OVERVIEW
The demo’s main objective is to show the IA4420’s capability to monitor multiple frequencies, receive data from an FSK transmitter, and then
The Repeater Demo has three main components: the IA4420, which is the system radio, a C8051F311 type 8051 microcontroller, which controls the application, and a 2 line 16 character LCD, which informs the user of the repeater status
(Note).
The current version of the Repeater Demo is equipped with a 50 Ohm SMA connector for the antenna.
