[HCDX] info about radio Boomerang
Dear radio-friend,
In this leter you will find some short background information about radio
Boomerang and his operator.
Radio Boomerang is a free radio station configured for transmitting on the
most common frequencies in the medium- or short wave range. Mostly however,
in the 180, 76 or 48 meter band.
At he moment, on medium wave a kind of dipole antenna at 20 meters high is
used. It can be switched as a dipole or as a ?T? antenna. On short wave I am
using some kind of an inverted-V alike antenna.
The power fed into the antenna is about 800 watts. The transmitter that is
mostly used consists of a driving stage containing 10 IC's, 6 transistors
and 2 tubes and a power amplifier containing a single power tube. The so
called modulator for audio amplification is built around 4 triodes in
push-pull. All the equipment (including test- and receiving equipment) is
home made. The QTH is the city of Neede, which is located in the mid-east
of the Netherlands near the German border.
At the moment, I (Arie, the operator) am 45 years old, married, and have two
kids. Furthermore I am working as a computer engineer an I am practising the
(free) radio hobby since about 1976. First only on medium wave (with
sometimes 'big' power) and later on short wave (with less power).
I am not a regular ?program supplier? because I am more technically
interested. Most of my free time I spend with building equipment for
reception and reception measurements like receivers, panoramic adapters and
so on.
Between that I develop and test different kind of antenna systems. This both
in real life and as computer simulations. At the right, for instance, you
see the radiation pattern for the antenna used in october 2003.
Remarks: Best wishes from:
Arie (Operator Radio Boomerang),
Po-box 73, 7160 AB, Neede, Holland.
