New
Years Presidential Notes
I being this
new year as I finished the old one hoping that all club members
and families had a safe happy and peaceful Christmastide and indications
of a great year to follow. 2003 already, what does it hold for us
as individuals and as radio club members? The answer is beyond my
crystal ball but I am sure that our attitude to the situations we
find ourselves in and wise reaction as a response will see us greet
the end of this year with satisfaction.
It is always great to
see new call signs within the club families and especially when
it’s a young person so I am sure you all join with me in congratulating
Ross Jackson in gaining his limited novice ticket at the first attempt.
Look for him on the air as VK3HDW. Good on you Ross, watch out you
mature novices Ross intends to upgrade very soon.
You will find the 2003
Event Queue in the centre of the magazine, our editor places it
there so it is easy for you to detach and affix on the fridge where
all the family can keep track of events.
A few events need special
mention. Australia Day weekend this year is situated in the Neerim
Sth/Ji9nkdivik area, this is less than an hours drive for most members
and we hope that those of you that cannot make the whole weekend
will consider joining in the events on one day or another. Those
who would like to be with us for the meal on the Saturday evening
please let Ian Jackson know soon.
The March Labour Day
weekend trip is to Hayfield/Sale, at the moment I only have two
families registered. Although we are staying at a Sale caravan park
the intention is to spend Saturday at the machinery rally at Hayfield
and then Sunday in the Gippsland Lakes National Park and perhaps
Seaspray for a swim depending on the wx. If the idea appeals please
register at the next club meeting.
March will also see the
start of the radio classes being headed up by Ian, if you know of
any one who is interested in joining these study sessions please
put them in touch with Ian soon. Start date is March 17th.
I know April seems a
long way away now but because Easter falls on the third weekend
this year we will have to shift our AGM to a different date than
would be normal.
So mark your diaries now the AGM of GGREC this year will take place
at the clubrooms on Friday April 11th commencing at 8pm.
And as that ad on tv says, Be There.
It seems there may be
some interest in another trip to the Flinders Ranges. The most likely
time for this would be in the September School Holidays. (19th
Sept – 6th Oct).
Last time we had a ball, any queries or ideas speak to one of the
committee. We will need firm interest by June / July.
I look forward to meeting
you all as the year and the activities unfold.

Stupid
Amateur Tricks 101
Randy
McLain KD5NZH (From the internet)
I hate to tell
off on myself but they say that confession is good for the soul.
I have been ham for only about 2 years now but I have already pulled
some really stupid tricks. Following are just a few I'm willing
to share...
- Cross band tricks
I have an Icom 2800 rig in my truck. As you well know this radio
is capable of monitoring 2 bands at the same time.
On several occasions I have answered a call on the wrong band
and after repeating my call several times with no answer I actually
stopped the truck to check my antenna.
- The old sit on
the mike trick Once during a Skywarn net I rushed out to my
truck to turn on the radio after getting a signal from my pager.
The LED meter showed full strength on the Skywarn repeater frequency
but there was no audio! What could be wrong?
I stared dumbly at the radio and turned the volume knob up and
down (at this point I think my face probably resembled that of
a dear just seconds before a truck runs him down).
Then inspiration hit as I noticed the red transmit light glowing
on the face of my rig. I frantically searched for the mike. Yep,
right where my brain was...
- The old lost power
trick After I passed my General exam I purchased a new HF
rig. One night I rushed into the shack eager to get on the air.
Anticipation was high as I booted the computer to get my logging
program up and running. The sunspot numbers were through the roof
and I knew that I was bound to make many new contacts.
I confidently reached up and stabbed the power button on my rig.
Nothing happened! WHAT! What could be wrong? It worked great last
night! My heart sank, my rig is dead!
I imagined the long wait as the radio was shipped to the far away
repair shop and the hours of precious radio time I would lose.
But wait, it could be a fuse! I checked the in line fuses. They
were fine. Maybe an internal fuse? I carefully unhooked all my
station gear, removed all the covers from the radio, and peered
inside the radio.
As I was doing this a nagging thought occurred, did I check the
power supply? Well? A quick glance to my right revealed the power
supply dumbly sitting on the desk waiting for some idiot to turn
its power switch on.
Epilogue: Not listed
but guilty all the same... How I learned about working split. Which
end of a solder iron gets real hot.
Mobile antennas don't like tree limbs (antenna base Ht. = 5' Tree
Limb = 5') How I learned how much feed line to leave loose so rotor
can turn antennas full 360 degrees.
While this list is representative of my indiscretions it certainly
is not exhaustive. But it has only been 2 years!
I'll check back after
10.

