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).

**APRS TX I-Gate with APRX and the Universal Radio Controller** This project explores the creation of an APRS TX I-Gate to improve message delivery in amateur radio communications. Initial experiments involved configuring a picoAPRS v4 and later a G1LRO Universal Radio Controller (URC) with a Quansheng UV-K5 as digipeaters. While both setups successfully retransmitted signals, they failed to receive incoming APRS messages. To address this, a Raspberry Pi Zero running Debian and APRX-2.9 was repurposed to provide network connectivity, transforming the URC into an effective TX I-Gate for seamless APRS message handling.
