JS8Call is an amateur radio software that enables operators to communicate with each other over the airwaves using a digital mode called JS8. This mode is based on the popular FT8 protocol but extends its capabilities to allow for more interactive and message-based communication, rather than just exchanging call signs and signal reports. Here's a breakdown of what JS8Call offers: 1. Weak Signal Communication: Like FT8, JS8Call is designed to work well even when signal conditions are poor, allowing for reliable communication over long distances. 2. Message-Based Interaction: Unlike FT8, which is primarily for making contacts and exchanging basic information, JS8Call allows for longer, free-form text messages, making it more suitable for actual conversations. 3. Networking Features: JS8Call includes features such as relaying messages, storing and forwarding messages, and calling specific stations, which can be especially useful in emergency communication scenarios or when trying to reach a particular station. 4. Frequency Agility: JS8Call allows operators to use different frequencies for communication, making it adaptable to band conditions and regulations. 5. Error Correction: It uses strong error correction techniques to ensure messages are received accurately even in challenging conditions. JS8Call is popular among amateur radio enthusiasts who are interested in digital modes of communication, especially in scenarios where robustness and reliability are important, such as emergency communications or remote area communications where traditional internet or phone services are not available. https://youtu.be/PV-BNN3adxU
