Keyboard - August 2003.
The Sun is
the dynamo of life on this planet Earth. Even as early as 200 BC
the Chinese were studying its movements and effects on life here
noting the sunspot activity visible on its surface. It was Galileo
in 1611 AD using the newly invented telescope who reported the Sun
was a dynamic evolving body. Being some 150,000,000 Kms from the
earth and with a radius of 696,000 Kms. Its emissions light our
days and supply our warmth its sunspots and magnetic storms both
enhance and interrupt our worlds communications. As with most other
bodies in the solar system the Sun rotates but this is not uniform
over its surface.
At its equator the rotation
is once every 27 days, but near the poles it takes 31 days. You
are probably asking why on earth I am bringing this info to your
notice. The reason being that at the class exams on Monday last
I am told one question asked for the rotation time of the sun, I
hope the answer sheet takes into account the variation that occurs.
I am left wondering whether the students were sitting for an exam
in radio or perhaps astronomy.
The Hamfest. I am
pleased to report that the day was both enjoyable and profitable
in all respects. Canvassing both sellers and buyers the comments
I heard were positive. I would like to thank all who lent a hand
on the day for a good effort. We were fortunate to have a hard working
sub committee the fruits of whose efforts are clear to see in the
way things happened on the day. Therefore our sincere thanks to
Albert VK3BQO, Keith VK3VKS, Graham VK3KCS, & Ian VK3KSZ, well
organized guys Friday the 1st Aug we joined in a good
bye party for Keith VK3VKS and XYL Shirley, by the time you read
this they should be ensconced in a new home in Darwin. Keith has
promised to keep in touch via IRLP so keep a ear out on VK3RLP.
We wish them every success in their move.
All our upcoming
activities are in the event queue so keep up to date. Some things
to note Mr Michael Owen VK3KI a WIA rep to the recent ITU conference
will be speaker at our October meeting, one not to miss. We still
need input for Australia/Labour/Easter activiteis.Well that’s enough
from me CU on Air ???

IRLP
Ideas
Monitoring the VK-IRLP users email group has turned up some
ideas for IRLP usage, like putting club nets, WIA division broadcasts,
etc up on irlp reflectors for all to listen to.
---------------------------------------------
Hi All
Anyone ever mentioned this one before...........?
I reckon a few more of the Clubs around Oz with nets on repeaters
that have
IRLP connectivity, could do themselves a favour and connect to a
reflector
sub channel for theirs. Good promotion for their Club and area,
and from
what I gather most of the reflector owners would be stoked to get
some
activity on their machines. Good stuff for the listeners too.
..... John VK2BUI
-----------------------------------------------------
Or how
about something more visual ?
-----------------------------------------------------
FYI - Our Club has
a SSTV Net on Monday's from 1930 - 2100+ on our linked
Rptr system.
There is a co-ordinator & everyone sends one picture at a time....it's
good fun.
Is this the sort of thing we'd chuck on a reflector sub-channel?....
Rob - VK2MT
6010
-----------------------------------------------------
Hi All,
Our linked VHF Rptrs (affectionately called "Coastlink") which are
across our Node relay the VK2 Broadcast on Sunday mornings &
evening.
(This is via the Dural link using automatic relaying with CTCSS.)
It
would be a simple matter to connect to a Ref Sub Chl at 0945 &
1915 to
send out the relay to IRLP world. (What wouldn't be simple would
be
for me to remember every week though!.....)
-----------------------------------------------------
If club members are interested,
a minor change can be made to our IRLP box so these broadcasts etc
can be run thru VK3RLP for all to listen to - a kind of replacement
for the long gone MDRC broadcasts, so interesed members can keep
up with what is going on around this country.

