Demonstrates the online presence of the West Island Amateur Radio Club (WIARC), a Canadian amateur radio organization. The resource presents fundamental club information, including contact details via an "info" email address. It also indicates the club's location within Quebec, Canada, and its focus on **ham radio** activities. The site's technical implementation notes its creation with **Arachnophilia 4.0**, a specific HTML editor. This resource, while minimal in content, serves as a digital point of contact for the WIARC. It confirms the club's existence and provides a channel for inquiries, which is typical for many local amateur radio clubs. The mention of a frame-compliant browser suggests an older web design, common for sites maintained over several years.

Low-frequency (LF) radio time signals, operating primarily in the 40–80 kHz range, are broadcast by national physics laboratories for precise clock synchronization. Transmitters like **JJY** (40 kHz, 50 kW; 60 kHz, 50 kW), RTZ (50 kHz, 10 kW ERP), MSF (60 kHz, 15 kW ERP), WWVB (60 kHz, 50 kW ERP), RBU (66.66 kHz, 10 kW), and DCF77 (77.5 kHz, 50 kW) cover vast geographic areas, often several hundred to thousands of kilometers. LF signals offer distinct propagation advantages over higher-band transmissions such as GPS. Their long wavelengths (3–6 km) enable effective diffraction around obstacles like mountains and buildings. The ionosphere and ground act as a waveguide, eliminating the need for line-of-sight and allowing a single powerful station to cover extensive regions. Ground wave propagation minimizes ionospheric variability effects on transmission delay, and signals penetrate most building walls effectively. Robust and low-cost receivers, often priced at 20–30 USD/EUR, are widely used in radio clocks. These receivers typically comprise a tuned ferrite core antenna, a receiver IC (e.g., Atmel T4227, U4223B, MAS1016) for amplification and AM detection, and a microcontroller for decoding the time signal and phase-locking a local clock. Specific components for DCF77, MSF, and WWVB are readily available from vendors like HKW Elektronik and Ultralink.
