4. Operation - Transmitting
You can use the VOX circuit for yr switching, if
desired, and the transmit monitor to listen to your
signal. See also the box below for FM Repeater opera-
tion.
The FT-1000 includes seein Sepre specifi-
cally intended for operation on FM repeaters
above 29 MHz which use 100-kHz splits.
To locate these repeaters, you can ask around the
calling channel (29.6 MHz), or you may want to
load a block of memory channels (page 32) with
50-kHz frequency multiples from 29.61 to 29.7
MHz (and FM mode, of course), Then set the
squelch so that the receiver is silent on a clear
channel, and press M SCAN to scan the memories.
When you find a repeater, press the RPT bution,
once for "~" shift (to transmit 100 kHz below
your receiving frequency), Pressing it again will
select "+" shift, but this is not used above 29.6
MHz. Press it once more to return to simplex.
Try a quick identification transmission to make
sure you have the shift right (the FT-1000 also
automatically transmits a low-level 88.5-Hz sub-
audible tone during FM Repeater transmissions,
to access those repeater that require it).
Once you have made contact through the repea-
ter, you can store the frequency, mode and
repeater shift settings in memory (page 32) for
later recall.
Clarifier (Rx/Tx Offset Tuning)
The three CLAR buttons near the upper right corner
of the front panel and the contro! just below them are
used to offset either the receive, transmit or both fre-
quencies from their settings on the main display. The
three small numbers in the center of the display (just to
the right of the main frequency display) show the cur-
rent clarifier offset. The clarifier controls on the FT-
1000 are designed to allow you to preset an offset (up
to £9.99 kHz) without actually retuning, and then to
activate it with the clarifier's RX and TX buttons.
Perform the following steps, if you like, to familiarize
yourself with the clarifier controls:
* Turn the CLAR knob back and forth while watching
the center of the display. Notice that a minus sign
appears when the offset is negative.
page 28
* Now, with a non-zero offset displayed, press the RX
button several times while watching the display.
When the clarifier is activated, RX CLAR appears at the
top center of the display, and the main frequency
display shifts by the amount displayed for the clari-
fier offset.
¢ Press the PTT switch and notice that the transmit
frequency remains the same as the original frequen-
cy display when the receive clarifier is on.
¢ With the receive clarifier active, turn the CLAR knob
again, and notice that both the main frequency and
the clarifier offset displays change together.
* Now press the clarifier CLEAR key and observe that
the offset is cleared to zero, and the main vfo fre-
quency returns to what it was originally.
The transmit clarifier works almost the same way as
the receive clarifier, by pressing the clarifier TX button.
TX CLAR appears at the top center of the display when the
transmit clarifier is active. The offset is only added to
the displayed operating frequency, however, when you
transmit.
A typical application for the clarifier is when you
are in contact with a station whose transmitter drifts (or
perhaps you didn't have him quite tuned in when you
called him). You don't want to change your transmit-
ting frequency, as that would force him to retune — you
just want to adjust your receiver, You could proceed as
follows while listening to his signal:
* Press the clarifier CLEAR button if the displayed clari-
fier offset is not zero.
¢ Then press the clarifier RX button to activate the
receiver clarifier, and carefully retune his signal with
the CLAR knob,
After you finish your conversation with him, you
must remember to press the clarifier RX button again to
turn off the clarifier. However, if you hear another
station you want to call right on the frequency he was
on, instead of turning off the clarifier, you can just press
the TX clarifier button to bring your transmitter onto the
same frequency, and make your call (now both the
receive and transmit frequencies are offset by the dis-
played amount). Keep in mind, however, that you will
need to press both the RX and TX clarifier buttons again
to turn off the clarifier when you finish. You might also
want to Clear the offset when done.
The FT-1000 actually has an independent clarifier
for each vfo, on every band and alternate subband, plus
one on each of the 99 memories. This means that
clarifier TX/RX and offset settings are not carried over
when you change bands or memory channels, but
rather are stored until you return to that vfo, band,
subband or memory again.
