JS8Call is a digital mode software designed for amateur radio operators to facilitate keyboard-to-keyboard communication, particularly under weak signal conditions. It uses the JS8 modulation, a derivative of FT8, to enable robust, low-power, long-distance messaging on HF bands. Key uses include:

• Conversational QSOs: Unlike FT8’s automated signal exchanges, JS8Call supports free-text, real-time chats, allowing operators to have meaningful conversations.
• Weak Signal Communication: It can decode signals as low as -24dB to -28dB, making it ideal for low-power (QRP) or challenging propagation conditions.
• Message Relaying: Features like automatic Heartbeat (HB) transmissions and store-and-forward messaging allow stations to relay messages through other operators, extending communication range.
• APRS Integration: JS8Call can send messages and position reports to the Automatic Packet Reporting System (APRS) network via stations with internet access.
• Emergency and Exercise Communications: Its messaging capabilities, including acknowledgments (ACKs), are useful for reliable communication during emergencies or drills, especially in areas with limited infrastructure.

JS8Spotter is a companion software for JS8Call, designed to enhance its functionality for amateur radio operators. It serves as a utility tool to fill gaps in JS8Call’s feature set, offering the following key uses:

• Search Term Traffic Scanner: JS8Spotter’s primary function is to monitor and filter JS8Call band activity based on user-defined search terms. It helps operators track specific callsigns, keywords, or topics in the Band Activity pane, saving and exporting relevant data for later review. This is useful for staying informed about specific stations or conversations without manually sifting through all activity.
• APRS Messaging: It simplifies sending APRS (Automatic Packet Reporting System) messages, such as SMS, email, grid location, or POTAGW (Position, Object, Tactical, Group, Weather), by providing a user-friendly interface that eliminates the need to memorize complex syntax.
• Offline Mapping: JS8Spotter includes a basic offline map that displays grid coordinates gathered from band activity, helping operators visualize the locations of stations they’re monitoring or communicating with.
• Automated Responses: It allows users to set up custom automated responses for specific triggers in JS8Call, streamlining communication for repetitive tasks or acknowledgments.
• Multiple Choice Forms (MCForms): JS8Spotter supports a simplified form system called MCForms, enabling standardized, multiple-choice-based communication. These forms are not transmitted over the air but help structure messages for clarity, with optional free-text fields for additional details. This is particularly useful for emergency communications or structured data exchange.
  

Fldigi is a software application used primarily by amateur radio operators (ham radio enthusiasts) for digital communication. It enables the transmission and reception of various digital modes, such as Morse code (CW), PSK31, RTTY, Olivia, and others, over radio frequencies. Key uses include:

• Digital Mode Communication: Facilitates text-based communication using digital signals, often more reliable than voice in weak signal conditions.
• Signal Decoding and Encoding: Converts digital signals to text and vice versa, supporting modes for different bandwidths and noise resilience.
• Contesting and DXing: Used in ham radio contests and long-distance (DX) communication to log contacts and exchange information.
• Emergency Communications: Employed in disaster response for reliable data transmission when other systems fail.
• Experimentation: Allows hobbyists to test and develop new digital modes or interfaces with radios.
• HTML Forms: Place HTML forms in your /home/YOUR_USERNAME/.nbems/CUSTOM folder (Linux path). After installing the HTML form, close then restart FLMSG.
