The NASA iPhone app was created by the New Media Team at NASA's Ames Research Center in Mountain View, California. The app is available free on Apple's App Store — and can be downloaded here
The app was created by Appirion a firm that specialises in software for mobile phones.
While iDriver is believed to be the first car controller devised for the iPhone, it follows a spate of technological advances aimed at creating "autonomous vehicles" capable of driving themselves and reacting to their surroundings.
I can see it now, you are sat at your desk in work and the telephone rings. Your wife wants the car so you get out your iPhone and drive it back home while still sat at your desk. Or maybe you stop for a drink on the way home and then have you wife drive even though she is back at home sat in front of the TV. Somehow I don't think anyone trusts technology that much to allow it on the streets but we can dream.
Nickie's Father was somewhat surprised when he came home to find an OFCOM engineer waiting for him and had to check is credentials thoroughly as he found the idea that something in his house was interfering with landing aircraft bizarre. He said ''Then we went inside and he followed the signal using a special reader to my son's bedroom and his booster aerial - I was absolutely gobsmacked.'' Mr Chamberlain was told to dispose of the £15 aerial, which Nickie had been using for two years in the bin.
Nickie said: ''When I found out what happened I was upset because I couldn't watch cartoons or the television for a while - but it's better than causing a plane crash.''
National Air Traffic Control said: ''The planes have multiple back-up communication systems and this is not something where any passengers were in any danger. Obviously safety is our major concern.''
Looking at the picture in the Telegraph the antenna is a Telecam TCE 2000, which is sold by Argos and various supermarkets in the UK as both a set top antenna for around £2.99 and together with signal booster for around £17.99. OFCOM say the problem is not common but bearing in mind the hundreds of thousands of these sold I would ask how many similar devices are causing interference on frequencies such as the amateur bands where complaints are less likely to receive a visit from an OFCOM engineer?

El Silbo apparently takes its name from Silbo, which is a sort of a whistled language that's used on the isle of La Gomera (Canary Islands) to communicate across wide mountain valleys. The best DX is apparently 2 miles, or just over 3km.
Roger G3XBM points out that this sort of thing has been done before with a 1955 article from Time magazine. The item tells how the Army Signal Corps has developed a radio transmitter that needs no energy except electricity generated by the speaker's voice. The inventor, George Bryan managed to transmit 600 feet with a device small enough to fit in a telephone mouthpiece but suggested a range of a mile was possible.
Roger says over at his blog that Michael is also working on a receiver that uses RF harvesting techniques, which if I am correct means taking the received RF from a high-powered broadcast station and using it to drive the amplification stages in an amateur radio receiver.
Maybe it is just me but I feel these ideas may lend themselves to the development of future innovations such as an RF powered watch or as a way to power nano-technology. Just imagine tiny robots powered by RF from a BBC radio one or how about a receiver in your car powered by the noise from the engine. The only limitation is our imagination.

It may all be done tongue in cheek but there already some serious survival tips over there and in the discussion pages words like 'Ham Radio' are being banded about. This is a chance to get the message about amateur radio across to people who would not normally come n to contact with it. As it is a Wiki all the articles are member written so get over there and tell everyone all they need to know about becoming a radio amateur before the zombie attacks start. When it happens can I have Alice (Milla Jovovich) on my side?
Get a radio history lesson here
I followed the link above from Southgate ARC newsline and although the site is somewhat dated in appearance the potted history of the science and scientists behind radio is excellent. Just a nice little taster that might get you wanting to read a bit more about how it all started. I was a little disappointed to find such a short passage on Nikola Tesla whom I find exceedingly fascinating, but it did give me a few other names who’s stories I know little about and may be worth reading up on.
After 24 years at their current location in Sea Street they are due to be in their new home by the 9th of November 2009.
Icom UK’s new address will be:
Icom UK Ltd
Kent CT6 6GZ
All telephone numbers and email addresses remain the same.
Despite what Icom are saying on their website and bearing in mind the upsets in the UK with the postal strikes I would maybe let the dust settle a while before I sent or ordered anything from them. I suspect this also means we cannot expect any price cuts on Icom gear in the near future.
If anyone at Icom is reading this remember we do not charge for doing equipment reviews at CQHQ and we love Icom gear. Well you have to try don’t you!
Note: DX Hamspirit servers appear to have fallen over due to the heavy demand caused by the devastating news.

