The Yaesu FT-891 is a fantastic little power house of an HF transceiver! Packing 100 watts in a radio the size of an old car stereo, do NOT let its size fool you. Although it may not have the fancy colorful animated waterfalls like some of the HF radio, it packs a punch when it comes to reaching out and touching someone. With a good antenna you will log thousands of contacts with the Yaesu FT-891!!!
At the time of this writing the FT-891 is $639.95
INNER KNOB - AF Knob -
The inner AF knob adjusts the receiver
audio volume levels of the internal or
external speaker. Clockwise rotation
increases volume level.
Outer Ring Knob -
Rotate this knob counter-clockwise to reduce the
background noise and the system gain. Rotate this
knob fully clockwise to set the gain to the highest
level for normal operations. Counter-
clockwise rotation will raise the start position of
the S-Meter indication. When receiving a strong
signal, the noise is reduced and the signal is emphasized.
indication is set just about the same as the
receiver noise level.
This control may be changed to function
as the squelch control by selecting “SQL” on
Menu Mode “05-05 [RF/SQL VR]”.
MULTI function knob -
This knob incorporates multiple tasks and makes
it very convenient to operate the various
functions of the FT-891.
1 Adjusts the operating
frequency of VFO-A in 500 kHz Steps (except the for
AM and FM modes)
2 Adjusts the operating frequency of VFO-B
3 Operates the [A]/[B]/[C]/ [CLAR] key function
4 Selects the Desired memory channel
5 Switches the Setting Modes ON/OFF
6 Changes the Menu Mode setting values
➠ FUNCTION-1 ➠FUNCTION-2 ➠ CW SETTING ➠
Select the desired function from the Setting
Modes, and then press the MULTI
function knob to switch the selected function ON or OFF.
Press and hold this key to activate the Menu mode.
In the SSB mode, IF SHIFT permits moving the DSP filter
passband higher or lower, without changing the pitch of the
incoming signal, and thus reduces or eliminates interference.
Press this key to display the IF SHIFT
● [B] (SCP): The SCOPE function
The SCOPE function provides a spectrum display of the band
conditions. Press this key to display the band condition
When the SCOPE function is active, the [A]/[B]/[C] keys are
automatically changed to the below operations.
[A](SPN) key: This key changes the displayed bandwidth.
Available selections are 750 kHz, 375 kHz, 150 kHz, 75 kHz, or
37.5 kHz ranges.
[B](SWP) key: Each time the [B](SWP) key is pressed, a new
scan of the spectrum scope is shown on the LCD display.
The SWP icon blinking on the LCD is confirmation that the
“Continuous Sweeping mode” is running.
[C] (NB): Noise Blanker function
The IF Noise Blanker can significantly reduce the noise that is
caused by automotive ignition systems.
During reception, press this key, and then rotate the MULTI
function knob to adjust the VFO-A RX clarifier offset value up
to ±9.998 kHz.
The clarifier offset value (frequency) can be restored to “0
(zero)” by pressing the MULTI function knob for more than one
This is the main tuning dial for the transceiver. Rotate this knob
clockwise to increase the operating frequency and rotate it
counterclockwise to decrease the operating frequency.
Pressing the [PWR/LOCK] key briefly will engage or release
the DIAL knob lock.
Press and hold this key for more than one second to write
the frequency and the data presently displayed on VFO-A
to the quick memory bank (QMB).
This key will copy the saved data from a written memory
channel to VFO-A. Press this key to display the “MEMORY
CHANNEL” list screen.
Rotate the MULTI function knob to select the desired
previously written memory channel.
Press this key again to copy the currently selected memory
channel data to VFO-A.
This key is used to save the data from VFO-A to a memory
channel. Press this key to display the “MEMORY CHANNEL” list
Rotate the MULTI function knob to select the desired memory
Press this key again to copy the VFO-A operating data to the
selected memory channel.
This key toggles frequency control between the VFO and the
number is displayed like “M01”.
Pressing this key momentarily, exchanges the frequency and
memory channel data of VFO-A and VFO-B.
Press and hold this key for one second to set VFO-A and VFO-B to
the same frequency and data values.
[BAND (MODE)] key
Press this key to change the tuning of the MAIN DIAL to a
higher step rate. The “FST ” will be displayed at the bottom right
corner of the screen.
The tuning steps for the MAIN DIAL knob are set at the factory
to 10 Hz -100 Hz for one step and 20 kHz for each dial rotation, in
the SSB/AM/CW/RTTY/DATA Mode (One kHz for each step and
200 kHz for each dial rotation in the FM Mode).
The Indicator glows green while the squelch opens on receiving
signals. The Indicator glows blue: While Zeroing during CW mode.
On receiving a signal with a CTCSS/DCS tone matching the
squelch tone code setting of the transceiver.
The Indicator glows red when transmit is engaged.
Press and hold this key to turn the transceiver ON or OFF.
Briefly press the key while the transceiver is ON to engage the
MAIN DIAL knob lock. This key toggles the MAIN DIAL knob lock

Similar to the 991A Diagram on this site, the FT-891 has multiple menus that you are not seeing displayed in teh graphic above. If I remember corerctly there were about 60 menu items on the 891 that most of whihc you will set it and forget it.