Will Rogers
Will Rogers, who died in a plane crash with Wylie Post in
1935, was probably the greatest political sage the United States
has ever known. Enjoy the following quotes----
1. Never slap a man who's chewing tobacco.
2. Never kick a cow chip on a hot day.
3. There are 2 theories to arguing with a woman...neither
works.
4. Never miss a good chance to shut up.
5. Always drink upstream from the herd.
6. If you find yourself in a hole, stop digging.
7. The quickest way to double your money is to fold it and
put it back in
your pocket.
8. There are three kinds of men; The ones that learn by reading.
The few
who learn by observation. The rest of them have to pee
on the electric fence.
9. Good judgment comes from experience, and a lot of that
comes from bad
judgment.
10. If you're ridin' ahead of the herd, take a look back every
now and then
to make sure it's still there.
11. Lettin' the cat out of the bag is a whole lot easier'n
puttin' it back.
12. AND FINALLY: After eating an entire bull, a mountain lion
felt so good
he started roaring. He kept it up until a hunter came along
and shot him...
The moral When you're full of bull, keep your mouth
shut.

About Growing Older
First, Eventually you will reach a point when you stop lying
about your age
and start bragging about it.
Second, The older we get, the fewer things seem worth waiting
in line for.
Third, Some people try to turn back their odometers. Not me,
I want people
to know "why" I look this way. I've traveled a long way and
some of the roads weren't paved.
Fourth, When you are dissatisfied and would like to go back
to youth, think
of Algebra.
Fifth, I don't know how I got over the hill without getting
to the top.
Sixth, One of the many things no one tells you about aging is
that it is
such a nice change from being young.
Seventh, One must wait until evening to see how splendid the
day has been.
Eighth, Being young is beautiful, but being old is comfortable.
Ninth, Long ago when men cursed and beat the ground with sticks,
it was
called witchcraft. Today it's called golf.
And finally, If you don't learn to laugh at trouble, you won't
have anything
to laugh at when you are old.

Beer
Hormones
Courtesy VKIRLP
users group email.
Gentleman, something
to be concerned about. See Report below.....
Yesterday, CSIRO scientists released results that suggested that
men should take a look at their beer consumption, considering the
results of a recent analysis that revealed the presence of female
hormones in beer. The theory is that drinking beer makes men turn
into women.
To test the finding, 100 men were fed 6 pints of beer each. It was
then observed that 100% of the men gained weight, talked excessively
without making sense, became
overly emotional, couldn't drive, failed to think rationally, argued
over nothing and refused to apologize when wrong.
No further testing is planned............

Fratelli’s restaraunt
This time it
was my turn to pick a place to go out to, Me and the misses have
been to this place several times in the past, so I thought it would
make a slight change of pace to the pubs nights. We had found their
prices quite acceptable in the past, almost half those of a ‘Lone
Star’ steak house, also in Frankston that has now gone bust - I
wonder why? (pity, they were a good eat)
When we arrived, we had
a little disagreement with the manager, it looks like he had stretched
his resources a little, and there was another party of 30 coming
in at 8:00 and he had a fond hope that we would be done by then,
exit early saving his bacon.
Normally they can seat
people in an outside eating area, however in the middle of winter
on a wet night that just was not going to happen, anyway they soon
had things sorted and that was the end of that.
(However it did make
for some colourful Italian from Marianna )
I had the fisherman’s
basket, one of the more expensive meals on offer, of course someone
had to make the comment that it could not be the fisherman’s basket,
because it was not in a basket - talk about fussy!
As usual, to keep up
my image as a pain with the camera, I took the odd picture - I wouldn’t
want to disappoint anyone now would I. Anyway, if you would like
a look, point your web browser to -
http://www.users.bigpond.com/pastubbs/Fratelli/default.htm
Failing that, they will
end up at the club on a CD, just ask - especially if you are after
an image to get a print from.
No PC or printer, no
problem, just take the CD to a camera shop (Teds, etc) and they
will print a selection for you on proper photo paper (not inkjet
paper), mind you, at $1 they ought to be good.
It has been suggested
that we go back to the Cardinia hotel for a future pub night (where
we held the 25th year celebrations) for a future event
- Peter? suggested we give it a go when the warmer months come about.
If you have any suggestions,
don’t hold back, put your hand up at the next meeting.