Do not get me wrong on this I have no axe to grind, you are whom you are and we are all strange in our own way. I would hate to be considered normal as that implies being somewhat average and I do not like to think of myself as average, who does?
In the world of amateur radio I have met some odd people but only a couple of them have been so odd that I would go out of my way to avoid them. In general radio amateurs have been some of the nicest and most helpful people I have met. We all tend to have differing interests within the hobby and our expertise and different life experiences leads to some rich and interesting discussions on the air and over a pint at the radio club.
There has been much discussion about how to get new blood into the hobby and I must admit to being in two minds as to whether or not the present system of the Novice, Foundation and Full licences is doing its job. We are seeing more and more youngsters coming in to the hobby which is a good thing but they lack both technical knowledge and life skills, which when combined leads to, in a lot of cases, a complete inability to say anything the remotest bit interesting.
I admit I can be as boring as anyone on the radio, you just have to listen to the conversations I have with my wife on the local 70cms repeater as she drives home from work; “What shopping we need?” or “Do the kids need new shoes?” and “What is for tea?” It is possibly unfortunate for some locals that my life is lived on the amateur bands like some badly written soap opera. I have few secrets as a result but what you do not get is a stroke-by-stroke description of painting the bathroom wall or how I had the vet around to give my cat an enema. Occasionally I do have what I call a ‘white page day’, these usually happen when I am slightly jet lagged from working the night shift. A white page is what a writer stares at when he has writers block and my ‘white page days’ are when I sit there with a microphone in my hand and just cannot think anything the least bit of interest to say.
So I ask you, do we have to put up with those for whom every day is a ‘white page day’? Is it simply that by dumbing down the amateur radio examination process we have dumbed down amateur radio? Only time will tell. The answers lie in new licensees obtaining knowledge by listening on the bands, by reading books, magazines and Internet posts, experimenting and building equipment and antennas. Only then they will become interesting enough to be considered strange and strange enough to be considered interesting.
Who is the angry seller? you ask. It is this guy...
There is 22 watcher and no bidders !!!---- if there is no bidding within the last few days of the sale i will remove and sell it for scrap.
Like anyone gives a monkey's if he sells it or not. Anger management classes anyone?
I have lost count of the number of times I have seen this sort of thing. Don't these idiots understand that most eBay bidders leave it until the very last second to bid on anything or that even if you a selling something nobody wants you can still get a load of people watching who simply want to know if it is worth trying to sell a similar item that they have.
In this case the guy was selling some aluminium mast poles and was a fairly local 'buyer collects' so I might have been interested if he had said how big the poles were instead of "You will need a big van." He obviously does not own a tape measure.

Visit http://www.swl-registry.com for more details.
Many radio amateurs started out as shortwave listeners before becoming licensed themselves and many do still spend time listening to the shortwave broadcast bands. The listening pleasure was always made a little more exciting because by knowing that most people do not even know what it is you felt like you were part of an exclusive few, even though in reality millions may have been listening. I used to enjoy comparing the broadcasts by Russian, Chinese and American stations with those put out by the BBC. It gave a broader more balanced view of the world when you realised every one of them was biased in some way and the truth could probably be determined by an extrapolation that took in the similarities and differences of any report based on each stations political stance.
SWL's of course listen to more than just the broadcast bands and as a radio ham I always find it rather nice to receive SWL reports(QSL cards)particularly when the report was from much further than the actual contact. I do hope Clifford's service takes off and encourages more people to become shortwave listeners and maybe through listening to become hams. In this age of the Internet and computer games the hobby definitely needs a shot in the arm.
Success Easy has just converted all their CW training CDs to MP3 downloads. To celebrate, they are offering 25% off during the rest of October. All the CDs were produced by Peter O'Dell, WB2D, who is a professional hypnotist and trainer. It is a fast, fun way to boost your CW speed, and this way you do not have to pay any S/H charges and you get 25% off. The link is http://www.success-is-easy.com/HamDownLoads.htm and the coupon code is OctoberFest. --K0CS
As someone who grew up with a father who was a professional illusionist I know all too well that hypnosis is no more than a stage trick and has no basis in reality. The whole thing works on the basis that a percentage of the population are completely gullible and will believe they are under the hypnotists control combined with use of plants in the audience. I find it somewhat surprising that the majority of people I speak to believe this bunkum. It is time someone in the know stood up to the charlatans the way Houdini stood up to Spiritualists. Not that it would make much difference as people are still taken for a ride by those nutters.
Undoubtedly some people find these so called self hypnosis things helpful. I have listened to a few myself and they usually offer advice on positive thinking that is quite logical, but then they tie it up in bunkum. There is no self-hypnosis or induced trance except in the mind of the gullible who believe they are 'under'. Some will say that if they believe they are hypnotized then they are but brain scans of people supposedly under hypnosis show otherwise.
Hypnosis is at best a placebo effect and at least it has persuaded thousands of people to give up smoking, but it is still not real. Many otherwise intelligent people such as those in the medical profession may be fooled, but it is just another pseudo-science proffered for sale by Snakeoil Salesmen. If only these guys would come clean and just sell positive thinking without the fake mysticism I would be happy, but in this world people need a crutch and the slick talking grease ball with the pocket watch will keep selling his placebo crutches.
I was quite pleased to see the number of sceptics that have already posted to the thread on QRZ, I think it shows most radio amateurs are men of science and not easily suckered. I now await the case for the defence starting with the one that starts "I bought these CDs yesterday and am already up to 40 words per minute."

