Yaesu Radio Router
This project is a communication router for the Yaesu station. It allows serial communication to four Yaesu radios from one RS232 port from the Computer. The ATMEL micro controller handles the communication between the PC and the radios and provides the RS232 to TTL conversion for the first generation PC controlled Yaesu radios. The station includes:
FT-736R – 144 MHz, 220 MHz, 440 MHz, and 1296 MHz transceiver
FT-737GX – HF and 50 MHz transceiver
FRG-8800 Receiver with VHF module
FRG-9600 VHF to 1 GHz Receiver
