GENERAL INFORMATION

1.1 INTRODUCTION

This manual contains information relative to the physical, mechanical, and electrical characteristics of
the King Radio Corporation Silver Crown KY 196/196E/197/197E 720 channel VHF communications transceivers.
Installation and operating procedures are also included. Information relative to t"e

maintenance,

alignment, and procurement of replacement parts may be found in KY 196/196E/197/197E Maintenance/Overhaul
Manual.

The units covered are as follows:

NOTE

All KY 196/196E RADIOS ARE 27.5 VDC, All KY 197/197E RADIOS ARE

13.75 VDC.

The KY 196/196E/197/197E transceiver is a TSO'd 720 channel communications transceiver and is desiqned to

provide two-w::lYvoice communication within the frequency range of

11~.OOOMHz

to B,).975MHz in ~5KHz

increments.

The KY 196/196E/197/197E is a panel mounted unit. Connections to the unit are made throuqh a 20 pin
Molex printed circuit board edge connector and a BNC coax connector at the rear of t"e unit.

ElectricaLLy, the KY 196/196E/197/197E consists of four sections: receiver, transmitter, frequency
synthesizer, and gas-discharge display circuitry. The only difference between the KY 196/197 and I<Y
196E/197E lies in their selectivity specifications (see Section 1.3). The only difference between the KY
196/196E and KY 197/197E is thei r rated t ransmi tter power out out and power requi r~ments (see Secti on

1.3) .

The KY 196/196E (-aS, -06, -07) and the KY 197/197E (-OS, -06) "ave the capability of oreproqra~minq UP
to nine memory channel frequencies for later recall. Channel frequency information is stored in ::I

non-volatile earom memory so that when the radio is turned off and then back on, channel information is
retained.

The KY 196/196E (-10, -11, -12) and the KY 197/197E (-10, -11) have the capability of remote transfer of
use and standby frequencies and the remote recall of channel frequency information.

2.1 GENERAL

SECTION II

INSTALLATION

This section contains suggestions and fa~tors to consider before installing the KY 196/196E/197/197E.

Close adherence to these suggestions will 1assure a more satisfactory performance from the equipment.

2.2 UNPACKING AND INSPECTING EQUIPMENT

Exercise extreme care when unpacking the unit. Make a visual inspection of the unit for evidence of
damage incurred during shipment. If a claim for damage is to be made, save the shipping container to
substantiate the claim. The claim should be promptly filed with the transportation company. It would he
advisable to retain the container and packaging material after all equipment has been removed in the
event that equipment storage or reshipment should become necessary.

2.3 EQUIPMENT INSTAlLATION

The KY 196/196E/197/197E installation will conform to standards designated by the customer, installing
agency and existing conditions as to the unit location and type of installation. However, the following

suggestions should be considered before installing your KY 196/196E/197/197E. The installing agency will

supply and fabricate all external cables. The connectors required are supplien by King Radio.

2.3.1 AVIONICS COOLING REQUIREMENTS

FOR PANEL MOUNTED

EQUIPMENT

The greatest single contributor to increased reliability of all modern day avionics is to limit the

maximum operating temperature of the individual units. While modern day individual circuit descdns

consume much less electrical energy, the watts per cubic inch dissipated within avionics units remains

much the same due to. high density packaging techniques utilized. Consequently, the imoortance of
providing avionics stack cooling is still with us.

While each individual unit may not reguire forced air cooling, the combined heat load of several units
operating in a typical avionics stack will significantly degrade the reliability of the avionics if
provisions for stack cooling are not incorporated in the initial installation. Recommendations on stack
cooling are contained in King Radio Installation Bullentin #55. Failure to provide stack cooling will

certainly lead to increased avionics maintenance costs and may void the King warranty.

2.3.2 Mounting Rack Installation

A. The KY 196/196E/197/197E is mounted rigidly in the aircraft panel. Select a position in the

panel that is not too close to any high external heat source. Remember to allow adequate

space for installation of cables and connectors. Avoid sharp bends and placing the cables too

near the aircraft control cables.

B. When installing two or more panel mounted units in a stack, the mounting trays shall be spaced

.050 inches (.127 cm) apart. Newer style mounting trays have had .025 inch <.064 cm) dimples

built in, top and bottom, both sides, so that two new style trays will automatically be spaced
properly.

C. Refer to Figure 2-4 for the KY 196/196E/197/197E mounting dimensions.

D. Secure the mounting rack to the instrument panel per Figure 2-4. The rear mounting bosses

should be attached to the airframe by means of support brackets.

2.3.3

ANTENNA INSTALLATION

A. A conventional 50 ohm vertically polarized

COMM

antenna is requireri with the KY

196/196E/197/197E. Vertical bent whip antennas are not recommenderi. Widehand

COMM

antennas

provide efficient operation over the

COMM

band. Antennas should be installed oer

manufacturer's recommendations. Additional recommendations are as follows.
B. Mount antenna on a flat metal surface or install a qround plane at least 18 inches square.
C. The antenna should be well removed from any projections and the engine(s) anri propeller(s).

Also, for satisfactory operation, the antenna isolation between a communications transmitter

antenna and a NAVreceiver antenna, as well as between dual

COMM

antennas, should be a minimum

of 30dB. VHF antennas mounted on top and bottom have approximately "30dB isolation. A

horizontally polarized NAVantenna and a vertical polarized

COMM

antenna will have practical

values from 10 to 30dB.

