    • High Q electronically tunable filter in 470-798 MHz
    • 1st narrowband filter
    • 2nd narrowband filter
  • Wideband and Narrowband DSP-FM operation (SW selectable):
    • Narrowband allows more 50% band efficiency
    • Narrowband allows about 3dB extra sensitivity and noise immunity
  • Extreme low noise VCO with ultrafast spectrum scan for optimal quick & easy setup
  • High contrast OLED display
  • Automatic scan & transmitter programming through infrared and Bluetooth 5 long range
  • DSP based for extreme flexibility and multi-companding operations