One of the early UK areas to experience the turn off of the analogue signals is Devon and Cornwall and holes are starting to emerge in the digital system. During periods of only lightly enhanced propagation viewers are losing their local BBC 1, 2 and ITV channels swamped with signals from Welsh digital TV repeaters. Viewers report watching a program in English only for it to switch to Welsh and back again. Sometimes the switch is a brief flicker for a few seconds and at other times they see segments of a couple of minutes at a time. Even when both English and Welsh stations are transmitting the same program there is a slight time difference which gives an effect similar to a scratched record jumping back and forwards. I think the first good lift after the switchover will see similar problems nationwide. I am glad I invested in Sky satellite TV along time ago.

A reminder that the 23rd North Wales Amateur Radio Show takes place on Saturday & Sunday, 31st Oct & 1st Nov 2009.
The organisers say they are pleased that the 2008 Rally which was held at a new venue and received a great response from visitors and traders alike will be continuing in 2009. The new site is the brand new high school in Llandudno, Ysgol John Bright, Maesdu Road, Llandudno. LL30 1LF. The school has two large halls for the show and ample free parking on site. It is very conveniently located, when you come into Llandudno down the dual carriageway you now turn left at the Links roundabout (instead of right for the old venue) and it is approx 1/2 mile down the road just after a mini roundabout.
Click here for a map of the venue location
Any traders interested in booking space at the 2009 show please contact the Rally Organizer, Liz Cabban, GW0ETU - firstname.lastname@example.org 01690 710257 or the Club Chairman, Mr Ron Roberts on 01492 592 884
I do hope that what was once one of the best radio rallies in the UK can regain some of its former glory. The new venue certainly has the room and the potential to become home to a brilliant event. Last year was a good start but I was a little disappointed at the lack of support from visitors and traders alike, but considering the lay off the organisers did an excellent job.
As a child I had vivid nightmares but over years I learned to control what I dream to some extent and when I dream these days it is usually an exciting but confusing roller coaster ride. I only really ever had two consistently reoccurring dreams; in one I was being chased across a barren post apocalypse landscape of smoking piles of rubble chased by a 100-foot high robot whose chest was aglow with a furnace that provided its power, in the other there was a beautiful woman at the top of a staircase who I could never quite reach. My mother always said that the young woman was my guardian angel, which I found quite a reassuring idea. Of the other dream my mother just said I had been watching too much DR Who and Star Trek.
I know that many people do not dream the way I do, and it is probably a high percentage of the population, due to the arguments I have had with people who did not believe anyone even dreams in colour let alone anything else. I really do have extremely lucid dreams at times and one such dream that I discussed in length with my family and friends was so like the plot of the Matrix that watching the film left me stunned. So much so that after seeing it I went out and bought the DVD and watched it ten times in a row. It was like someone reached in to my head and stole my memories before putting it in to a film.
I was working on the nightshift last night and when I finally got to bed this morning I had a lucid dream. In this dream I was being shown a car battery. It was about 8 inches by 4 by 2 and the person showing me said it was 160-amp/hour and used crystal technology. It was also extremely light. I asked the chap who was wearing a lab coat about how it worked. He said that the battery contained a liquid crystal and that as current was drawn the crystal reverted to a solid form and that to recharge the battery just required heat. In a car the heat in the engine compartment would be enough to recharge the battery. He continued by saying that at home placing the battery in my airing cupboard would revive it. I asked him what the crystal was but the dream faded before I got my answer.
Imagine my surprise when I got up and read my emails this morning and saw an email from Keith GW4OKT who is working out in Sakhalin Island at the moment. The email said ‘Steve, One for your blog? This link will take you to a story about a new technology for batteries.’ The link was to an article in the Jerusalem Post about a new kind of portable electrochemical battery that can produce thousands of hours of power. The unique battery is based on liquid silicon as a fuel that reverts to its original sand. It is still under research by Prof. Yair Ein-Eli at Haifa's Technion-Israel Institute of Technology in collaboration with Prof. Digby Macdonald of Pennsylvania State University in the US and Prof. Rika Hagiwara of Kyoto University in Japan.
