Bendix/King KN 64A DME system ver 1.0

Bendix/King description:
Of course, you’ll like as much about the features you can’t see as those you can.
Because behind the redesigned faceplates of the KN 62A and KN 64 is the
Bendix/King quality and reliability you’ve come to know and trust over the years.
These self-contained, 200-channel systems, with their powerful solidstate
transmitters, provide you with search and lock-on in about a second.
What’s more, both the KN 62A and KN 64 can be channeled remotely through almost
any NAV receiver, or tuned directly with their own frequency selection knobs.
They even have duel channeling capability, making two DME frequencies available
to you at all times—one remote, with one stored internally. So what you have,
in effect, is a functional DME HOLD mode.
What you’ll see on the display is the pertinent flight information you need:
Either simultaneous DME distance, groundspeed and timeto-station, or DME
distance and internally selected frequency.
These robust systems operate on any DC voltage from 11 to 33 without adapters or
power converters. But with their modest power requirements, there’s no need for
external cooling.

Easy As 1, 2, 3
You’ll also be glad to know that the KN 62A and KN 64 are as easy on your mind
as they are on your eyes. A three-position function switch makes these systems
extremely simply to use, putting all the information you need and want at your
fingertips.
1. Position one is FRQ, or Frequency, in the center. In this mode, your DME
displays distance and the selected frequency. You can channel the unit
internally using the two concentric frequency knobs.
2. Position two is GS/T, or Groundspeed/Time-to-Station, to the right. In this
position, your DME holds the internally selected frequency while displaying
distance, groundspeed and time-to-station. The "Frequency Hold" feature in this
mode protects you from accidental rechanneling when the frequency isn’t
displayed.
3. Position three is RMT, or Remote , to the left. Here, the DME channels when
you select your NAV frequency on the NAV receiver. When the unit locks on to a
ground station, it displays distance, groundspeed and time-to-station.
While it searches and before it locks, you’ll see only dashes on the display.
That’s it! Full DME functionality made as simple as 1-2-3!

Description:
This gauge is a DME radio which provides the traditional FS DME features along
with a NAV frequency change feature.

The instrument has functional switches and knobs like the real instrument.

The switches and knobs:
See the picture ExplKN64A_SC.bmp which gives an overview of the functions.

The power switch on the lower right side switches the DME on and off.
You can have the power switch always set on and use a central avionic circuit
switch in your main panel to set the power of ALL radios in this package.

The 3-postion function switch on the upper right side determines both the
information displayed and the channeling source.
1. The default position left is the remote (RMT) mode. In this mode the DME
frequency is controlled by the mounted NAV receiver, e.g. KX 155. When in
RMT position, the display shows DME distance, ground speed and the time to
the DME station. If there is no DME signal, dashes are displays instead of
the digits.
2. The frequency (FREQ) position in the middle allows you to change the
frequency directly with the frequency selector knob in the DME radio. In this
mode the display shows the DME distance and the selected frequency.
3. The ground speed and time-to-station postion (GS/T) on the right shows the
same values as the RMT mode.
The frequency is than controlled by a separate NAV radio.

The frequency selector knob on the right side of the radio has two parts: A
large knob and a small knob. The large knob increases/decreases the whole digits
(1 MHz, 10 MHz) and the small knob increases/decreases the fractal digits of the
DME frequency. Clicking in the center of the knob "pulls out" the small knob and
controls changes of 0.50 MHz. When "pushed in" it controls changes of 0.25 MHz.

How to change the DME frequency:
Due to some limitations in FS2002 it is not possible to have the DME frequency
stored as an internally frequency. The result is that any NAV1 radio and the
DME1 radio (or NAV2 and DME2 radios) always use the same NAV frequency. That's
the reason why we use a little trick to get the KN 64A DME radio to work with
the frequency selection.

If the function switch is in RMT (remote) position (this is the default position)
all frequency selections are controlled by the panel mounted NAV radio. If you
have installed the KX 155 NAV/COMM receiver, change the frequency with the
selector knob of the KX 155. If the KN 64A locks in on a ground station that
provides a DME signal, you will see the digits for distance to the station,
ground speed and time-to-station. Otherwise you'll see only dashes on the display.

If you want to change the frequency directly with the KN 64A DME radio, click
the function switch in the middle. It will then be set in FREQ (frequency)
position and the display shows the frequency digits. Clicking twice on the
function switch sets the frequency selection in entry mode and the frequency
digits are blinking. (You can see that your NAV radio has "swapped" the
frequencies for editing. This is one of the limitations we talked about.)
Now you can select a new frequency in the DME radio by using the selector knob.
The changes you are making are directly displayed but the new frequency is not
yet active. To activate the new frequency just click again on the function
switch. Now the DME is ready for navigation if the selected frequency provides a
DME signal.
