Ipswich / Brisbane operation on 135.75 KHz
Approval has been confirmed by
A.C.M.A. for operation of an Ipswich / Brisbane
operation on 135.75 KHz under a Scientific Licence, this licence held on
behalf of the Brisbane Amateur Radio Club.
Transmissions and possibly a beacon will be established by Kevin VK4WA using
the callsign AX 2 QJM and will transmit from Redbank Plains.
And yes that IS a figure TWO, AX 2 QJM.
Interestingly Redbank Plains, an Ipswich suburb, is also the site for a
proposed Weather Bureau Radar installation.

Digital Radio Announces New
REAL TIME TRAFFIC SOLUTIONS OVER YOUR RADIO
Commercial Radio Australia has entered into an agreement with Sentinel
Content, (whose investors include the NRMA and RACQ), for the development of
real time traffic solutions via digital radio.
Rather than receiving an audio-only bulletin about a problem, the system
will deliver timely traffic bulletins and answers to the best alternate
routes to the destination. The service will be available on free-to-air
digital radio and using DAB+ will also be able to provide additional updates
for in-car and portable navigation systems.
Extra data such as parking information, fuel pricing and transit lane
restrictions could also be integrated into the system.
Free-to-air digital radio services will begin in Sydney, Melbourne, Brisbane,
Adelaide, Perth and Hobart from January 2009.

WAP MEETS HAM
Suitably designed Web-sites are usually required to allow
mobile phones with their small screens to be viewed properly.
These are called WAP-sites. WAP or 'Wireless Application
Protocol' is the protocol used to send and receive certain
data over mobile or cellphone networks.
Remember that one will not pay for the time connected,
but for the amount of data sent or received.
But what could be interesting enough to view to do that sort of exercise?
Well ZS6RO has designed a WAP-site so anyone can visit from
about anywhere in the world. The WAP Home-Page menu links
the cellphone user to various pages.
It has been running successfully for more than a year.
One link called 'DX-SPOTS' will bring back a screen with the latest
five DX-Spots from the International DX-Cluster network.
Another link called 'DX-Callbook' will allow the user to enter a
callsign, local or DX, and get a screen showing that callsign's
information. Think of the possibilities when you are on your next
field-day trip with your radio gear and mobilephone.
To access ZS6RO'sP site from a WAP-enabled cellphone, use the URL
www.zs6ro.co.za if that isn't successful, add to the URL /index.wml
The reason you may have to add to the URL is because some cellphone
micro-browsers are not always recognised correctly by WAP sites.
As a matter of interest, if one uses the same URL, without
the add-on just mentioned, on a standard desktop PC, the user will
be directed to the normal WebPage on the Internet which contains
other ham-related information.
Some desktop PC browsers may fail when trying to connect to a WAP site.
The reason is that the PC browser expects html content whereas a WAP-site
sends text content and this may 'confuse' the standard WEB browser.

HF marine weather service extended
Boat users along the Australian Coastline and High Seas will continue
to have access to the marine weather services through a High Frequency
radio service now that the Bureau of Meteorology has extended its service
to at least 2010.
"The Bureau provides mariners with continuous broadcasts of coastal
weather observations as well as coastal and ocean weather forecasts
Parliamentary Secretary to the Minister for the Environment and Heritage,
Greg Hunt says the Bureau's HF Broadcasts of Marine products allow the
delivery of information central to maritime safety and provides assurances
to mariners operating far from home base.
Mr Hunt says the service is especially important for smaller craft where
coastal radio coverage may be sparse or where long ocean voyages are
The Bureau has renewed the contract through until 2010 for the continuation
of the service, ensuring mariners would continue to receive maritime safety
information for the coming years.
Mr Hunt also stressed that the Bureau would be evaluating the needs of the
maritime user communities for continuing HF radio information services
beyond 2010, later this decade.
ACMA changes conditions on the

* increase the maximum EIRP to 100mW for wireless microphones in the 520-820 MHz band;
* authorise RLANs in the 5470-5600 and 5650-5725 MHz bands; and
* reduce the minimum number of hop channels for wideband frequency hopping spread
spectrum devices in the 915-928MHz band.

