The evolution of amateur callsigns developed over time into symbols of individuals, community, history, and regulation in the world of amateur radio. These unique sequences of letters and numbers allow…
The Kenwood TS-890 transceiver is a powerhouse in the world of amateur radio transceivers, designed to meet the demands of even the most discerning operators. Built with high-quality components and…
Performing the Ameritron AL-811 MARS Mod is simple with a little knowledge and basic tools. The AL811 amplifier is limited to traditional ham radio bands before the modification. For those…
Frequency modulation (FM) encodes information in a radio signal by varying the frequency of the carrier wave. Unlike amplitude modulation (AM), which alters the signal’s amplitude, FM maintains a constant…
During times of war, governments often take extraordinary measures to secure national communication channels. One such measure, taken during World War II, was when the Military Suspended Ham Radio. This…
In ham radio, the automatic gain control(AGC) monitors signal strength that can fluctuate due to atmospheric conditions, interference, or station variability. To maintain consistent audio levels, most modern receivers use…
The Kenwood TM-D750A is a state-of-the-art triband mobile transceiver that operates across the 144, 220, and 430 MHz bands. This versatile radio offers advanced features such as APRS, D-STAR, and…
Understanding S-Units in ham radio, operators rely on signal strength reports to assess communication quality, and S-units play a crucial role in these evaluations. Found on signal strength meters (S-meters)…
With amateur radio power conversion, converting watts to decibels (dB) and S-units is essential for understanding transmitter power, system gain, and signal propagation. Moreover, this conversion helps operators compare power…
Amateur radio operators rely on understanding the properties of HF bands when optimizing HF bands for maximize communication effectiveness. Frequency wavelength, which is inversely related to frequency, plays a critical…
