Programming software, diagrams, radio mods, secrets, service manuals for Motorola, Yaesu, Kenwood, Icom, Alinco. A large collection of ham radio equipment data also known as Ham.dmz.ro

A digital mode decoding and terminal program that uses no terminal unit, terminal node controller, or multimode hardware. It does all its decoding using the sound card inside the computer, and it can interface with a radio using a COM port. Zakanaka is an extremely cost-effective way of operating PSK31 and RTTY

How High should my Dipole be? Dipole Antennas and the effect of height above ground. The effectiveness of a dipole antenna is influenced by its height above ground, determined by the intended use such as DX work, local communication, directionality, omni-directionality, and feed point impedance. Through EZNEC modeling, the study evaluates a 40-meter dipole's performance at various heights, from 7 to 560 feet. Findings reveal that lower heights enhance omni-directional local communication, while higher placements favor DX work with low-angle radiation. The study emphasizes the importance of defining operational goals to optimize dipole height and performance.
