THEORY OF OPERATION

4.1

GENERAL

This manual covers KX 165A configurations.

4.1.1

KX 165A FEATURES

The KX 165A is a single unit, panel mounted communication transceiver/navigation receiver with
glideslope receiver and VOR/LOC Converter. The functional capabilities are:

A.

A microprocessor controlled communication transceiver which operates from 118.00
MHz to 136.975 MHz in 8.33 kHz increments providing 2280 channels. 32 program-
mable memories.

B.

A microprocessor controlled navigation receiver for VOR/LOC signals from
108.00MHz to 117.95MHz in 50kHz increments providing 200 channels.

C.

A microprocessor controlled glideslope receiver operating from 329.15 MHz to
335.00 MHz in 150kHz increments for 40 glideslope channels.

D.

A microprocessor controlled VOR/LOC converter capable of calculating and display-
ing bearing VOR radial digitally.

E.

A microprocessor controlled VOR/LOC converter I/O board for use with indicators
that do not contain an internal converter.

F.

DME Channeling

1.

Provides data to interface with KN 62/A/64 DME or the KDI 572/574 or KPI
553A indicator which will in turn control the KN 63 DME or the KDM 706
DME.

2.

Provide data to interface with KA 120 Adapter which will in turn channel 2
x 5 or slip code DME’s.

G.

Digital Display of:

1.

Communication “USE” and “STANDBY” frequencies.

2.

Navigation “USE and “STANDBY” frequencies.

3.

VOR Radial information displayed in navigation “STANDBY” window.

4.

Internal course deviation indicator for VOR and localizer.

5.

Elapsed timer: countdown and elapsed time.

H.

Navigation and Communication frequency information is stored in a non-volatile
memory. Information is stored when the radio is turned off and will re-channel to the
same frequencies when turned on.

I.

Front panel lighting of bezel and knobs.
