Biography

Hello! Thank you for reading my home page.

I got my license (old call sign ON1KYM) in 1984 and changed my new call sign ON4IJ in 2016 to keep the call sign of my father Richard Flamée silent key in 2012. My Class A license is recognized according HAREC.

I was born in December 1960 and I'm an Industrial Engineer in Electromechanical domain and specialized in Electronics and Radio Frequency. I'm working as employee with a function of technical consultant at a company of 20 persons in Belgium which is involved in electronics industrial equipment and radio remote control equipment for rolling cranes and locomotive engines in the Steel Industry.

After a gap of 20 years radio silence, I restart amateur radio activities since 2016, especially at the radio club ON5VL founded in 1925 at Liège, Belgium. I am QRV on 6 m, 2 m, 70 cm and 23 cm with a FT-736R and actually w. a tri-band vertical antenna Diamond X6000A (some other antennas are prepared for the next future).

Finally, I am fascinated by the radiofrequency test and measurement second hand instruments of Hewlett Packard within the great years of the end of XXth century. For these famous instruments, you can find easily the complete Operating, Service and Calibration Manuals; that helps a lot. To improve the RF knowledge base, you can read many Application Notes about these models. Since some years I invest in some of these RF equipment to improve the technical aspect of my Amateur Radio activities.

It begins slowly but surely (I hope) to become my Ham RF Lab with already the following working models I use (for the most part calibrated): HP 8563E Spectrum Analyzer w. HP 85645A Tracking Source and HP 11974A 40 GHz WR28 Preselected mm-wave Mixer; EPM-441A Power Meter w. some HP 8480 Series Power Sensors and w. HP R8486A 40 GHz WR28 Power Sensor; HP 8753C Vector Network Analyzer w. HP 85047A S-Test Set and w. HP 85046A Opt. H20 Mixer Test Set, HP8625A Synthesized RF Sweeper and HP85032B Calibration Kit (of course); two HP 8662A Signal Generator w. Anzac combiners, some circulators, HP 360A,B,C,D and HP 11678A LP-Filters (the all for IMD Measurements); HP8757C Scalar Network Analyzer w. HP 83620A Synthesized Sweeper, HP 83554A mm-wave Source Module, HP 85025A Detectors, HP 85027C,E Bridges, HP R85026A 40 GHz WR28 Detectors and some other WR28 accessories among others: Splitter, Directional Couplers, Calibration Kit, Isolators, Bend, Twist etc.; HP 8970B Noise Figure Meter w. HP 8971B Noise Figure Test Set and w. HP 346A,C Noise Source; HP 8901B Modulation Analyzer; HP 8903A Audio Analyzer; HP 3326A Two Channel Synthesizer; HP 8131A Pulse Generator; HP 33250 Function/Arbitrary Waveform Generator; HP 53230 Universal Frequency Counter/Timer; HP Z3801A Frequency Standard GPS Receiver; HP 5087A Frequency Distribution Amplifier. I think it is a good start with these equipment isn’t it ?

Please visit the ON5VL Ham Radio Club Web Site: www.on5vl.org/ you will find within the section "Articles" and then in the subsection "Electronique" some of my technical publication. Usually, I try to write this year a new technical publication a month. These article are filled with plenty of pictures and intentionally written in French thinking about French speaking Amateur Radio all over the world.

Best 73's.
