WSJT-X implements communication protocols including FST4, FST4W, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, and Echo. These modes facilitate reliable, confirmed QSOs under extreme weak-signal conditions. JT4, JT9, and JT65 utilize a nearly identical message structure and source encoding, employing timed **60-second** transmit/receive sequences synchronized with UTC. JT4 and JT65 are designed for EME on VHF/UHF/microwave bands, while JT9 is optimized for MF and HF, offering **2 dB** greater sensitivity than JT65 with less than 10% of its bandwidth. Q65 provides submodes with varying T/R sequence lengths and tone spacings, suitable for EME, ionospheric scatter, and weak signal operations on VHF, UHF, and microwave. FT4 and FT8 operate with T/R cycles of 7.5 and 15 seconds, respectively, supporting enhanced message formats for nonstandard callsigns and contest operations. MSK144 is engineered for Meteor Scatter on VHF bands. FST4 and FST4W target LF and MF bands, achieving fundamental sensitivities near theoretical limits for information throughput; FST4 is for two-way QSOs, and FST4W for quasi-beacon WSPR-style transmissions, without requiring the strict time synchronization of protocols like _EbNaut_. WSPR mode enables propagation path probing via low-power transmissions, incorporating programmable band-hopping. The **WSJT-X 2.7** General Availability release introduces the QMAP program, Q65 Pileup, SuperFox mode, a Hamlib update option, and a Message System. SuperFox mode transmits simultaneously to up to 9 Hounds with a constant envelope waveform, providing approximately +10 dB system gain compared to older Fox-and-Hound operations. _WSJT-X 2.7_ for _Windows_ platforms includes _MAP65 3.0_, a wideband polarization-matching tool for EME. The **WSJT-X 3.0.0-rc1** candidate release represents a major revision with new features, some ported from _WSJT-X Improved_. This software is available for _Windows 7_ and later (32-bit/64-bit), various Linux distributions (Debian, Ubuntu, Fedora, RedHat, Raspberry Pi OS), and macOS (10.13 through 15).

Demonstrates BBLogger, a **freeware** logging application designed for both amateur radio operators and Short Wave Listeners (SWLs). Developed by IK2VIW, IZ2BKT, and IK2UVR, this software provides comprehensive station management capabilities, including **CAT control** for various transceivers, integration with digital mode software like WSJT-X, JTDX, and MSHV, and robust QSL management features. The application supports a wide array of functions such as DX cluster interfacing, mapping, awards tracking (including custom awards), and direct integration with services like LoTW, eQSL.cc, and ClubLog for QSL confirmations and OQRS requests. It also includes utilities for ADIF to CSV conversion and vice-versa, catering to diverse logging and data management needs. Recent updates, such as version 13.1, introduce a web server for log management from any device, allowing remote access and control. The software has improved ADIF import capabilities, including time settings for duplicate QSO detection, and enhanced filtering options for log searches. Performance improvements include faster automatic updates and manager database synchronization, along with optimized log checking at startup. Earlier versions added support for FT8 and FT4 modes, refined OQRS integration with ClubLog, and expanded QSL/label printing functionalities, enabling users to select specific callsign types (OM, SWL) for printing. The developers emphasize compatibility with Windows 10/11 for full functionality, noting limitations when running on older operating systems like Windows 7 due to modern security protocol requirements.
