VHF/UHF Antenna Placement in EV (electric vehicles) presents unique challenges. Unlike traditional gas-powered vehicles, installing transceivers in EVs generate more internal electrical noise, have limited metallic body panels, and carry…
How soil affects antenna performance, it plays a crucial role in determining its efficiency, particularly for vertical and ground-mounted systems. Soil impacts the ground conductivity and dielectric constant, both of…
Toroid mix plays a critical role in the design and performance of baluns and common-mode chokes, especially in ham radio and RF applications. The key to effective performance lies in…
HF radio propagation relies on the ionosphere to reflect signals back to Earth. Because of this, environmental and atmospheric conditions can significantly influence signal behavior. While many factors play a…
Baluns, ununs, and chokes play a critical role in antenna systems, particularly when ensuring efficient power transfer and minimizing interference. Though simple in appearance, these components influence everything from feedline…
The Siglent Technologies SDS1104X-E 100MHz Digital Oscilloscope is a standout device in the world of test and measurement instruments. With four analog channels and a broad feature set, this oscilloscope…
The fundamentals of wire antennas form the backbone of amateur radio setups due to their simplicity, effectiveness, and affordability. They function by radiating and receiving electromagnetic energy, primarily across HF…
Manufacturers build 10 meter radios as full-featured ham transceivers that operate within the 28 to 29.7 MHz band. These radios incorporate a transmitter, a receiver, and the bandpass and audio…
Certain dual-band amateur radios feature a powerful function called cross band repeat. Particularly mobile transceivers. It allows the radio to receive on one band (usually UHF or VHF) and automatically…
Single Sideband, or SSB, is a highly efficient form of amplitude modulation widely used in amateur radio, marine communication, and aviation. While AM transmits a carrier and two identical sidebands,…
