Biography

Hi there,

When time permits I am QRV on HF and 50Mhz.

Currently I have only 1 unsymmetrical dipole antenna that operates on 40m, 30m and 15m bands with very little or no ATU. It will easily tune to 60m, 20m and 17m bands.

My favourite mode is CW and I find a great joy in learning it - it is a very slow process though :-)

I use FLDIGI as a logger and occasionally I'd use its digi modes too.

QSL cards via eQSL and I will post direct if asked. If you haven't received my QSL card or like to contact me -please send an email.

My first ever DX contact was made….. on a CB radio, 27MHz – 5W TRX Superstar 360FM. Assisted by my brother, I made a contact with an Italian station located in Pantelleria. I could not understand their language and managed to write down the QTH – without understanding what it actually was! It was a long time ago before the internet became available to us and I had no interest in geography… Call it a learning curve.

Our first contact with a hamradio operator was actually made on a CB radio. It was Bohdan SP9EYY, later SP9VJ. He invited us to his home radio shack and demonstrated his kit to us. For the first time we have seen RTTY and CW in action. At the time Bohdan had Commodore C64 to run digital modes.

Together with my brother (later SQ9BZY) at the age of 18 I have passed my hamradio exam and received a callsign SQ9CWG.

The exam was taken in Piekary Slaskie and I still kind of remember it! We were going from one little office to another answering questions in different categories. With our first licenses we could not transmit on the HF bands and were power limited to 50W.

Our focus was on the 2M band. Thanks to our dad, who later passed his exam too and received a callsign SP9UPV, we were in a possession of the old Radmor portable transceivers FM-315. They required crystals and the power was varying between 500mW to 1W depending on the device.

Our next stage was to build a 2m FM transceiver of scrapped chassis and building blocks of the mobile Radmor 3011 transceivers.
This time we have replaced the crystal channels generators with our first ever digital synthesizer built on nothing more than simple gates and transistors :-) . At the time we had no tool to spectrum analyze and tune so the process was more like the blind folded archery!

Later we upgraded the digital part to a 8051 microcontroller based unit with 2 lines LCD display and upgraded the synthesizer module.

On the roof we had a home brewed 2x5/8 vertical and later added another hand made 7el Cubical Quad on the horizontal polarisation.

In the mean time we played with a Packet Radio. We interfaced our Atari 65XE running SP9TCE software with an old FM-315.

Some time later my brother built his first SSB radio based on the design from the "Poradnik Ultra Krótko Falowca" book of Zdzisław Bieńkowski. We used that transceiver for our first long distance SSB and CW QSOs. I was lucky enough to experience Tropospheric ducts and Auroral openings on the 2m band! I did my first tropospheric QSO with a portable 500mW station over 500km away.

Later I've upgraded to a full license with a power limit of 500W.

I must not forget, SP5WW - a home made HF radio that was given to us by our colleague and needed some work done. For me it was a good experience to touch and feel a radio with QQE06/40 valve glowing a blue mist when transmitting.

On that note, always remember to isolate a power supply before you attempt to discharge capacitors keeping 1kV of fresh juice - it may cost you a life of your favourite screwdriver :-)
