A fixed channel is available for common use on all bands by

installing a crystal in the socket on the AF-GAN unit (X49-

1110-01). The crystal frequency can be computed by the

following formula;

Crystal Frequency (MFIz) = 5.5 MFIz — X

Frequency (MFIz).

X = Band Switch frequency (1.5, 3.5, etc.)

Crystal specifications; See Fig. 4-7

NOTE:--------------------------------------------------------

Operating

TRIO-KENWOOD does not supply crystals.

The shift stet circuit CW frequency between transmit and

receive, and the RIT circuit are not effective in FIXED
CHANNEL OPERATION.

To use the fixed frequency oscillator, depress the FIX push

switch.

4.7 CW OPERATION (Fig. 4-8)

For CW operation, your transmit frequency should be

"zeroed" to the transmit frequency of your contact station.

Receive frequency is 800 Hz lower than the transmit fre

quency of your contact station, so that his signal is received

as an 800-Hz beat note. This also allows your contact to

receive your signal without having to retune his receiver.

Tuning methods are detailed in the following paragraphs.

4.7.1. OPERATION WITHOUT AN OPTIONAL

CW FILTER

Set the IF SHIFT control to its center position and the RIT

switch OFF Adjust the main tuning control for an 800-Hz

beat note and your transmit frequency will then coincide

with that of your contact station ("zeroed"). During recep

tion, the side-tone monitor is activated by pressing down the

key (VOX OFF). In this case, listen to the side-tone superim

posed on the receive signal and adjust the main tuning for

similar side-tone and incoming CW audio tone. By so doing,

transmit frequencies will be zeroed.

You may now adjust the RIT for a pitch which suits your

preference. If intereference is encountered, adjust the IF

SHIFT. For more convenient and effective CW operation,

use of the optional YK-88C or YK-88CN CW crystal filter is

recommended.

4.7.2. OPERATION WITH A CW FILTER

Set the IF SHIFT to its center position and the RIT to OFF.
Adjust the main tuning control for maximum deflection of

the S-meter. Receive signal pitch will be about 800 Hz, in
dicating correct tuning.