It seems they are stealing my dreams again, now where is the aluminium foil so I can make a new cap.
Julian seems to have walked firmly up to the hornet’s nest and given it a damn good kicking and I must say I agree with him 100%. There is nothing wrong with CQ100 but the way the thing work is all a bit silly.
I have heard one or two regular nets using it (or something similar) on 80m when the band was a bit dead to keep those on the reception fringes in the loop and I have heard stations come on to 20m who arranged a hook up over either CQ100 or Echolink so these services do have their place in real radio too.
If you think that maybe you might one day hook up and get into an interesting QSO with a DX station that you might never hear again. These VOIP services give us the chance to finish a conversation that was lost to fading signals.
Personally I have only ever bothered with Echolink for the purpose of listening in to distant repeaters when things are quiet on the ten or so bands I usually monitor. At least that does not have a daft radio style interface and most users don't pretend they are on the radio when the make a direct link.
I occasionally rant on about how repeaters are not real radio and often I am using a repeater at the time, it can be fun. It usually happens when some idiot tells me I am 5/9 - Duh! No the repeater is 5/9.
The truth is real radio or not repeaters and VOIP can be fun and the whole idea of any hobby is to enjoy ourselves. What worries me more is the divide and conquer syndrome; There so many different aspects to amateur radio that we become thin on the ground as we all practice our personal areas of interest. If we lose some to Echolink, some to CQ100 and some to D-Star etcetera soon the bands will start becoming a desert like 23cms. You at one time used to struggle to find a space on two metres on either FM or SSB in my area now you struggle to find a contact.
Over the years I have known a lot of people who helped my interest in the hobby grow from being an enthusiastic beginner to being someone whom others sometimes ask for advice. Some of the people who I counted amongst my best friends in radio were in the twilight years of their lives and I gave the best advice. A lot of them are no longer with us and I miss them all and their friendly reassuring voices as we put the world to rights deep in the night.
I have lost count of the number of times I have been stood in cold silence under a grey sky listening to the last post being played. It leaves an empty feeling inside but when, as had happened far to often in my life, a younger person happens to fall victim to illness or accident it is much harder to come to terms with.
The news that a family of three died in Palm Bay, Florida while trying to raise an amateur radio antenna leaves me shaking my head and asking “why?” What a tragic waste of life! No one should die as a result of what is after all just a hobby, let alone a family. Although I am thousands of miles away I feel as if it was someone I knew and a cold tingle run down my spine thinking what the remaining family members are going through.
The tragedy occurred when 55-year-old Melville Braham, 49-year-old Anna Braham and 15-year-old Anthony Braham were raising a fifty-foot amateur radio antenna at the home of Melville's mother Barbara's house. They had been working on the antenna for sometime and did not stop when the sun set as they raised the antenna they lost control and it fell on to overhead power lines. The impact sent 13,000 volts of electricity through the pole the three were holding. The antenna was being erected because Melville's mother Barbara KJ4KFF used amateur radio to keep in touch with the rest of the family back home in Jamaica. Barbara and granddaughter Melissa heard the explosion and called the emergency services. Neighbours also rushed to the scene after hearing the explosion.
For anyone who operates portable a lot it is a lesson that needs to be heeded. There are not usually overhead power lines where I tend to go with SOTA but they are not completely unknown especially where there are commercial transmitting stations atop the hills. Maybe it is only through good fortune that I have not been a victim of a similar incident. Only a couple of months ago I was erecting a fishing pole mast unaware of a overhead power cable hidden from my position by trees, fortunately my wife spotted it and we had to move the whole station out of the proximity of the cable. Hopefully that near miss and memory of the above tragedy will help me avoid repeating the mistake. The irony of my mistake is that on the carp/squid pole there is printed a warning of the dangers inherent in overhead power lines. In the UK the type of pole I use is often used for fishing on canals and for some reason power companies seem to love running their overhead power lines parallel to them making this sort tragedy almost common place. Thankfully it is a rare occurrence in the amateur radio community.
Please be careful out there. May you all live long enough for the mourners around your graveside to say, “Well he/she had a good innings!”

