Best NXDN Simulcast System Scanner available?

Correct. Firmware allows an encryption key to be added in the custom firmware. That can benefit anyone with a scanner that has proper authorization to use a key. But it seems limited to certain types of enc and pretty sure it only works with a static key.

Unication also allows enc support on some models and as of 2022 it was limited to AES, DES (Phase 1 only), URC4 (ARC4, ADP)

Makes sense. The notion that a $750 consumer-grade scanner could crack key codes seemed ridiculous.

From my very limited knowledge of Enc, it seems you would be right about the static key. A constantly changing key would require entering a new key for every transmission. That would be impractical, at best.
