OPERATION

I.

CW Monitor

Connect the YR-901, the station receiver, and the

TV monitor as shown in Figures 5 and

�6�.tp

When

using  the  video  modulator  to  drive  a  home  televi
sion,  see  page 18  for  details  on  switching  between
channels  3  and  4  for  output  from  the  video

modulator. The  output  impedance  from  the  YR-
901  RF  OUT  jack  is  75  ohms,  so  a  balun  must be
installed  to  provide  a  7 5  ohm  to  300  ohm  un
balanced  to  balanced  feed  for  those  televisions
using  300  ohm  feed  only. The  video  modulator  is
an available option. See your  Yaesu dealer.

We recommend that the television antenna be
disconnected to avoid transmitting the YR-901
output signal from that antenna.

The  preferred  method  of  viewing  the  YR-901
output  is  on  a  video  monitor,  commonly  available
from  computer  hobby  supply  outlets. The  correct

connection method is shown in Figure

�6�.tp

When using headphones to monitor the CW output,

please  do  not  use  the  FT-901 DM  PHONES  jack,
as  this  will  cut  off  the  output  from  the  SP  jack.
Instead,  use  the  PHONES  jack  provided  on  the

YR-901 front panel.

Operation

( 1) Preset the receiver for your favorite beat note

on the FT-901 DM marker signal.

(2) Preset the YR-901 controls and switches as

follows:

MODE .......... CW.B (For Morse Code)
NAR/WIDE ...... WIDE

TTY (45/50) ..... OFF

NEG/POS ....... POS

ACR ............ OFF

POWER ......... ON

(3) Advance the INPUT LEVEL control as neces

sary to obtain a 1 /3 scale indication on the
level indicator LEDs. Now adjust the F. ADJ

control on the rear apron of the YR-90 1 for

maximum deflection of the indicator LEDs.
This will preset the input bandpass filter for
maximu

response on your preferred beat

note. Now turn off the marker.

( 4) Tune in the desired CW signal, and adjust the

INPUT LEVEL control so that the indicator
