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 ...

Building a High-Gain Cubical Quad Antenna for the 2-Meter Band: Tips, Formulas, Pros, and Cons

-
Image
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...

In recent years, digital voice communication has become more accessible than ever before. Digital communication is popular because it offers better sound quality, longer range, and more reliable connections. The MMDVM hotspot is one of the devices that have revolutionized digital voice communication. In this blog post, we will take a closer look at what the MMDVM hotspot is, its benefits, how it works, and how to set it up. What is an MMDVM hotspot? The MMDVM hotspot is a small, low-cost device that allows users to connect to digital voice networks using a handheld radio or mobile device. It acts as a hotspot, similar to how Wi-Fi hotspots work, and allows users to connect to digital voice networks from anywhere with an internet connection. The MMDVM hotspot can be used with popular digital voice communication protocols like DMR, D-Star, and Fusion. Benefits of Using an MMDVM Hotspot The MMDVM hotspot offers several benefits for users, including: Increased Range: The MMDVM hotspot can ...
