The site also features a comprehensive list of N4GN's recommended ham radio web picks, covering various categories like contesting resources, DXing, VHF/UHF/Microwave, and propagation information. The KCG's map center coordinates were updated on May 16, 2015, shifting approximately 16.5 miles SSW to 37° 21' N, 85° 39' W. Despite acknowledging current inactivity and an outdated web presence, the group remains operational, exploring options for reorganization, including a potential merger with the Tennessee Contest Group (TCG), which was ultimately rejected. The site emphasizes that membership applications are considered from anyone with a genuine interest in contesting.

The Southeastern VHF Society (SVHFS) is a not-for-profit organization incorporated to promote amateur radio operation on the bands above 50 MHz in the southeastern United States.

Monitoring extremely weak signals in the QRSS (Very Slow Morse) mode requires specialized receiving and processing capabilities to extract information below the typical noise floor. This project provides a software solution, _QrssPiG_, designed to run on a Raspberry Pi, enabling it to function as a dedicated QRSS grabber. It interfaces with various Software Defined Radio (SDR) devices, including the popular _rtl-sdr_ dongles and _HackRF_ units, to acquire raw I/Q data streams. The software then performs the necessary signal processing to visualize and decode these faint, long-duration CW transmissions, often operating with milliwatts of power. The system leverages the computational power of the Raspberry Pi for real-time signal analysis, allowing hams to participate in QRSS experiments and monitor distant beacons. It supports different SDR hardware, offering flexibility in setup and deployment for home stations or remote monitoring sites. The project includes detailed instructions for installation and configuration, making it accessible for those familiar with Linux environments. This grabber is particularly useful for tracking propagation on the LF and HF bands where QRSS activity is common, providing a visual representation of signal presence over extended periods.
