3.11 HI/LOW SWITCH
For local FM communication, it is recommended that power
be reduced to eliminate interference to other stations and
to minimize power consumption. By pressing the HI/LOW
switch, transmit power is reduced from 10W to about 1W,
while the RF meter reading is about 2 or 3. Low power
operates in FM and CW modes. In SSB mode, TR-9000
operates on high power, independet of the HI/LOW switch.
3.12 TRANSMITTER PRECAUTIONS
1 . The TR-9000 antenna impedance is 50 ohms. Be sure
to connect an antenna of 50 ohm impedance.
2. Check the transmit frequency before operating to insure
that you do not interfere with other stations.
3. By pressing the microphone PTT switch, The TR-9000
is set in transmit mode; the ON AIR lamp will light and
the meter indicate transmit power. Hold the microphone
about 5cm from your mouth and speak.
4. In SSB mode, microphone gain has been adjusted for op-
timum ALC for normal tone of voice. If you speak too
loud, the signal will distort, reducing intelligibility.
5. In CW mode:
(1) If a key is not connected, CW is transmitted when
the PTT switch is pressed.
(2) With a key connected, operate the dey with the PTT
switch depressed (or the BO-9, optional accessory)
STBY SW to send).
The SIDE TONE circuit will provide a tone about 800 Hz
from the speaker.
• Preparation
1 . Connect the supplied plug to the key.
2. Standby switch:
(1) The microphone PTT switch can be used.
(2) Connect the supplied standby plug to the STBY ter-
minal at the rear. Your standby switch should have a
contact rating of more than 100mA.
(3) By connecting the optional BO-9 system base, the
standby switch on the BO-9 can be used.
Use any of these 3 methods for CW operation.
NOTE:
1. CW receive mode is USB. The AGC time constant is
automatically switched to "fast" in CW mode, and to
"slow" in USB mode.
2. The built-in SIDE TONE circuit allows you to monitor
your station's CW signal.
3. When the key is closed, the SIDE TONE circuit provides
a tone of about 800Hz even in receive mode. Use this
tone as a reference for receiver tuning.
3.14 TONE PAD INPUT
TONE PAD INPUT
The TR-9000 has a 600 ohm TONE PAD input for "auto-
patch" operation in FM mode.
