Okay, from what I have been reading, and what your only saying, the standard DES in the NX-5000 will talk to any other radio with DES,
the right CKR and the right ID, has to be the same, as I have tested this with my NX-5700 and TK-5720 demo radio.
(which I have AES-DES KWD-AE21K) and the two talk encrypted in P25 mode. (I use the KPG-113AE to program it)
If your using a KVL-4000 then the external modules (3 types) should work.
I can't tailor this reply to specifics but you should be able to get the kenwood dealer your talking to
or their Manufacturer's rep to come up with a demo radio.
If you need more information, you can contact me privately by my gmail and I will see what I can get
for you.
Here is a quick brief on it
