Bandwidth On analog mode, there are two types of bandwidth available, you can choose bandwidth as wide (25 KHz) or narrow (12.5 kHz) via programming software. Via programmable software to set it: Channel folder Zone An analog channel Bandwidth CTCSS/CDCSS On analog channel and digital analog compatible channel, you can set unique CTCSS/CDCSS to guarantee the privacy of your communication, on digital compatible analog or analog compatible digital channel there must have a CTCSS/CDCSS. If CTCSS/CDCSS has been set on the current channel, CTCSS/CDCSS match is required for the radio to receive an incoming signal. You can select a CTCSS/CDCSS from CTCSS frequency table or CDCSS code table, or input non-standard CTCSS/CDCSS manually. Via programmable software to set it: Channels folder Zone An analog channel TX Parameters to select encode RX Parameters to select decode Decode: Only when receiver receives a call containing matching the decode, you can hear the call;

Encode: Signal that you transmit will only be heard by parties whose 35 CTCSS/CDCSS signaling matches your radios. Note The radio approve of non-standard code, on analog mode, you can input non-standard code manually as you need. CTCSS Standard Frequency Table CTCSS Freq. CTCSS Freq. CTCSS Freq. CTCSS Freq. No.
