Implementación de una estación de radioaficionados en las instalaciones de la carrera de telecomunicaciones de la Espoch en la banda HF y VHF.

Abstract

The present graduation project aimed to implement an amateur radio station within the Telecommunications department facilities at ESPOCH, intended to operate on HF and VHF bands. Initially, analyzing the national regulations regarding frequency allocation was conducted in collaboration with Zonal Coordination 3 of ARCOTEL. A thorough examination of amateur radio station operations was undertaken, followed by a technical study. Implementation began implementing a Software Defined Radio (SDR)-based transceiver using GNU RADIO. The radiating system was designed using amateur radio simulation software, and three strategic antennas were selected: a Delta Loop and a Dipole for HF, as well as a Quad-Cube antenna for VHF. An amplification stage was incorporated through module integration to enhance system operation. HF coverage tests were conducted at three points over distances exceeding 5 km using a mobile system, while VHF tests covered local scenarios with and without a direct line of sight. Among the achievements, establishing an Amateur Radio Club constituted legally within the institution and providing a workspace for the station was highlighted.
