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.
