Demonstrates _FreeDV RADE_, an open-source digital voice mode for HF, which combines machine learning with classical Digital Signal Processing (DSP) to achieve improved speech quality and spectral efficiency. Released in June 2025 by ARDC grantee FreeDV, RADE operates at Signal-to-Noise Ratios (SNRs) as low as -2 dB and occupies approximately 1.5 kHz of bandwidth, half that of a typical SSB signal, while transmitting about 8 kHz of voice audio. The mode also features an optimized Peak-to-Average Power Ratio (PAPR) for efficient power amplifier use, reducing heat and consumption. Users, such as _VK3TPM_, report significantly improved listening ease compared to analog modes, particularly in high HF noise environments, making it easier to conduct nets across various Australian states. The mode's integration into popular radios like the _FlexRadio 6000_ series allows direct operation without external computers. A C library for RADE is available, facilitating broader integration into other radios and SDR programs, with development continuing on FreeDV RADE v2 to further narrow bandwidth below 1 kHz.

The author discusses ways to display VHF and higher bands using a K3/10 as  transverter, NooElec Upconverter, SDR, and SDR-Console. He observed that the results were remarkable, with the tuned frequency visible at +/-100kHz. The K3 Interface Option (KXV3A) produces a buffered IF output at 8.213MHz, which is received using a NooElec NESDR SMArt SDR dongle and Ham It UP Upconverter. The SDR-Console program is utilized, with Omnirig synchronizing the SDR and K3. To configure the system, particular parameters are required, such as adjusting the IF frequency to 133.213MHz (125MHz + IF frequency) and inverting the spectrum. The Panadapter demonstrated ES activity at 10m, and modest software tweaks may be required for improved performance.

Manages log consistency across multiple digital mode applications, specifically addressing the common issue of log divergence between _MSHV_ and _WSJT-X_ for FT8, FT4, and other weak-signal modes. This prevents duplicate contacts and ensures accurate DX tracking when using both programs. The utility computes a deduplicated union of entries from both `_mshvlog.edim` and `_wsjtx.log` files, then updates each log with missing QSOs. It supports a deduplication key based on callsign, date, time (to the minute), band (derived from frequency), and mode. The tool is available as a standalone Windows executable or a Python version requiring Python 3 with _Tkinter_. Users select log folders, close both applications, and initiate the 'Merge' function. The process includes automatic timestamped backups of log files before any modifications, safeguarding QSO data.

Over 44,000 square kilometers of Scotland's natural beauty provide a unique backdrop for the _GMFF_ award program. Designed for amateur radio operators who thrive on portable operations, this program encourages activators to set up stations in designated flora and fauna areas. Participants engage in _SSB_ and _CW_ modes, making contacts from these scenic locations, which are part of the _WorldWide Flora and Fauna_ network. Activators and chasers alike benefit from the program's structure, which awards points for successful contacts. The _GMFF_ program is part of a larger global initiative, allowing operators to contribute to conservation awareness while enjoying their hobby. With a focus on environmental preservation, the program aligns amateur radio activities with ecological interests, promoting responsible and sustainable operating practices. The program's website provides resources for participants, including maps of designated areas and guidelines for operation. By participating, operators not only enjoy the challenge of portable operation but also support the conservation of natural habitats. The _GMFF_ program thus combines the thrill of amateur radio with a commitment to environmental stewardship.

The State QSO Party Challenge is an annual program recognizing amateur radio operators' participation in U.S. State and Canadian Province QSO parties. To qualify for the SQP Challenge, participants must make at least two QSOs in a minimum of two SQP Approved QP contests and submit their scores to 3830Scores.com. The site details the SQP Mobile/Portable Challenge, an overlay competition encouraging mobile/portable operations, with scoring identical to the main SQP Challenge: (Number of QPs entered) x (Number of QSOs) = Score. Eligibility for the Mobile/Portable Challenge requires prior qualification for the SQP Challenge. The website also mentions a State QSO Party Club Challenge and provides contact information for questions. The 2026 SQP Challenge will be dedicated to Stan Zawrotny, K4SBZ, a key team member instrumental in the program's development. Participants are recognized for reaching five levels of achievement: Bronze, Silver, Gold, Platinum, and Diamond. Scores are calculated by totaling reported contacts and multiplying by the number of SQPs entered year-to-date, encouraging more entries and longer operating times. The Worked All QSO Parties (WAQP) program, sponsored by Icom America, offers certificates for participating in at least 50% of approved contests, with a goal of participating in all. WAQP requires submitting a log with at least two valid contacts to the contest manager, in addition to the 3830scores.com submission.
