Ssb Transmission - Yaesu FT-1000MP Operating Manual

Operation
has 39 of its own) during reception, whenever you
tune to the same part of the band again.
When you use the tuner the first time on an
antenna, set the RF PWR control to around the 9
o'clock position, to minimize interference you
might cause others, and also to minimize stress
on the tuner, feedline, and antenna (in case there
is a high SWR). Ensure beforehand that the fre-
quency you will transmit on is clear of other sig-
nals. Also, if you want to monitor the tuner's action
visually, set the meter Ic/SWR selector to display
SWR.
When the channel is clear, press the TUNER
button. The indicator comes on, indicating
the ATU is activated, and the indicator next
to it appears while the tuner seeks the proper
matching settings (and, if monitoring SWR on the
meter, you should see the tuner select the lowest
possible reading). When the indicator turns
off, you are ready to transmit (assuming the
indicator didn't light).
After using the antenna tuner, the indica-
tor will remain on (unless you press the TUNER
button to turn it off), and the indicator will
appear occasionally when you change frequency,
indicating that the main microprocessor is report-
ing the frequency change to the tuner coproces-
sor (reception is unaffected). If you have tuned
far enough to possibly require rematching, it will
reset itself to the new range (if it has any pre-
viously stored settings for the new range). How-
ever, when you first connect a new antenna, the
tuner will not have the correct settings stored in
these memories, so you will need to "train" the
tuner, by pressing the TUNE button whenever you
change to a new band or frequency range (for this
antenna).
If you want to use an external ATU or manual-
type tuner, the internal ATU can be disabled via
menu selection 8-8.

SSB Transmission
To transmit in LSB or USB mode:
OC Make sure the appropriate mode indicator is lit,
and set the meter ALC/COMP selector to view
ALC.
Of this is the first time you are transmitting SSB
with the FT-1000MP, preset the MIC and RF
PWR controls to about the 12 o'clock position,
and make sure the VOX is off (button out).
(Check the RX and TX LEDs above the tuning
knobs to determine which frequency you're go-
ing to transmit on, and make sure is not
showing to the left of the main frequency dis-
play.
To transmit, just press the PTT (push-to-talk)
switch on your microphone, and talk.
To determine the optimum setting of the MIC
control for your microphone, adjust it while speak-
ing into the microphone (at a normal level) so that
the meter deflects to about midrange on voice
peaks (the upper end of the red ALC range). Once
found, this setting can be left as it is unless you
change microphones.
You can adjust the RF PWR control for more or
less output, from about 5 to 100 watts (on the
upper PO meter scale), as desired. However, you
should always use the lowest possible power out-
put to maintain reliable communications — not
only as a courtesy to other stations, but to mini-
mize the possibility of causing RFI and TVI, and
to reduce heat generation and maximize the life of
the equipment.
Transmitter Monitor
The transmitter monitor is ac-
tually a separate receiver circuit joy MONI
which picks up a sample of your
transmitted RF signal, allowing
you to hear accurately how the . .
signal sounds. This feature is
very helpful for setting up the speech processor
controls, among other things.
