Radio astronomy allows you to “see” the universe through radio frequencies rather than visible light. While professional observatories use massive arrays, an amateur radio telescope is surprisingly accessible
Getting started in amateur astronomy doesn’t require an observatory or thousands of dollars. In fact, many beginners make the mistake of buying a cheap, complicated telescope right away,
Amateur radio, commonly known as ham radio, is a popular hobby and voluntary public service that brings people, electronics, and communication together. It allows people to transmit voice,
A discone antenna is an exceptionally wideband, omnidirectional antenna that looks exactly like its name suggests: a flat metal disc mounted horizontally above a metal cone, separated by
Antenna polarization refers to the physical orientation of the radio wave’s electric field as it travels through space. When an alternating current flows through an antenna’s elements, it
HM207 Mic Cable of IC2730A Dual Bander is being visualized here, with two ends damaged and shield wire strands coming out. Next first step will be check continuity
The Moxon Rectangle (originally developed by Les Moxon, G6XN, and heavily popularized by L.B. Cebik, W4RNL) is a brilliant piece of antenna engineering. In simple terms, it takes
I have been discussing with many on air and online regarding the issue of connecting DVI-D external monitor to my FT-710 radio. I have been using a DVI-D
A Slinky dipole uses the helical steel coils of the classic toy to create a continuously loaded antenna, electrically lengthening the element while keeping its physical footprint very