Many radio broadcasters are making their content available on the
Internet as a live stream. The actual number of listeners who can
be reached using this stream is limited since, by and large, the
Internet is a point-to-point channel.
Presently, the two dominant configurations for Internet streams are
unicasting where each listener requires an individual connection to the
broadcaster's stream server, and multicasting which makes better use of
the broadcaster's server bandwidth but requires the presence of multicast
servers distributed throughout the Internet.
Now a new concept in Internet streaming has been developed by a Danish
company www.octoshape.com and it's called Gridcasting.
This is modelled after the popular peer-to-peer (P2P) file sharing networks
such as BitTorrent.
Here's how it works:
The audio (or video) stream is broken down into a large number of
(lower rate) data streams such that none of the data streams are
identical. For example, a 400 kbps video stream is broken down
into twelve (different) 100 kbps data streams;
These streams propagate among the various clients that are signed on to
watch (or listen to) the stream. Each client needs to be running the
As these signals move among clients, information about who is
signed on is sent as metadata along with the data streams;
As long as a client is receiving any four (in this example) of the
12 different data streams, these four streams can be used to
reconstruct the original live stream.
Since all users continually monitor connections involving themselves,
bottleneck and congestion problems on the Internet are avoided.

limits are a licence requirement in Australia
The operation of all amateur stations in Australia requires compliance with
Electromagnetic Radiation (EMR) controls which limit the public's exposure
to radio frequency radiation.
The EMR controls also apply to other radio transmitters and mobile phones
that operate between 3kHz and 300GHz.
Last year the Australian Communications Authority carried out the first of its
annual audits of randomly selected apparatus licensees including amateur stations.
These audits require licensees to attest, in writing, that their station is

Power Supply Hazard Warning
John VK3ZRX has reported to his local
QNEWS Coordinator the following tale which has a very important message for all
During a very `colourful' incident at the QTH a near disaster occurred.
While it did not threaten either life or property as he was present at the time he has prepared a warning for other hams.
The shack suddenly filled with copious black smoke which stopped after shutting every thing down. The challenge was then to determine the source and to clear the smell out of the shack.
By `nose' elimination the faulty piece of equipment was located by the characteristic smell. After the unit was dismantled the offending device was identified. A rather large black mark was clearly visible on the printed circuit board - in the vicinity of the mains supply entry.
Culprit: -Capacitor - brand: - AEE - 'Miniprint'
Description: radial lead capacitor encapsulated in a clear or slightly amber coloured resin, with silver label inside resin.
Label has brand, type, and other info. The edge that is opposite side to leads is rounded.
Problem: Although rated for 250 VAC service, the capacitors are unreliable in this role. Typically the encapsulation splits, allowing moisture to enter the capacitor element leading to eventual catastrophic failure of the capacitor.
A few years ago there was a spate of domestic fires caused by 'MISTRAL' box fans - this type of capacitor was the culprit.
(Although not stated in the press, I am certain this is correct. I had one of these fans which failed with large amounts of black smoke.
One of the AEE caps in the thyristor-based motor speed control unit had failed.)
I have now seen several failures of this type capacitor and I have also found several unused ones in the junk box with cracked encapsulation.
Solution: Get rid of them!
If you have any in the junk box, a much better place for them is the bin.
I think these caps predated the 'X' and 'Y' mains rating system -
I have only ever found them in 'X' type applications (i.e. from line to neutral). If used as a 'Y' cap (i.e. line or neutral to ground) they would be especially hazardous.
Further Activity: - As most amateurs are inherently bower birds and plenty of older equipment can be found in many shacks it would be advisable that any equipment of Australian manufacture should be carefully inspected and any of the offending capacitors replaced with a more modern device.
Moral: - When purchasing older equipment bear in mind that while the unit is cheaper than a new one it bears the potential to become a `time bomb' that can cause havoc in the future -

