The Ham radio category covers amateur radio technology, operating techniques and practical station building. Topics include HF, VHF and UHF communication, antennas, transceivers, tuners, digital modes, portable radio, SOTA/POTA operation, propagation, repeaters, SDR receivers, feed lines, grounding, station accessories and real-world radio performance. The articles are written for licensed radio amateurs, beginners preparing for the hobby and technical readers interested in long-distance radio communication.
What is the ISM band really? The ISM band (Industrial, Scientific and Medical band) refers to radio frequency ranges that were originally allocated not for telecommunications, but for industrial, scientific, and medical equipment. Devices in these bands can operate with relatively high power and cause interference, since their use does not require a frequency license….
During hiking, camping, hunting, mountaineering, or bushcraft activities, communication safety is often a matter of life and death. We frequently venture into areas with no cellular coverage, where there are no towers and modern digital tools—such as smartphones or GPS—are of little use. In such situations, traditional radio communication, especially FRS-based walkie-talkies, becomes invaluable. But…
Hiking in mountainous terrain and QRP amateur radio operation are increasingly overlapping hobbies for many enthusiasts. For these operators, the challenge lies not only in conquering nature but also in achieving efficient communication with minimal energy consumption. QRP, or low-power radio transmission, is one of the most exciting branches of amateur radio. It requires not…
For many, CB (Citizens Band) radio is a tool for local and short-range communication—favored by truckers, off-road enthusiasts, and hobby operators. But from time to time, the question arises: is it really possible to establish genuine long-distance, or DX, contacts via CB radio? Can you actually reach across continents using the 27 MHz band, or…
What changed since the launch? The Icom IC-7300MK2 is no longer just a newly announced SDR transceiver. After the first wave of excitement, early user feedback, pricing information and real-world comparisons have made its position clearer. It is not a radical reinvention of the original IC-7300, but it is a meaningful modernization of one of…
In amateur radio circles, countless myths, half-truths, and real tricks are circulating. One of the most frequently debated topics: does the length of the coaxial antenna cable really matter? When is cable tuning useful, and when is it unnecessary? The Cable Length Myth – And What’s Behind It The Basics of Impedance TransformationA quarter-wavelength cable…
