  • Built in IF discriminator data output can be enabled to the headphone jack and can be used with UniTrunker, Trunk88, and Treport decoders with a standard audio patch cord.
  • Built in discriminator data output in simple ASCII output using the PC/IF port can be sent to a com port or internal microSD card.
  • Tri-color alert LED - Object programmable; eight factory default colors to any color / brilliance you want by having direct access to the R-G-B drive values (including flash) to assign to talkgroups, frequencies, agencies, etc. Example settings are shown in the owners manual.
    • LATCH option; the color of the last received object stays on until reset.
  • Motorola Smartzone systems
    • Scanner option to look for the site with the best received CC decode rate.

(Not the same as RSSI on the Motorola rigs, but similar in operation.)

  • Scan Set; create a scan list tailored to your favorite scan list settings.

One button operation to get to this set.

  • Spectrum Sweeper Near field frequency capture
  • Triple conversion
  • Virtual Scanner Memory Management system (Second generation); One copy of working memory can hold virtual numer objects, meaning any combination of talkgroups, conventional channels, and trunking systems. Each V-Scanner II folder holds one copy of working memory. Actual memeory size is determined by the size of the microSD card memory size used.
  • Preprogrammed with all systems currently in the Radioreference database with ability to update as needed or once a week.

    • 2GB or smaller: FAT16, 32kB clusters
    • larger than 2GB: FAT32, 32kB clusters
  • Advanced encryption handling
    • EncMode selects how the radio treats encrypted voice calls. Simple Display must be unchecked.
    • “Noise” setting plays the random undecoded encryption noise. Simple Display must be unchecked.
    • “Silent” setting plays no audio during the call. Simple Display must be unchecked.
    • “Tone” setting plays a soft tone for the duration of the call. Simple Display must be unchecked.
    • EncLevel selects the tone level for tones played during encrypted calls
  • Advanced conventional P25 systems
    • CONV TGID When enabled, shows the Talkgroup ID for P25 Conventional Talkgroup calls. Simple Display must be unchecked.
    • CONV Radio ID when enabled, shows the Radio ID for P25 conventional calls. Simple Display must be unchecked.
  • CTCSS/DCS/NAC Search with store via Menu key press during comm and the "S" search icon display when the object is programmed for search.
