This study compares the reception performance of vertical and horizontal loop antennas on HF bands in a densely populated area. Using identical Wellgood active loop antennas and receivers, the experiment monitored FT8 signals over 24 hours. Vertical loops outperformed horizontal loops on higher bands (10m, 15m, 20m), while horizontal loops excelled on lower bands (30m, 40m, 160m), particularly in receiving long-distance (DX) signals. The horizontal loop's advantage on lower bands may be due to better low-angle performance and reduced sensitivity to man-made noise. Further research is needed to fully understand these differences and optimize antenna placement for various HF applications.

Paul McMahon presents a compact VSWR meter designed for QRP portable use, ideal for SOTA operations with rigs like the FT817. The device, constructed from readily available components, employs a simple resistive bridge for wideband performance from 1.8MHz to 52MHz, with diminishing accuracy at higher frequencies. Key features include no need for external power, simple calibration, and operation with low power levels. The design, detailed with parts lists, schematics, and construction guidelines, ensures a 2:1 worst-case VSWR to protect transceivers during antenna matching. Calibration points are set for accurate VSWR readings at various loads.

FT8 Live is a specialized web-based tool designed for the real-time graphical visualization of amateur radio propagation spots. Leveraging the data infrastructure of the PSK Reporter MQTT stream, the platform provides immediate situational awareness for radio operators. While the tool’s nomenclature references the dominant FT8 digital protocol, it offers broad compatibility, displaying spots from various other modes including CW, WSPR, and JT65. Distinct from the official PSK Reporter map, FT8 Live focuses exclusively on live data streams, eschewing historical archiving to prioritize current signal activity. A defining feature of the platform is its integration with the Summits on the Air (SOTA) API. This functionality facilitates "SOTA chasing" by automatically cross-referencing transmitting callsigns with SOTA alerts; a station is identified as an activator if the spot correlates with a scheduled alert within an eight-hour window. The tool represents a collaborative technical effort, featuring a user interface developed by Arron (ZL1AN), utilizing core data from Philip Gladstone (N1DQ), and stream delivery via Tom Stanton (M0LTE).
