Basically, I love this fantastic radio! It's due to a lot of strong sides.

Both mobiles and portables

  • Affordable pricing of radios as such (but not software options and accessories)
  • 3 digital standards supported (but 2 only at the same time): NEXEDGE, P25 and DMR
  • Three-mode mixed mode: analog + 2 digital standards at the same time
  • APCO25 9600 Trunking and Phase II support
  • Really big and cool full-color LCD
  • Well-constructed and feel solid
  • Good sensitivity (actually measured values are in -120...123 dBm range)
  • Huge channel capacity (1,024; up to 4,000 with correspondent paid option)
  • Virtually unlimited scan list depth (depends on memory structure chosen)
  • microSD cards support for audio RX/TX recordings (audio can be accessed via USB)
  • Not bad RF immunity and intermodulation (better than any Icom, most of Vertex-Standard and comparable to Motorola radios)
  • Wide UHF-L split that covers 90 MHz: from 380 to 470 MHz
  • Good TX audio in digital modes (but not analog)
  • Built-in Bluetooth and GPS receiver (Bluetooth requires paid software option for serial comms and data applications)
  • Motorola KVL support
  • Wideband (25 kHz) option for FCC approved users
  • MDC-1200 support out of box
  • Free 56-bit DES encryption built-in (no hardware option board required)
  • Optional 40-bit RC4 encryption for DMR mode (fully compatible with Motorola Enhanced Privacy
  • Optional 256-bit encryption (requires hardware plugin module)
  • Programmable frequency inversion scrambler with 1 Hz step and "multikey"; "Keys" can be assigned to channels.
  • DMR Auto Slot Selection (similar to Hytera pseudo-trunking)
  • Many programmable keys - enough for any use case
  • Really high IP ratings: IP67/68

Portables only

  • FPP availability for FKP and LKP radios
  • Standard 2-pole SMA connector, but not something 1-pole or proprietary
  • Smart batteries and charger availability (similar to Motorola IMPRES technology)
  • The same accessory connector as for 12+ years: from TK-x80 to NX5000

Mobiles only

  • One or multiple heads to multiple RF decks configurations support. Setup can be dual-band or even triple-band. For mobiles only of course.
  • Dual microphone system for effective noise-cancelling
  • Illumination sensor to change display backlight depending on the lighting
  • Standard RJ-45 mic connector instead of something proprietary

In general, this is all, if you do not go into too much detail. As you can see, JVCKENWOOD company managed to create a truly unique product, which does not have 100% equivalents on the market.
