FRONT PANEL CONTROLS AND SWITCHES
( 1 )
METER
Depending on the position of the M ETER s witch,
the meter di splays the drive level or the relative
output level of the transmitter,
(2)
POWER
This is the main ON /OFF s witch for the trans
verter .
(3) FUNCTION SWITCHES
SHIFT (UP/SIMP/DOWN)
For 1 44 MHz, this s witch selects ±6 00 kHz repeater
shift, or simplex operation . When the optional
5 0 MHz unit is installed, this s witch selects± 1 MHz
split, or simplex operation .
METER
When set to the input position, the M ETER
selects indic ation of the input level for meter
display . In the PO position, relative po wer output
is displayed .
RCV
In t he N OR position, both transmit and receive
functions are accomplished by the FT- 9 01 DM or
other transceiver . When set to the EXT po sition,
reception is accompli shed on an external receiver .
This is normally used only for satellite operation . .
ALC
This s witch selects the ALC threshold level . For
FM operatio, n , use the S S B/CW position .
( 4 )
RF GAIN
This control sets the receiver RF gain level for 5 0
and 1 44 MHz operation . This control is not used
for 4 3 0 MHz .
(S)
BAND
For 5 0 and 1 44 MHz, t wo bands witch positions are
used . For 4 3 0 M Hz, 5 bandswitch positions are
assigned . Each bands witch position tracks 5 0 0
k Hz, the tuning range of the FT- 9 01 DM .
The SAT . 1 po sition i s for O SCAR Mode A:
1 44 MHz transmit, 2 8 MHz receive. The S AT . 2
position is for O SCAR Mode B: 4 3 0 MHz t r ansmit,
1 44 MHz receive . The SAT . 3 position is for
O SCAR Mode J: 1 44 MHz transmit, 43 0 MHz
receive _ .
(6) TUNE
This control peaks the transmitter section of the
transverter, on the 5 0 and 1 44 MHz band s . This
control is not used for 4 3 0 MHz .
(7) INDICATOR LEDs
These light emitting diode s indicate which band is
being used for transmit and receive, and also
indicate repeater and external receiver operation .
