history of PD0PZR.
story goes back from the year 1960 till 1970.
I was born in the year 1959 in the big city of
Rotterdam. So around the year 1968 I will start with
electrical, to made a receiver called “little jam jar
receiver”. It was just the name, it wasn’t made in a
jar. I made this receiver with the well-known Amroh
coil, a OA81 diode, some resisters and a very long
wire antenna. How surprised I was when I could listen
to the radio and received AM broadcast stations
without any battery. The strongest station I could
listen to was a pirate station called Radio Noordzee
International, transmitting from a ship in the North
Sea, the Mebo 2. That time my radio interest was born.
Quickly, a earphone was not enough and I decided to
make a amplifier for this
radio receiver so I could listen in my bedroom to the
radio by a loudspeaker. Thus I have some knocked
together that time. The next serious project, a few
years later, when I was about twelve or thirteen years
old, the FM Broadcast frequency seems to be popular. I
decided to make a FM transmitter. That time you could
find me most of the time into the library to watch
technical information. The first FM- transmitter
was made. Transistors I used were AC126 and
AF128, after all I bought the microphone at the
marketplace. And look, it works! Completely instable
but enough for at least 500 meter distance, with an
antenna who wasn’t made for a special frequency, but
it doesn’t matter. And it was illegal, but that wasn’t
my problem, I didn’t know (hi). The frequency between
100 and 108 MHz are not used that time so we could use
it as a pirate station. In the years 1975 / 1980 this
100MHz will be very popular also for me. Not even for
bringing music, just for make contacts with other
100MHz (pirate) stations in the whole country, Germany
and Belgium. I was very active at that time. The sky
was the limit and so the HF power. Nothing was enough.
The first amplifier was just a MRF 238, but the end
was a amplifier 2 x 4cx250B. Enough to make 1Kw. The
standard FM broadcast receivers became a modification
into the mf, to make them more selective.
I could practise this hobby without any problems, the
(communicate) authority were not interest in me and my
Everything we used was home made because nothing was
to buy in the shop, or it was sold from a other radio
In the early years ’90, the local en regional
Broadcast stations took a place into the 3 meter band
and this was the beginning of the end from 100-108MHz
pirate stations. Most of them went to a other
(pirate)band in the uhf frequency, 480Mhz, and so I
did. Just low power in audio and video transmission.
I decided to go for my ham licence in the year 1989
and from that time I have my call sign PD0PZR. In the
beginning just for 2 meter, 144Mhz, later, around 1995
also for vhf 70cm. I was very active with packet radio
as a little node station, 1k2 and 4k8. After the big
bang (=internet start) nobody works packet anymore,
and also 2 meter is very inactive since that time.
After a long break, because a serious illness, I took
the hobby again in the years 2005.
Now, 2006 we can also operate in the HF frequency 10,
20 and 40 meter bands as well, so we picked up the
step forward, springtime 2007, I have to replace all
my antennas and also change the complete tower because
of the hf antenna. How some works, you can find it on
my website. Just click the link “antenna renovation
2007” somewhere on this page.
one year later, 2008, I decided to change my 3 element
Fritzel for a 3 element SteppIR antenna. How I made
it, you can see on my website. Just click at the end
of this page on the SteppIR link.