AM MODULATION IMPROVEMENT
A new modulation technique for AM broadcasting is being touted
by industry pioneer Mike Dorrough in the United States.
Mike claims the Advanced Modulation System can increase carrier modulation to 200% while improving the performance, range and sound quality of AM radio.
He discussed the system at a recent meeting in Sacramento and plans other presentations. Ross du Clair, CE/DOE for Clear Channel in Sacramento, who attended the meeting, is quoted as saying, "This is real and it does work...." Read more:
How to sidestep EMI
Do you wonder about computers that are supposedly EMI compliant, but still put out heaps of RF interference? How do they do it and still comply with the regulations?
The answer was revealed on the VK-VHF mailing list . Many computer designers, who tend to design down to a price and don't care much about the interference consequences of their products, have resorted to some ingenious trickery to maintain compliance.
With a stable oscillator you get a hard line spectrum that may exceed EMC limits. However if you randomly frequency modulate the clock frequency you can reduce EMI readings by as much as 20 decibels. Total RF output remains high, but it's spread over a range of frequencies.
Thus the regulations are complied with, but the computer puts out as much interference as ever. As Chas VK3BRZ pithily wondered, do the design engineers concerned wash themselves properly, or just spread the dirt around thin enough that it's not so noticeable?!

NZ KIWISAT TO BE HAM RADIO
The planned New Zealand KiwiSAT ham radio satellite will also be a ham
radio environmental research bird as well.
Late word from AMSAT New Zealand is that the KiwiSAT ham radio
satellite will now carry an additional special beacon available for
use by radio amateurs around the world. This, to collect data on
atmospheric aberrations and to assist with information collection
directly associated with global warming concerns and carbon balance monitoring.
Details have yet to be finalized however the KiwiSAT structure has been
modified to incorporate a second 70cm monopole antenna and a high level of
filtering has been incorporated to minimize any desensitising of the on-board
70 centimetre receivers. Once in space, the beacon will be switched as
required but will normally be "on" for a given whole orbit to provide for data
Meantime, the KiwiSAT linear flight transponder is currently
transmitting from the Whangaparaoa area with beam antennas pointing
South. This transponder is inverting type to compensate for Doppler
shift when in orbit. Its transmit Power is 2 Watts PEP. Its uplink
is Uplink is from 435.265 to 435.235 MHz on lower sideband and the
downlink 145.850 to 145.880 MHz on upper sideband. The inverting
transponder is used to correct for Doppler shift.
Reporting from Auckland, I'm Jim Meachen, ZL2BHF, for the Amateur Radio Newsline.
KiwiSAT is currently planned for launch in mid to late 2009. Its
planners say that KiwiSAT is designed for low duty cycle modes and the
use of FM wile not outright banned will be discouraged. Further
information is on-line at www.kiwisat.org and we will have more ham
radio space related items later on in this weeks news.