The
hot new technology at the Consumer Electronics Show (USA) this year
is--FM radio?
Yup, the humble
broadcasting technology, which ceased being a novelty around the
time of Woodstock, has re-emerged in several new and potentially
significant permutations.
Unused portions of the FM radio spectrum are Microsoft's transmission
medium of choice for Smart Personal Objects Technology (SPOT), the
pervasive-data concept the software giant is showing off in the
form of gee-whiz wristwatches.
SPOT watches, to begin appearing on store shelves late this year
from manufacturers such as Fossil and Citizen, will download sports
scores, weather reports and other simple data types selected by
the consumer.
Data will be beamed by service providers, who will lease carrier
capacity from existing FM broadcasters, and watches will automatically
retrieve the signals using FM chips built into the watches.
Microsoft is calling the technology DirectBand. Roger Gulrajani,
Microsoft's director of marketing for SPOT, said the software giant
looked at a number of wireless technologies before settling on FM.
"It was really a matter of size and battery life," he said. "When
we looked at Wi-Fi, there was just no way we could fit that into
a watch...The FM spectrum turned out to be this great, underutilized
asset."
FM has the advantage of using infrastructure that's already built
and can easily handle the type of tiny, continuous data downloads
DirectBand will require.
Instead of retrieving information on demand, SPOT devices will automatically
download updated data so that fresh weather reports or news updates
are displayed with one click.
"The bandwidth is pretty
transparent," Gulrajni said. "To the user, it's blazingly fast,
because the weather report is right there when they want to look
at it." A few issues remain to be worked out, such as exactly who
will pay for and provide services using the DirectBand network that
Microsoft is building.
Makers of SPOT devices may provide their own proprietary services,
and Microsoft might offer DirectBand services through its MSN Internet.
Costs to the consumer are expected to be minimal.
Brian Halla, CEO of National Semiconductor, the chipmaker working
with Microsoft to create the components for SPOT devices, says the
costs for components and services are low enough that watches and
other SPOT items will become impulse buys in a few years. "The watches
will be shrink-wrapped in 7-Eleven next to the Altoids, and people
will get them for $20 with service," he said.
National is working on
designs for several other SPOT devices, including a DirectBand receiver
that would fit into the SecureDigital memory slot on handheld computers.
"FM is a great way to go for this kind of connectivity," Halla said.
"You get much better access, and most of the network is already
there." FM radio was also big news in the automotive pavilion at
CES, where Ibiquity Digital was showing off the first car and home
receivers to tap into the digital FM spectrum the company is powering.
Radio stations will be able to broadcast digital signals starting
this year, using Ibiquity-developed technology that recently received
FCC approval, much as television broadcasters have slowly begun
offering digital HDTV broadcasts.
The difference is that
radio broadcasters will need to spend only about $80,000 for the
equipment needed to go digital, compared with the millions a TV
station must spend to switch. As a result, Ibiquity CEO Robert Struble
expects much faster pickup for digital radio, which offers CD-quality
sound and room for a host of ancillary services, such as readouts
that offer detailed info on what you are listening to and options
for buying CDs by the artist.
"Broadcasters are really picking up on this, because it's a small
investment, and there's a real payoff," Struble said. "The biggest
challenge for radio is the growing number of distractions people
have--CDs, cell phones, all sorts of digital devices for the car--and
this gives people more reasons to pay attention to radio."
Ibiquity, which licenses technology to makers of broadcast and receiver
equipment, expects that the 300 stations covering two-thirds of
the United States will be broadcasting in digital by the end of
this year.
The first digital radio car receivers will go on sale in the second
quarter of this year, with home units to follow.

