Split Frequency Operation - Yaesu FT-1000MP Operating Manual

Split Frequency Operation
Typical split operation involves receiving on the
Main VFO (A) or a memory channel, and transmit-
ting on the Sub VFO (B). The special case of FM
repeater operation uses some features of its own,
and is described in the box on page 41.
Rare DX stations often announce that they will
"listen up" or "listen down" a few kHz (from their
Tx frequency) when calling CQ or during contests
to avoid being covered by the DX pileup from
responding stations that often occurs.
To activate Split operation, you can either
press
F l
or the
TX
button/LED above the Sub
VFO-B tuning knob. In either case appears
at the left of the display, and the red
TX
LED above
the Sub VFO tuning knob lights. Split operation
can be activated with or without dual reception,
however, we recommend that you have dual re-
ceive on, to allow you to monitor your transmit
frequency on the Sub VFO (while receiving), as
well as the Main VFO receiving frequency, so you
don't accidentally "step on" somebody.

Split Operation Modes
The FT-1000MP offers three modes of Split
operation (chosen by menu selection 8-2):
Normal
-
in this default configuration, pressing
1 - 1
activates Sub VFO-B for transmission. Other
settings (such as mode and frequency) must be
manually set for the Sub VFO.
Auto
-
when is pressed, Sub VFO-B is
enabled for transmit, and the selected operating
mode from Main VFO A is automatically copied
into Sub VFO-B. The transmission frequency
must still be manually set for the Sub VFO.
A- B
-
same as Auto mode above, however, a
preset frequency off set (known as a "Quick Split')
is also applied to Sub VFO B for transmission.
The "Quick Splif' is handy when you know the
offset a DX station will be listening on beforehand.
The offset is applied instantly, saving time and

pressing this activates the Sub VFO for
transmission.

VFO B for each Split operating mode. Also recall

previous contents. the current offset between the two VFOs).
