FT8: The Revolutionary Digital Mode Transforming Amateur Radio M7ENP Amateur Radio Blog ``` FT8: The Revolutionary Digital Mode Transforming Amateur Radio TL;DR: FT8 is a weak-signal digital mode that has revolutionized amateur radio since 2017, enabling global contacts with low power and compromised antennas. It uses 15-second transmit/receive cycles and can decode signals 10-15 dB below the noise floor. What is FT8? FT8 stands for "Franke-Taylor design, 8-FSK modulation" - a digital weak signal communication protocol that has taken the amateur radio world by storm. Joe Taylor (K1JT) , a Nobel Prize laureate, and Steve Franke (K9AN) released this mode on June 29, 2017, and it rapidly became the most popular digital mode within just two years. FT8 is designed for making reliable contacts under challenging conditions including: Low solar activity periods ...

Introduction Cubical quad antennas have been a popular choice among amateur radio operators for many years, due to their relatively simple construction and high gain. This type of antenna is especially popular for use on the 2-meter band, as it can provide excellent performance with only a moderate-sized structure. In this blog post, we will discuss the construction of a 2-meter cubical quad antenna, including construction tips, formulas, and the potential pros and cons of using this type of antenna. What is a Cubical Quad Antenna? A cubical quad antenna is a type of directional antenna that consists of a square or rectangular loop of wire, supported by a framework of poles or wires. The loop is fed by a single coaxial cable at one corner, and the other three corners are connected to a set of elements called "directors" or "reflectors," depending on their location and function. The directors and reflectors are typically shorter or longer than the main loop, and thei...

The documentary "Ham Radio: The First Social Network" explores the history and appeal of this hobby, and sheds light on how it has evolved over the years. The documentary takes us on a journey through the history of ham radio, starting from the early days of wireless communication to the present day. We learn about the pioneers who made important contributions to the development of this hobby, such as Guglielmo Marconi, who is credited with inventing the first radio telegraph system in 1896. The documentary also explores the cultural and social impact of ham radio. It highlights how ham radio enthusiasts have used this technology to communicate with people from all over the world, forming a global community of like-minded individuals who share a common interest in communication and technology. The documentary also shows how ham radio has played a role in various important events throughout history, such as the Cuban Missile Crisis and the September 11th attacks. One of the mo...
