
in the conversation.


Reporting from Ipswich this is Allan, VK4HIT.

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


It is one of the truisms of life that if you are taught how to handle
things that
some consider dangerous and you are taught properly, you will use the
appropriate
caution and methods throughout your life. Whether it is the correct use of
power
tools, firearms, farm chemicals or electricity, to give a few examples,
the lessons
that were well given remain as guardians of our health and safety
throughout our
lives.

My early experiences with building radio gear was when basically batteries
were
beyond the pocket money of a school student and most appliances were mains
powered.
This meant that there was a plentiful source of second hand parts to be
sourced and
put to use by the home experimenter. Learning safety around mains voltages
was
greatly aided by the construction articles of the time in publications
such as
Radio, Television and Hobbies, commonly known as RTV & H, which morphed into
Electronics Australia. Then there were the opportunities to learn from
people who
worked in the electrical and electronics industries and who volunteered in
local
groups.

As an aside, two of the editors of 20th century electronics magazines in
Australia
were Max Hull and John Moyle and last weekend saw a large participation in
the John
Moyle Field Day. If the pictures that I have seen posted of this year’s
activities
are an indication it was well enjoyed. Perhaps it has even spurred some audio
reports for the weekly news broadcasts. Hint, hint.

Now in the 21st century we are involved with solid state circuitry and the
need for
home construction of power supplies using mains power is often negated by
the prices
that we can buy manufactured units of the shelf. This is perhaps a step on
the road
to greater safety.

One area where technology has been evolving is that of electricity storage
with many
new combinations of electrode materials coming into battery production.
The current
front runner for many applications where high current draw is required is the
lithium ion device. We will all have heard of the difficulty that the fire
fighters
have in dealing with the fires when things go wrong with lithium ion
batteries.
Houses being burned down because fires were started by charging e-scooters
within
the premises. Children sustaining burns from connecting phones to chargers
and then
covering them with bedding and of course we must mention the electric
vehicles named
after the father of much of our electric and electronic engineering, the
Tesla.
These are notorious for the length of time they can combust after incidents
effecting the batteries.

The ACCC has published a paper looking for solutions to issues around the
lithium-ion technology in the search for greater safety in their use. This
past week
saw a press release from the University of NSW Newsroom (UNSW Newsroom
20/3/23, Neil
Martin) which discusses many of these issues and offers some basic advice on
improving the safety and use of these batteries. There will be many clubs
with tools
powered by these batteries and a fair number of shacks will likewise have
drills and
similar providing light weight and convenience. I don’t even want to think
of the
number of tradies with these in their tool boxes!

I suggest we all chase out this paper and pay attention to it’s early advice.


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