Software-Defined Radio (SDR) technology has revolutionized the way of approaching radio communication systems by enabling the flexible and versatile manipulation of radio signals in software. Present work focuses on development of low-cost SDR receiver with a Python-based Graphical User Interface (GUI) to provide a user-friendly platform for controlling, visualizing, and interacting with SDR operations. The receiver involves use of Raspberry pi 4 hardware device to serve as an underlying software architecture along with several hardware components like ADC and DAC converters and a power amplifier to improve Tx/Rx signal strength and subsequentially the building blocks of a radio transmitter has been implemented through a portable and handy setup operation in Fm range 88-108 MHz effectively.