GGREC IRLP/70cm Repeater Project
John VK3XJW
This month I will
be finishing off the controller that I designed for the repeater,
before it is installed in the cabinet. This controller will provide
the repeater with some interesting features not normally provided
by the standard repeater controller.
Most repeater controllers
just provide CW ident and timing for PTT timeout. To change the
time between idents or the PTT timeout length, the controller IC
has to be re-programmed. This means travelling to the repeater site,
with a laptop computer and IC programmer, removing the controller
IC and reprogramming it. So you could say goodbye to a good part
of a day depending on how much travelling you have to do.
With this repeater controller
I can change all of its functions locally at the site, by selecting
the functions with the three buttons on the front of the repeater
or remotely from my QTH via the IRLP radio link. By running a small
software program on my computer, which is connected to the IRLP
link radio, I can change the following function on the repeater
remotely. Ident time, PTT timeout length, Cooling fan on temperature,
Cooling fan off temperature, CTCSS encode enable/disable, CTCSS
decode enable/disable, VSWR alarm level, battery low alarm level
and DTMF signal strength meter enable/disable.
Some
other interesting features of the repeater are DTMF signal strength
meter and voice ident. By sending DTMF ‘20’ to the repeater, a pre-recorded
voice will return a signal strength reading in ‘S’ points of your
signal to the repeater. There is also a pre-recorded voice ident.
(Note these features are disabled until the controller is completed).
The antennas for
the repeater and beacons are ready to be mounted on the mast that
will be assembled at my QTH before installation at the repeater
site in a few weeks.
Well that’s it for now.

Goodbye bar codes
There could be some very
invasive uses of these techniques if merchants use the tracking
technology to spy on their customers after purchase.
-- Marc Rotenberg, Electronic
Privacy Information Center
WASHINGTON (AP) -- Razor
blades and medicines packaged with pinpoint-sized computer chips
and tiny antennae to send retailers and manufacturers a wealth of
information about the products -- and those who buy them -- will
start appearing in grocery stores and pharmacies this year.
Within two decades, the
minuscule transmitters are expected to replace the familiar product
bar codes, and retailers are already envisioning the conveniences
the new technology, called "radio frequency identification," will
bring -- even as others are raising privacy concerns.
Expired milk reported
A grocery store clerk
will know immediately when the milk on the shelf has expired, for
example, and replace it before a customer can choose it. Stores
could quickly pull from the shelves tainted and damaged products
that are recalled or have expired, especially important in health
care items.
"It would help you manage
your inventory a lot better," says Todd Andrews, spokesman for the
Rhode Island-based CVS pharmacy chain that will soon test the chips
and antennae on its prescription medicines.
CVS's 4,000 stores fill
millions of prescriptions each year but many customers forget to
pick them up.
"If you could utilize
RFID technology to tell you that a prescription is in the waiting
bin, maybe the product could say: 'I've been here 10 days and I
haven't been picked up yet.' Then, you could call the patient,"
Andrews says.
The technology builds
upon the UPC (Uniform Product Code) symbol and bar codes that, when
read by a scanner, enable manufacturers and retailers to keep up
with their prices and inventories. A computer chip smaller than
the head of an ant and a thin antenna attached to a bottle, box,
can or package will alert retailers and suppliers when a product
is taken off a store shelf or moved out of a warehouse. A radio
signal is beamed to an electronic reader, which then delivers a
message to a computer in the store or factory.
Retailers fund research
CVS, Procter & Gamble
and The Gillette Co. are among the 100 retailers and manufacturers
that have put up a total of $15 million for research on the new
tags at the Auto-ID Center at the Massachusetts Institute of Technology.
Other Auto-ID labs at the University of Cambridge in England, Adelaide
University in Australia, Keio University in Japan and USG-ETH in
Switzerland are also working on the technology.
Radio frequency identification
technology is not new. The tiny chips and small antennae already
are familiar to workers equipped with security cards that, when
waived in front of a receiver, unlock the doors to their offices
or relay information about the bearer to a guard.
The technology's potential
for sending retailers and others information about consumers is
already raising privacy concerns, however.
Potential for spying
Marc Rotenberg, executive
director of a watchdog organization, the Electronic Privacy Information
Center, said retailers should be required to disable the tags before
a consumer leaves a store.
"Simply stated, I don't
think most people want their clothes spying on them," Rotenberg
said.
Researchers developing
RFID tags for products so far have focused on the supply chain and
limited the range at which a product could be detected. Once their
use becomes universal the cost of the tags could be as little as
a nickel each, they say.
Sanjay Sarma, the lead
researcher at the Auto-ID Center in Massachusetts, says that by
adding more functions to the chip, installing a battery and attaching
a longer antenna, a receiver far away could read all the information
on a chip, including its exact location.
Alerting consumers, marketers
Homes equipped with receiver-readers
could alert consumers when they are running low on orange juice
or their prescription for heart medicine is about to expire. Hooked
up to a national network like the Internet, the at-home devices
could also provide details to marketers about a family's eating
and hygienic habits.
Sarma acknowledges that
gigantic privacy concerns the technology raises, saying one way
to address them would be letting consumers disable the chips once
they leave a checkout counter.
"Any technology can be
abused and we've got to be prepared, be watchful for the abuse,"
Sarma said.
Ron Margulis, a spokesman
for the National Grocers Association, said the privacy concerns
are far outweighed by the benefits of RFID. Retailers, he said,
could respond much more quickly to product recalls and prevent people
from becoming ill from tainted products.
"You do give up a bit
of privacy but the benefit could be that you live," said Margulis.

