MIT


MIT (Massachusetts Institute of Technology)
is putting its course material online as OCW (Open CourseWare).

This a great source of knowledge for all of us interested in technology!

Yet another reason not to miss my TV…

Some interesting links:

TV

Good thing I threw my TV out of the shack…
There is a new series of Big Brother being aired here in Flanders…
Do they even find people to watch these things? Can’t blame those playing in it, they all try to get rich and famous. [sigh]

Back to the K2 this weekend!

HAM RADIO IS THE ONLY FAIL SAFE COMMUNICATION SYSTEM IN THE WORLD!

Herald of Free Enterprise
Exactly 20 years ago, on 6 March 1987, the roll on/roll off passenger ferry Herald of Free Enterprise left the Zeebrugge harbour to set course to Dover. Only a few minutes after its departure and due to a combined number of human errors the ship capsized. 153 passengers and 38 crew lost their lives, most inside the ship from hypothermia in the freezing water. This was the biggest non-wartime shipdisaster since Titanic in 1912.

Many lessons have been learned but one lesson seems to have been forgotten… Soon after the disaster got known to the public, normal (telephone-)communications got congested and became inpossible. But HAM’s were there to take over. Soon a network of radio amateur stations was set up under the lead of Claude ON7TK (who later received the ‘Golden Antenna‘ from DNAT and the city of Bad Bentheim).

Today, 20 years later, there doesn’t seem to be any organised network of (trained) radioamateurs to do this kind of tasks anymore. Yes, the Rode Kruis Noodnet (Red Cross Emergency network) still has a website but I don’t know of any radioamateurs in my region that are currently active in it.

During my activities in car rallies I am regularly in touch with Red Cross people of different ranks and they all seem persuaded that their communications systems can handle every possible disaster… [sigh]. For them, us radio-amateurs are only, as the name says, ‘amateurs’ or, translated, children with expensive toys. Certainly, we have come to the 21st century and soon in our country there will probably be more cell-phones (with dodgy ringtones) than people. We have satellite communications, we have trunking etc. But most people don’t realise that the bandwith on those networks is limited.

Of course we don’t regularly have any typhoons or tsunamis or earthquakes in our region, but is this an excuse not to be prepared?

Some of you smart guys will reply:”But we participate in field day twice a year, that is an emergency exercise!” Maybe it is, if you can call running around for 2 weekends to get all needed gear ready (not to forget the barbecue!) being prepared…

And you, are you ready? Or, like most people I know, don’t you even have a working flashlight anywhere in your home?

HAM RADIO IS THE ONLY FAIL SAFE COMMUNICATION SYSTEM IN THE WORLD! but only us HAM’s seem to know it…

Finally some more K2-news here…

I have been looking into my K2-problem over and over and I can’t seem to find anything wrong. As I haven’t got the time nor the courage to take out and rewind the toroids I decided to order them ready made from the ToroidGuy. And, pleasant surprise, turnaround of this order is only 5 days!!! Ordered last sunday (25 feb.) the package arrived this morning! Thanks Mychael!

Now I’ll have to find the time to install them…

To be continued!

Featured blog

Have I mentioned the great blogs of Peter ON6TT? They can be found here in English and in Dutch
For those of you who don’t know Peter (you must have lived on Mars for the last 15 years…), Peter is a honorary member of the UBA (he was the guy who lobbied to get the Belgian contest stations 2 KW
and 2 by 1 callsigns).
During the last 15 years he was active from more DX-countries than most of us can ever dream of.

Moreover listening to Peter handling the pileups from yet another rare location is a joy to the ear.

Friedrichshafen

  • ham radio FriedrichshafenIf you haven’t made any arrangements to go to The Ham Radio in Friedrichshafen yet, the time is coming! Dates this year are June 22 to 24!
    This year I’ll be there again for the fourteenth (yes 14) year in a row! This year we will be travelling with Jan ON4KB, Tim ON5HC, Erno ON6RK and Luc ON7KZ.
  • Messed a little with the FAQ and the disclaimer pages

Links / Operating

Since I threw my television set out of the shack I should have more time to finally find that nasty bug in my K2 but now I spend my time surfing the net… Again I found some interesting links I wish to share with you:

  • Although there is nothing to see related to Ham-Radio you should check these great pictures on the site of Aime ON4AIM:[inside view] and [outside view] (you’ll need Java to open them!). Don’t forget to click your mouse and drag it around to see the full panorama. This is the lighthouse of Ostend on which the ON0OS ATV-repeater is located.
  • Another interesting text for all ham-radio operators can be found on the site of Marc ON4WW: Let’s make DXing enjoyable again. Please.
    Are YOU sure your operating practice is correct? Yes?

Microcontroller / Award

  • I have always been more of a software man than a hardware man and I have been playing with the Basic Stamp on and off for a few years now. They are great microcontrollers but the big disadvantage is that they are *VERY* expensive. During one of my strolls on the internet yesterday I discovered an other microcontroller which can be programmed in a kind of BASIC and which is way cheaper than the Basic Stamp. I guess one of my next projects will be to test the Picaxe.
    To be honest, it looks very promising.
  • I forgot to mention it here but I have also discovered a new award for ham-operators (and even non-hams!). We all know sitting at your desk for too long is not healthy so it is time to do some sports. The ideal motivation therefore is the Polar Bear Challenge. For now I have been doing some walking and some swimming but as soon as my K2 is ready I guess I’ll go out to operate it portable too. Weather permitting I’ll get the bicycle out soon again too.

K2 measurements

Due to some health worries I haven’t looked at the K2 project the last few weeks. Upon ‘deeper’ analysis in the hospital it seemed the worries were far greater than the real trouble. I’m fine now thanks.
So today I started looking at the K2 again and I started with the homework I received from Gary AB7MY at Elecraft to try and find the causes of the spurious signals that come out of my K2 on 10 and 12m.
But, it seems my Digital Multimeter has trouble with the HF-signals. When my K2 is on transmit (on dummy load of course!) it seems to measure voltages even without the leads being attached to anything…. So I guess I’ll need a better DMM or a better dummy load?