"The team has safely arrived on Midway Atoll at 07:00 UTC 12 OCTOBER"
"At daybreak we start assembling our antennas and stations and will rush to put our stations on the air."
OS spokesman Paul Beauchamp said: “Cartography is a fine art, but the colours that have become so familiar to most of us are actually among the worst possible choices for those with colour blindness. By using our new mapping product, called OS VectorMap Local, councils and businesses will be able to create styles especially for colour-blind people that we hope will make life easier.”This should mean more people can enjoy the great outdoors, back-packing and Summits on the Air with increased confidence.

After changing the power level, the first transmission is always at high power. The selected power level is only produced on the second and subsequent transmissions.
I don't know if this is a general fault or something that only affects my radio. I would be interested to know if anyone else can confirm my findings.
So if you have one of these little beauties please try it out and let Julian know via his blog. Obviously the same applies for the non-EU versions too.
Read G4ILO's first impressions of the MFD here
K4M will be active from 9th - 19th October 2009 from Sand Island (Reference numbers: USI OI-011S and Grid AL18). A multi-national team of 18 operators consisting of Joe AA4NN, Franz DJ9ZB, Max I8NHJ, Kevin K6TD, Kimo KH7U, Craig K9CT, Don N1DG, Tom ND2T, Paul N4PN, Tom N4XP, Arnold N6HC, John N7CQQ, Dave WB4JTT, Charlie W6KK, Bruce W6OSP, Art WA7NB, Joe W8GEX and James 9V1YC will be active from 160 to 6 metres with 5 to 6 stations on air.

M3 "So wots yer best DX then?"
M1 " ZL is the furthest"
M3 "Where's that then?"
M1 "New Zealand"
M3 "Wow! Any other good ones?"
M1 "I managed to work Antarctica once, got in before the pile-up started"
M3 "Antarctica! Cool!"
M1 " Yes Antarctica is very cool or so I am lead to believe."
A long pause and then... M3 "HAHA very funny!"
Another pause and then... M3 roaring with laughter "I get it now."
The familiar voice of a G1 then broke in with "God help us!"

In a unrelated and somewhat older incident I read that a Glider club which complained of interference was fined $9000 when it was found their licence expired in 2004. That reminds me of the parable of a splinter in your brother's eye, and how removing the log in yours first is a good idea.
I personally (as in face to face) know about thirty local amateurs that went to Friedrichshafen for Ham Radio 2009 and many more who I know only on the air. Possibly it was the £10 flights being offered by Ryanair that persuaded them and the airwaves buzzed for weeks after with tales of the experience and the purchases. The three-day event at the Friedrichshafen convention centre attracted 17,400 amateur radio enthusiasts from around the world. In comparison I have so far only heard three people talking about the National Hamfest one said "A bit of a waste really, all I bought was some PL-239's" and when asked by his mate what he thought of the rally he said "It's a big venue!" and then changed the subject. The second said that he had been going to go but decided it was to far from Warington in Cheshire and the third said he had been in Lincoln over the weekend but forgot it was on. For those of us on this side of the UK it was certainly cheaper to go to Friedrichshafen than to Lincoln.
I decided to have a look for comments on the net as to how it all went or how many people attended but all I found were a few photographs showing what seemed to be almost empty halls. I hope it was not as bad as the impression the photos gave. I did find a site dedicated to suggestions for improvements of next years event and I urge anyone who went to leave some comments at http://hamfest.wordpress.com/ as well as on this site.
The next National Hamfest is planned to be held on October 1st & 2nd 2010 at Newark Showground.
I don’t know who is to blame for the clash as such but this time the contesters have taken the high ground and acted as both gentlemen and good radio amateurs by declaring contest free zones for the Scouts to use. No one can guarantee an interference free zone but at least they should be contest free.
The contest-free frequencies are:
Best of luck to those running a JOTA station from CQHQ
See the announcement here
World Scout Frequencies http://www.scout.org/en/information_events/events/jota/world_scout_frequencies
Radio Scouting - JOTA http://www.scout.org/jota
While I am sceptical of the claims being laid out for it and slightly worried that some may see it as the alternative to properly secured systems it looks like as part of a fully integrated security program it could well have a great future. The next question must be where can I buy some? As a solution to keeping some of the stray electromagnetic mush that plagues almost every home in this modern world out of my radio shack a couple of tins of paint sounds like a good investment. Unfortunately it does not do anything about my neighbour generated RFI entering via my antennas, so I still need to move out in to the wilds if I want to reduce my noise floor.
Well until our local DIY store starts to stock the paint we could always try papering the walls with aluminium foil as I am sure that would work just as well and also has the advantage of reflecting heat back into the room. While you are there you can fashion yourself a little foil hat to stop them probing your brain with their satellites.
