Nexedge Code

[ki4gyw]

Do the Kenwood Nexedge radios have the 16 bit security code in conventional?

[trashman43]

in analog mode it is simple voice inversion, same as on the tk-2180 and tk-7180

ncryption (Conventional Group) From help file---



Encryption allows you to enable or disable the Encryption. If this function is enabled, the transceiver will encrypt the data for communication when the transceiver communicates using digital audio and digital data.
Range:

Check (Enable):

Enables the Encryption.

Uncheck (Disable):

Disables the Encryption.

Default:

Unchecked (Disabled)

Note:

• Encryption cannot be configured if "Analog" is selected from the Channel Type dropdown list.
• Encryption cannot be configured if no data is configured in the Key Data edit box in the Encryption window.
• Pressing the Scrambler/Encryption key or selecting "SCRAM/ENCRYP" after pressing Menu key will toggle the Encryption between enabled and disabled.
• If "Type 2" is selected from the Encryption Type dropdown list in the Encryption window and if Encryption is disabled by clicking off the Encryption checkbox, the speaker in the transceiver remains muted and does not emit the received audio upon receipt of the encrypted signal.
• This function can be configured for a transceiver having firmware version 1.19 or later.

Available Models with this Function

Model Name Availability of this Function NX-200/ NX-210/ NX-300 V NX-700/ NX-700H
NX-800/ NX-800H V

Not talking about the scrambler! there is some type of key to keep pirates off the repeaters supposly, what I am wanting to know is if the key exist on the digital conventional side. what I am wanting to figure out is if its possible to do the " Digital Voice Conversion Method" with nexedge Digital Voice Conversion Method - The RadioReference Wiki

The 16-bit key is for the digital encryption built into the NEXEDGE system. It works in NEXEDGE conventional and trunked systems. NEXEDGE has clear and encrypted operation, similar to P25 clear and encrypted modes. The built-in encryption algorithm is the 16-bit digital equivalent of analog voice inversion scrambling. It's nowhere near as secure as AES or DES encryption but more than good enough for most uses. The possible encryption key values are 1 thru 32767 inclusive. For NEXEDGE users requiring stronger encryption and have money to burn, AES and/or DES options exist.

The "codes" I think you're referring to in order to control access are RAN codes. RAN = Radio Access Number. It's the NEXEDGE digital equivalent of CTCSS/PL and DCS/DPL in analog radio systems and NAC (network access code) in P25 systems. RAN values are numbered 0-63, where 0=OFF (equivalent to digital CSQ) and 1 thru 63 are RAN values. Selecting a RAN value to use is equivalent to selecting a CTCSS/PL tone or DCS/DPL code in an analog system.

Don't bother with the Digital Voice Conversion Method trick...it won't work. NEXEDGE is NOT P25 at all. It is NXDN. Icom's iDAS (Icom Digital Advanced System) is also NXDN. NEXEDGE has 12.5kHz and 6.25kHz modes. iDAS is 6.25kHz only. NEXEDGE and iDAS are compatible with each other in 6.25kHz bandwidth mode only. Icom and Kenwood jointly developed the NXDN digital standard. They are compatible in conventional systems in 6.25k mode only but differ in trunking systems. Icom and Kenwood each did their own thing with trunking.

There is currently no digital scanner on the market that can decode NXDN. It's NOT P25. Maybe we might see a NXDN-capable scanner in a few years after the NXDN market develops and there's enough market demand for a NXDN scanner.
