KR-87

ADF Receiver/Indicator/Antenna System

Part No:

Manufacturer: BENDIXKING

The KR 87 maintains its reputation for offering superb dependability. This compact TSO'd unit gives you accurate bearing-to-station in the 200 kHz to 1799 kHz frequency range, complete with ADF, ANT and BFO tuning modes, plus audio output for station identification and monitoring AM broadcasts.

This compact TSO'd unit gives you accurate bearing-to-station in the 200kHz to 1799kHz frequency range, complete with ADF, ANT and BFO tuning modes, plus audio output for station identification and monitoring AM broadcasts. The KR 87's advanced coherent detection design rejects unwanted frequency noise and achieves much greater range while remaining less susceptible to engine noise, static and atmospheric interference. Its flip-flop frequency display allows you to switch between pre-selected standby and active frequencies with the touch of a button.

Both frequencies are stored in a non-volatile memory circuit, meaning you don't have to worry about battery power.
 
System priced as Silver Crown Plus ADF with slaved KI 228 Indicator system.

FEATURES

  • Digitally tuned solid state automatic direction finder which provides bearing information to stations in the frequency range of 200 KHz to 1799 KHz and which also provides audio reception to enable pilot to identify stations
  • Used with KA-44B combined loop/sense low profile ADF antenna OR KA-44 blade antenna
  • Automatic dimming circuit adjusts the brightness of the display to compensate for changes in the ambient light level
  • Coherent detection design rejects unwanted frequency interference, achieves significantly greater range and has less suspectiblility to engine noise, static and atmospheric interference
  • Can be interfaced with other 3-wire RMI indicators by way of KDA-692 RMI adapter
  • Models available with single or dual indicator driving capability (see table below)
  • Models available for 28 volt use only (see table below)
  • Can be used with single needle KI-227 ADF indicator or dual needle KI-228 indicator (both indiactors available with manual or slaved compass cards)
  • May be interfaced to King KI-229 or KNI-582 RMIs
  • Models available with ADF Superflag output for use with EFIS systems (see table below)
  • Internal timer for flight time and elapsed time which proves valuable for non-precision timed approaches, fuel management, dead reckoning navigation
  • Flip-flop frequency display allows to switch between pre-selected "standby" and "active" frequencies
  • Operates on any voltage from 11-33 VDC with 12 watts power consumption
  • Models available with 5 volt display lamps (see table below)
  • Models available with standard or shiny display lens (see table below)
  • Models available with clear or blue display light (see table below)
  • Models available with backlit nomenclature (see table below)
  • Forced air cooling not required
  • TSO'd
