Understanding QRM vs QRN in Radio Communications Radio operators hear QRM vs QRN every day. However, not all interference comes from the same source. Some noise originates from human-made devices,…
Station ground vs electrical ground are often treated as the same thing, but they serve completely different purposes in a radio installation. Understanding how they differ — and how they…
What SWR vs Impedance Mean in Radio Systems Standing Wave Ratio, SWR vs Impedance describe how efficiently radio frequency energy moves from a transmitter into an antenna system. Although many…
Audio hum announces itself as a steady, low-frequency tone that never seems to move or fade. However, it usually signals a problem in the signal path rather than a failure…
AC Log from N3FJP is one of the most widely used amateur radio logging programs because it focuses on speed, simplicity, and practical station operation. Although many logging applications exist,…
The Yaesu FTDX 3000 is a full-featured HF and 50 MHz base station transceiver designed for operators who demand exceptional receiver performance, strong transmit capability, and advanced signal visualization. It…
The Yaesu FT-70D is a dual-band handheld transceiver designed for reliable analog and digital communication across VHF and UHF amateur bands. It combines durable construction, straightforward controls, and advanced digital…
The Astron RS-35A power supply is a linear regulated DC power supply designed to deliver stable, clean 13.8-volt output for radio equipment and other high-current electronics. It uses a traditional…
5 Military Radio Protocols ensure clean radio communications they prioritize clarity, speed, and reliability under pressure. However, many civilians never encounter this structured style. Therefore, learning core military radio protocols…
Ham radio microphone impedance describes how much the microphone resists the flow of audio signal current as it moves into the transmitter or audio processing chain. In practical terms, impedance…
