The main activities are electronic service (SMD and CMOS technology) in radio communications where I program and repair (up to level SMD components) radio-stations “Motorola” , “Yaesu” , “Kenwood” , “Icom” , “Maxon” ” including make and maintenance repeaters with “Procom” and “Maxrad” antennas. Also I had to make install radio communication equipments and make telephone networks with “Panasonic”, “Siemens”, “Samsung”, “Topex”, including their program and maintenance.I make computer networks and surveillance systems with cameras and DVR , connected to the Internet ; repair (up to level electronic components) inverters , converters , welding inverters (Lincoln,Esab,Ergus E250 ,E320 ;Telwin technology 220/hd ) and power generators 500 va -10 kva (Einhell , Honda ). Making the connection at the mains. Complete insulations test on circuit, Involved also in repair and maintenance related to the electrical and electronic devices and equipments .I wired the old installations and the new one where was necessary ,after the blue print .Some time was necessary to change or replace the old cables or make repairs (junctions ,terminal ends of the special cables) I pull the cable in all the systems (power, control ,alarm ,communications ,DC ,access control ,phones ) Performing diagnostic tests, and troubleshooting system faults and failures, of electrical and electronic equipment down to the component level. Preparation for energizing electrical and electronic installations .I make the commissioning job to the equipment and devices or installations
The main activities was electronic service in radio telecommunications where I repair radio-stations “Motorola GM300, 350, GP300, P110, HT600, P040,GM340,CM140, P040, CP040 “Icom ICF310S”, “IC-F3S” , “Maxon” ,”Kenwood” including make and maintenance repeaters with “Procom” and “Maxrad” antennas. Also I had to make install radio communication equipments (Motorola , Icom) and radar systems (“JRC”) for inland ships ; interface like “Nokia Premicell”, “Topex” for “Zapp” cellular telephones companies and make telephone networks with “Panasonic”, “Siemens”, “Samsung”, “Topex”, including their program and maintenance. Also I had to repair computers and their software. Involved also in repair and maintenance related to the electrical and electronic devices and equipments. I pull the cable in all the systems (power, control ,alarm ,communications ,DC ,phones,)same things I maked in buildings. Mounted and connected instruments and junction box. Test running and commissioning jobs. Preparation for energizing electrical and electronic equipment.
I worked as freelance in services electronic and electric equipments, industrial and home appliances, telephone exchange(Electronic modular switching system “Panasonic KX-T3081, KX-T616, KX- TD1232”), radiotelecomunications .I repaired new and vintage power amplifiers ,video cassette recorder ( electronic and fine mechanic ) ,radio cassette recorder ,washing machine ,TV.
Between 1987 and 1995 I worked in “Promex” S.A. Company, Research department (Department of design and technological engineering), where obtained 6 (six) professional level (by 7 levels). I had worked in electronic control processors (printed circuit board (design and achievement) ,soldering discret components (resistors, capacitors, diodes, bipolar or mos transistors, cmos technology integrated circuits) ,test running and commissioning job) for hydraulic area and multifunctional equipment for excavating machine, buses and naval (hydraulic pump with energy recuperation for oil ; hydraulic propulsion system for buses with energy recuperation ;multifunctional device for road maintenance ; inland ship with hydraulic propulsion ). I wired all the systems on the inland ship or in buildings with all kind of cables, (generators, pumps winch hydraulic or electric, shore power, fire systems, fire monitor systems, rudders systems , DC systems ,engine alarm systems, general alarm systems
