KN 53
- 1.3" high flat-pack, NAV unit
- 200-channel navigation receiver
- Built-in 40 channel Glideslope receiver available as option (see table below)
- Features simultaneous gas discharge display of both active and standby frequencies
- Flip-flop frequency transfer button
- Electrically Alterable Read Only Memory (EAROM) provides non-volatile storage of two frequencies
- Used with either KI-203 or KI-208 VOR/LOC indicators and KI-204 or KI-209 VOR/LOC/GS converter/indicators
- Will operate an HSI such as KI-525A (of KCS-55A System) with a remote KN-72 VOR/LOC converter
- Output provided for automatic channeling of remote DME systems
- Composite VOR output signal provided to operate KI-229 RMI
- All solid-state system employs digital frequency synthesizer for NAV frequency control
- Microprocessor controls the display and provides DME tuning code conversion
- Crystal filter provides added protection against channeling interference for improved selectivity on 50 kHz frequencies
- Operates on any DC voltage from 11 to 33 volts
- Models available with diffused or non-diffused display lens, with 5V lighting and bezel removed for use in a system with a common bezel such as the CNI-5000 (see table below)
