Amateur Radio, a hobby without frontiers
(By Giovanni Converso, HB9HFL, Switzerland)
What is amateur radio? Who are the radio hams? How can they communicate
on the air waves in this” internet” era?? The following article attempts
to answer these questions. Ham radio is also a token of friendship and of
real-life experience. Technique alone would not suffice if not directed
by inner feelings…
Nowadays radio communication has become so common that no one is surprised to hear,
by simply pressing a button, a radio broadcast... But only few
know that it was discovered by the first radio amateurs. In fact, it
was in 1896 that the most famous radio amateur of all, Guglielmo Marconi,
acquired his first patent for a wireless communication system. Radio
was born!
For more than a century people have been communicating on the radio waves
with home-made transmitters and receivers: they are the radio hams.
They are men and women of all professions, all social status and all age
groups, interested in radio and telecommunication techniques.
Radio amateurs can establish contact with other amateurs’ world wide, they
can discuss, communicate by telegraphy or teleprinter, exchange e-mails,
pictures, files, etc., in the bands of radio frequencies specially assigned
to them.
Radio amateurs are authorized to build their own equipments and to experiment
with all types of antennas. They transmit either from home, in the
car, boat or plane, or during a mountain race. In mountains they install
relays to transmit their messages. Satellites built by radio hams encircle
the earth...
The radio amateur hobby is a powerful means of bringing people together,
without race, colour, nationality or religious discrimination. I would
like to relate a personal experience lived thanks to the radio.
This story began on the 13th March, 1997 at 6 o'clock in the morning, when
I was exploring the amateur bands of my receiver. Suddenly a very weak
signal caught my attention. I put on the headphones and concentrated
intently on this small voice that repeated some words, then disappeared
in the background, then reappeared seconds later. After some
very careful tuning of the receiver, I recognised it was a radio amateur.
Quickly I turned on my transmitter and tried to call him in English.
The contact was difficult as propagation conditions were very bad.
I understood with difficulty the name “Ivo” and the country: Croatia. It
was difficult to continue the contact so we decided to try again the following
day, early in the morning, on the same frequency (3.753 MHz).
After a few radio contacts with Ivo, always very well appreciated despite
reception difficulties, I learnt that he lived in the centre of the city
of Dubrovnik and that he had only a very modest antenna, just a few meters
of simple wire.
I also learnt that Ivo was blind and had suffered a lot during the war that
had destroyed ex-Yugoslavia some years ago. I had a much sympathy when
he spoke of his family and friends that he could not meet anymore,
as all these people were located in another part of ex-Yugoslavia, to which
access was forbidden to the Croatians. For Ivo, the only means of communication
with them was his radio, as the telephone was very difficult and costly,
and the letter post did not work at all…
So it was necessary to improve Ivo’s radio station, starting with installation
of a good antenna. Friends of mine and I decided to send him a dipole
antenna.
When the package arrived at Dubrovnik Ivo was immediately summoned to the
customs office for explanations and justifications... He was very scared
by the idea that they would confiscate this precious object.
He went to the office accompanied by his daughter Katarina and friend Miro,
also a radio ham. All feared the worse! Thank goodness, the radio
amateur license was valid and Ivo, after signing lots of forms and going
through more formalities, went home, his heart jumping for joy!
The next day he had to resolve the practical problem of installing the antenna.
In fact, how to fix this relatively long wire (20 m) in this conglomeration
of old houses with telephone lines, electric wires, water pipes, clothes
lines, and all whilst being without his sight? Fortunately Miro and
Katarina were there.
On 27th March 1997 at 6 o'clock in the morning, I tuned my receiver to the
frequency of 3.753 MHz... A few seconds later Ivo’s voice appeared
loud and clear. The contact was excellent!
The following days, Ivo made contact with the stations on the other side
of ex-Yugoslavia, mainly with family and friends. With the new antenna,
communication worked wonderfully! Much better than the telephone!
Ivo and I contacted each other regularly on the frequency of 3.753 MHz.
We are not alone anymore. Several other radio amateurs come regularly
to this meeting place of friendship and solidarity. (It is now known
as The Euro-net.)