2003 Hamfest
It looks like our Hamfest has been well received with several
stall holders wanting to come back next year. It kind of reminded
me of the Ballarat hamfest
My day started with the
mad packing of the car, it was a pity I could not start setting
up my table the night before as was done in the guide hall. Oh well
better pack the car well as I was planning to bring the other half
with me so that I could escape from my table and have a wander around
and see what was happening.
Thing started out bad
when I arrived with Peter asking me for money to pay for Marianna’s
attendance, I thought he was joking, so I gave him the heave ho!
Five foot inside the
hall and Marianna was grabbed by the kitchen crew, dressed up like
a chef and put to work, so much for my stall assistant. I will have
to make do with a quick look around before the general public is
allowed in. Unfortunately some of the items on my table were not
mine, and were valued at over $100, if one of these should walk,
there goes my days takings. So any moves away from the table to
take photo’s etc were limited to viewing distances of my table.
It was a pity that I could not get up on the stage to grab a photo
or two of the various prizes being presented, however I did notice
Ian was up there with his camera snapping away. The bloke on the
next table to me saw my efforts and was quick to give me his email
address so I could send his pictures to him.
As I did with my previous
photo’s, I have put them up on my ISP’s web site as a web page for
club members (and others) to view, just point your browser to
http://www.users.bigpond.com/pastubbs/2003_hamfest/default.htm
One buyer bought a video
camera from me, however after paying, he unscrewed the lens then
dropped the leftovers back on the table and walked! Unfortunately
I was unable to sell the leftovers - after all, what is the use
of a camera with no lens, even if the price is only $1 (going for
a ‘double’ sale was a bit ‘greedy’)
At the end of the day
my wallet was somewhat thicker, so I must have had some success
for my efforts. (Marianna liked the extra room in the car)
My major achievement
was moving a Sun workstation complete with 19inch mono monitor and
external hard drives for $50, hope they enjoy it.
Unfortunately, the next
day I discovered I had forgotten two largish plastic boxes of goodies,
oh well. - maybe I should get a towbar and trailer for next year.