Lasers for satellite communications
Scientists suggest laser technology to block possible bottleneck Several scientists are calling for the use of lasers to beam scientific data back to Earth instead of the usual radio waves, saying it will prevent an imminent communications bottleneck. Creating the potential problem are spacecraft planned in the next decade by NASA and other satellite users that will zap back at least 10 times the data sent now. That will create gridlock unless the satellite industry switches to a laser telemetry system. The move would cost hundreds of millions of dollars, but experts said the technology is well worth the investment. Using near-infrared lasers to communicate would essentially be like fibre optics without the fibre but the technology is still being developed.
(from a packet bull distributed by ZL2VAL)
Where else are LIPD's to be
The 70 centimetre band is not the only place where small transmitters such as so-called LIPD'S or "low interference potential devices" can be found.
An ACA brochure called "Spectrum Opportunities for Short-Range Radio-communications" lists many more.
You'd be amazed at the sorts of applications to which low powered transmitters have been put.
Possibly the most common examples are, Remote controlled car alarm systems and Garage door openers. These operate near 304, 345 and 433 MHz. Personal and Duress alarms, with medical and safety applications operate around similar frequencies as well as above 900 MHz.
Fancy some radio foxhunting? Well, animal tracking devices use 151 and 173.5 MHz. And if you're into tracking Whales and/or Sharks, you need to go down to the 48 to 49 MHz band for this.
What about locating lost joggers? Lost? We can only assume that they are - why else would anyone go round and round the same block a dozen times if they're not lost? No matter, 77.4 MHz is the place to be for athlete location systems.
What is termed "Auditory assistance" is found near 3 MHz, around 42 MHz, the FM broadcast band, and around 2.4 GHz.
These are generally the systems where people put on wireless headphones for spoken information at museum exhibits and the like. The 2.4 GHz segment is also shared with other applications, such as barcode readers.
Listening to cordless phones is illegal, yet Baby-monitors are not. You can find these around 35 MHz, although we have also heard them near 27 MHz.
Cordless phones, by the way, use a variety of frequencies, such as 1.7/40, 30/39, 915, 1900 and 2400 MHz. Cheap two way radios can be found near 27 MHz, with 55, 152 and 433 MHz also in use.
Radio controlled models use a variety of frequencies, such as 27, 29, 36, 41 and 433 MHz. And somewhat bigger models, trains to be exact, use frequencies near 900 MHz for tracking purposes.
Perhaps someone is bugging you? Well, listen for yourself by tuning around 39.5, 88 to 108, 174 to 230, 520 to 820 and 915 to 928 MHz. You'll hear a feedback howl in the receiver if your room is being monitored.
We already know about those pesky crane controllers near 433 MHz and an alternative frequency for them is near 472 MHz.
Keeping tabs on crims is easy if you tune to around 314.2 MHz, that's
the "Home detention" monitoring device frequency.
Have you ever thought about communicating with your bodily implants? No, well, apparently 262 kHz is the place to try for 'implantable medical
Biomedical telemetry however also uses various VHF and UHF frequencies including the 70cm LIPD band. We just hope no one is using a 70cm. hand-held in the vicinity!
Moving up, we see the Gigahertz segments used for applications such as distance and speed measurement, cruise control systems, radar fluid measurements and handheld data terminals.
But we've barely scratched the surface. We could go into e-tags, product security tags, computer networks, underground communications, wireless weather stations, video surveillance and more.
It's amazing what has a transmitter or receiver attached to them these days.
Interesting microwave frequencies
Is there really anything to hear above 1300 MHz? Murray
VK2KGM says yes, and has submitted the following item on the S-band, which is
between 2 and 4 GHz.
Some interesting S-Band (2-4 GHz) frequencies to watch are the News Helicopters - and other terrestrial links just above the Amateur Band (2.40 GHz to 2.45 GHz) in the broadcast link band.
Equipment needed includes an old Galaxy MDS grid dish and down converter (which has a Local Oscillator on about 1500 MHz or so), an old FM satellite TV receiver and a TV set. The sound is on a 7.0 MHz sub-carrier - you can set your satellite receiver for this. Many people who have disused Galaxy systems on their roofs are happy to give them to you for taking the trouble of getting them down.
Murray built a down-converter kit from Minikits, but found that many of the old down-converters also work OK.
The list of TV Outside Broadcast S-Band link frequencies Australia wide are:-
ABC - 2477 MHz & 2596 MHz
Seven Network - 2505 MHz & 2624 MHz
Nine Network - 2633 MHz & 2652 MHz
Ten Network - 2561 MHz & 2678 MHz
These are licensed for 20 Watts maximum input into their antennas.

adopting Linux is that there is often poor support for amateur radio programs.
One of the better attempts at providing amateur radio operators with a suite of
'free' programs for amateur radio is to be on the web
This variant on Knoppix comes complete on a single CD-ROM ... and is freely copyable onto your friend's disk, etc. Originally written for the German amateur, it has English version ... and VK1RJ has easily downloaded it onto a partition on his hard drive and has it happily running on a laptop with a 4 Gig partition.
Located on the disk are a raft of amateur radio programs ... for psk31, Morse, SSTV, etc. As well there are the standard Linux programs including an office suite and various graphics and multimedia manipulation programs.
Additional programs can be readily downloaded from Knoppix and/or Debian repositories.
