amplifier

An amplifier is an electrical device, which will increase the voltage, current and power of the applied signal. Amateur radio uses both transistor and electronic amplifiers (the tubes are more palatable at higher powers and have better voltage and current ratios).

Thank you for visiting this portal designed for all radio amateurs from OM and OK.

We bring you current information from the amateur radio world, however, we do not want to be narrowly focused on one area, therefore, new articles from each circle will be added to these pages practically daily, which concerns us HAMs.

We would ask everyone, who can contribute their articles, ideas, stimuli, to be actively involved in building this portal. It's not a portal to those, what they created it for, but for all of you.

If you have any questions, please contact the administrator at: admin@cq.sk. Thank you and we look forward to meeting you at the band! 73 by OM0RX and OM0AAO.
