• Changing the memo ch the ic 735 sends out the following data automatically 132
• During transceive operation db3 must be on the ic 735 comes factory preset for 1200 baud and the network address is 4 also available are 300 and 9600 baud each receiver connected to the icom cl v system requires its own unique address in the same way that individual houses have different addresses 132
• Example the example frequency is 14 23 5mhz 132
• Factory setting and standard cl v baud rate 132
• Frequency is changed by using the main dial the microphone up down function vfo a b or by 132
• I______________i 132
• T ransceive 132
• The baud rate can be selected by using db4 and db5 refer to the chart at left 132
• The ic 735 has the capability to handle the x 10mhz digit 132
• Through the x 10hz digit the display shows all digits except 10hz the 1hz digit is dummy data 132
