	abstract = {We present a fully automated, deterministic technique for detecting and characterizing Large Scale Traveling Ionospheric Disturbances (LSTIDs) using 14 MHz amateur (ham) radio data. The method isolates wave periods between 1{\textendash}5 hours and applies sinusoidal curve fitting to the first-hop skip-distance edge of observed communication ranges, yielding quantitative estimates of LSTID amplitude and period. Data from the Weak Signal Propagation Reporting Network (WSPRNet), the Reverse Beacon Network (RBN), and PSKReporter, which is now merged and available on the CEDAR Madrigal database, were used produce a unified multi-year climatology of LSTID activity over the continental United States (2016{\textendash}2023). Results show clear seasonal patterns: enhanced LSTID occurrence during winter, weaker activity in spring and fall, and modest summer increases. These results are consistent with prior studies and suggest modulation by neutral wind filtering, sudden stratospheric warming (SSW), vertical coupling, and solar activity.},

	abstract = {<p>The Grape 2 is a three-channel radio receiver and an integral component of the broader Personal Space Weather Station (PSWS) project. The PSWS network is a distributed array of radio receivers designed to continuously monitor changes in the Earth{\textquoteright}s ionosphere. It achieves this by tracking frequency standard stations, such as WWV, WWVH, and CHU, on a 24/7 basis. The system includes software tools for control and monitoring. Each Grape station transmits daily data to a centralized, publicly accessible database hosted by the University of Alabama, where automated processing generates spectrograms. These visualizations provide researchers with rapid insights into ionospheric conditions and enable long-term studies of space weather phenomena.\&nbsp;</p>