D. If both Comm antennas must be top mounted or both bottom mounteri, antenna isolation between

Comm's may not be adequate to prevent reradiation. In single audio panel installations,
reradiation can also be prevented by use of the Xmit-Rec interlock. Refer to Service Bulletin

KY 196/196E-9 or KY 197/197E-10 and Installation Bulletin 194. In dual audio panel

installations where simultaneous operation of both Comm's is desired, the Xmit-Rec interlock
is not recommended. We would recommend adequate antenna isolation, 30dB min.

2.3.4 CABLE HARNESS AND CONNECTOR ASSEMBLY

The KY 196/196E/1971197E uses a speci a l connector that mates di rect ly wi th the printed ci rcui t board
inside the unit. Assembly of the connector is as follows:

A. Contact Terminal Assembly using Molex Crimper (Figure 2-1)

1. Strip each wire 5/32" for contact terminal (KPN 030-1107-XX). (The last two digits of the

contact terminal part number indicates the number of terminals required).

2. Open the Molex hand crimper HT 1921 with the engraved side toward the operator. Place the

conductor tab section of a contact terminal on Anvi l B with the contact oortion facing
away from the operator. Close the crimper slightly untH the contact tabs touch the

female jaw.

3. Insert the stripped conductor until the insulation is even with the side of the crimper

facing the operator. Crimp the conductor tabs by squeezing the handles together until the

jaws are fully closed or a sufficient crimp is obtained.

4. Move the lead to Anvil A. Place the insulating tab section on Anvi-l A. Crimp again until

the jaws are fully closed or a sufficient crimp is obtained.

8. Contact Insertion into Molex Connector Housing

1. After the contact terminals have been installed on the
terminals can be inserted into the proper location in
030-1094-54). The terminal cannot be inserted upside down.

2. The self locking feature can be tested by gently pulling on the wire.

C. Location of Polarizing Key in Housing

1. Prior to insertion of connector into rear of unit, check polarizing key position between

contacts 3 and 4.

2. Refer to Figure 2-5 to check correct position of polarizing key.

D. Extraction of Contact from Molex Connector

1. Slip the flat narrow blade of a Molex contact e;ector tool, HT-1884

(I(PN 047-5099-01),

under the contact on the mating side of the connector. 8y turning the connector upside

down one can see the blade slide into the stoP.

2. When the ejector is sLid into pLace, the retaining tab of the contact is raised, aLLowing

the contact to be removed by puLLing moderateLy on the Lead.

3. Neither the contact or position is damaged by removing a contact; however, the contact

shouLd be checked visuaLLy before reinstaLLing in connector to be certain that retaining

tab "A" extends as shown (see Figure 2-1) for retention in connector.

E. Coax Connector

Refer to Figure 2-3 for the ~etaiLs for mounting the right angLe coaxiaL 9~C connector to the
coax cabLe. InstaLL the connector into the mounting rack.

2.3.5 KY 196/196E/KY 197/197E INSTALLATION

A. Looking at the top of the unit, make sure the front Lobe of the hoLddown device is in a

verticaL position.

B. SLide the unit into the mouting rack untiL the front Lobe touches the mounting rack.

C. Insert a 3/32" ALLen wrench through a hoLd in the front paneL to engage the Locking screw.

Turn clockwise untiL the rear Lobe engages the mounting rack. Continue turning until the unit

is secure in the mounting rack Do not overtighten.

D. For removaL, turn the Locking screw counterclockwise, using a 3/32" ALLen wrench, untiL the

unit disengages from the mounting rack. PulL the unit out of the mounting rack by DulLing on

the metaL tabs Located behind the front paneL on each side of the unit. Radio Extractor KPN

071-6045-00 is designed to aid in the removaL of this and other King products (See Figure

2-2).

POST INST

AllA

TlON CHECK

An operation performance fLight test is recommended after the instalLation is compLeted to insure
satisfactory performance of the equipment in its normaL environment. Check all aircraft control

movements to be sure no electrical cables interfere with their operation. To check the communications
transceiver, maintain an appropriate aLtitude and contact a ground station faci l ity at a range of at

least fifty nautical miles. Contact a ground station close in. PuLL the voLume control knob out to

defeat the automatic squelch feature and listen for any unusual electrical noise which would renuce the

COMI\1

receiver sensitivity by increasing the squeLch threshold. If possible, verify the communications

capability on both the high and low end of the VHF

COMM

band.

NOTE

AS AN ADDED PRECAUTION BEFORE

THE FLIGHT, CHECK THE

ANTENNA.

VSWR SHOULD

BE

CHECKED

WITH

AN

IN-LINE TYPE WATTMETER

INSERTED IN THE

COAXIAL

TRANSMISSION LINE BETWEEN THE

TRANSCEIVER AND THE ANTENNA. ANY PROBLEM WITH THE AItITENItIA
INSTALLATION WILL MOST LIKELY BE SEEN AS A HIGH REFLECTED
?OWER. A VSWR OF 3:1 WILL RESULT IN A 25~ LOSS IN POWER.

NOTE

THE BRIGHTNESS OF THE DISPLAY CAN BE SET FOR THE MOST
PLEASING INTENSITY BY ADJUSTING R130 DURING LOW LIGHT LEVEL

CONDITIONS. R130 IS ACCESSIBLE THROUGH THE BOTTOM OF THE
RADIO WHEN IT IS PARTIALLY PULLED OUT OF THE RACK.
