NXDN
NXDN™ is a proprietary narrowband digital protocol developed by ICOM Inc. and JVC KENVOOD Co. to
provide a low complexity digital radio protocol solution which satisfies the FCC narrowbanding mandate.

Frequency range VHF/UHF
Operation modes Digital voice and data system
Modulation 4-level FSK
Vocoder AMBE+2™
Transmission Rate 4800 bps/9600 bps
Channel Spacing 6.25 kHz/12.5 kHz
Input format(s) IF
Optional Features Digital Scrambling, Encryption, Trunking Mode
The modulation type enables manufacturers to use existing analog FM designs with the addition of extra
components for digital capability. This provides backwards compatibility with the analog systems and re-
duces the complexity of development.
To use the mode set Offset to the IF output of the receiver. The current version implements the decoding
of voice and data. When a call occurs, some status messages are displayed in the text output. Data
transmissions are displayed as a hex dump of the decoded data. The parameter Confidence shows the
demodulation quality.
When a call is encrypted, the voice output is muted, but status messages are displayed. When encrypted
data is received, it is shown on the screen in encrypted form. Usually, it is shown in red, because the data
checksum can not be verified with encrypted data.
OLIVIA
Olivia is a mode developed by Pavel Jalocha, who, among other modes, developed the basics of PSK31. He
named this mode after his daughter.