GGREC
IRLP/70cm Repeater Project
The GGREC
IRLP is on the air! We are only running simplex 439.475MHz
at this stage as the repeater is still under construction. Our node
number is 6794 and will be on the node list very soon.
Many thanks go to Peter VK2XY for setting up the IRLP software for
us. Having set up some 200 IRLP nodes I think he knows what he is
doing. Also we have received our call sign VK3RLP for the
repeater.
Ian VK3BUF and myself
will start on the repeater cabinet later this month and hope to
have it completed by early february. Installation of the cabinet
at the water tower should be completed by mid february, with the
power connection and repeater installed by the end of that month.
I require some Philips FM828 U band parts for the repeater to convert
it to 435MHz. The PA driver module MHW710-2 and the RX front end
filter. Anyone who knows where I can get the bits please give me
a call on 439.475MHz or 144.600MHz.
The IRLP computer
has been installed into a 19" rack mount case (see below).
With a bit of a push and shove, I was able to get all of the computer
to fit inside a Jaycar 3U rack mount case.
I used the back plane off the old computer case to make the mounting
of the PC cards easier. After taking about an hour to cut out one
of the large holes in the back panel and 6 more to go, I thought
there has to be a easier way to do this. Off to the hardware store.
In the power tool section, I finaly got one of the shop assistants
to understand what I was wanting to do, he said "Scroll saw".
He walked me over to the most expensive one on display (as they
do), with a $1000+ price tag.
After 5 minutes of why I should buy this unit, I pointed to the
Scroll saw up the far end of the display and asked will that one
do the job. After another 5 minutes as to why I should buy the $1000+
and not the $99 one, I bought the $99 scroll saw.
I could justify spending $99 on a power tool that I will only use
maybe 5 times a year, but not one over $1000. After getting it home,
45 minutes later I had all 6 remaining holes cut out. I should have
got one these years ago!
I made up a front label,
put it all together and it looks great! (Top- Completed with top
cover removed. Bottom left- top view with no drives. Mid right-
rear panel of computer. Bottom right- front panel with label attached
before installation.)

the Directions, Stupid!
Jim K5JDB ( From the Internet)
Last November, I proudly unpacked my beautiful new Cushcraft
MA5B antenna and carefully laid it all out, checking that all the
parts were included . . . they were.
I assembled it carefully
and anxiously awaited the weekend when I could place it atop my
30 foot push up pole. In the meantime, I purchased a rotor from
Radio Shack so that I could finally become a true DXer.
Short of having an amplifier, I moved up two notches (in my mind)
in the world of ham radio. Well, I put the antenna up and immediately
I noticed the difference in my ability to hear and contact stations.

Alas, after a couple
of months, I decided to be sure that the connections were all still
tight and so I lowered it to check. Oddly enough, I noticed that
a couple of the traps were not facing the same direction.
Well, (easy enough) I turned them around and raised the MA5B back
to its glorious height of 30 feet. I did not have opportunity to
get on the radio for almost two weeks after that and when I did,
my Kenwood TS-570dg began to have a noticeably more difficult time
of tuning the antenna.
I borrowed an antenna
analyzer from a fellow ham and found that the swr was above 10 to
1 on all bands except a part of 17 meters. I then contacted Cushcraft
and after several conversations with Ed
Hammond , he sent me a new matching network. I wearily installed
it and lo and behold, no change.
After climbing down from
the roof for the 50th time, I retired to consult the MA5B assembly
booklet ONE MORE time. What?! The traps are supposed to have the
arrows pointing OUT???!!! Shazam! I didn't know what difference
that would make, but at this point, I would have tried anything.
I
reversed all the traps and the swr is now below 2:1 on all five
bands. The TS-570 tunes all bands easily and am I pleased.
All of this could have been averted if I had just read the instructions
more carefully. But, I did get a needed lesson.
Thanks to several of my fellow hams, K5GQ, N1LN, WA5MLT who daily
gave me encouragement and especially Ed Hammond with Cushcraft who
took the time to help me.

2.4GHz
STEREO AUDIO VIDEO TRANSMITTER / RECEIVER KIT

This kit contains K171C
& K171D modules and includes PCBs and all on-board components
(10mW Maximum legal power).
These PCB's house voltage regulators and RCA connectors on the receiver
only. We are looking at doing a bulk buy on 2.4 Ghz transmitter
and receiver kits.
Currently the kits are priced at $99.00 but we hope to get a bulk
discount if enough people are interested. So far we have 8 people
interested in the buy up.
We will be making up antennas and power amplifiers down the track,
(most likely as a club project) Peter VK3KCG -Email VK3KCG@AMSAT.ORG
