Note: If in Memory mode and the tuning knob is touched, the radio will go up a level to
Memory Tuning mode. Therefore you may need to press the V/M button to toggle the
display back from MTUNE to M-nnn.)
4. Move to memory location M-003 – Rotate the Select Knob either way until M-003 shows in
the display.– (Lwr L corner of Fnt Panel)
5. Adjust the volume control – Rotate the AF Knob, (but not its SQL/RF outer ring) clockwise
about ¼ turn – adjust as needed. (Upr L Fnt Panel)
6. Adjust the Squelch threshold – Rotate the SQL/RF ring clockwise just to the point the VHF/
UHF background noise suddenly is quiet. (Outer Ring Top L Fnt Panel)
Note: When a signal is received that breaks above the noise threshold it will be heard. This is
much less fatiguing than listening to background noise all the time.
7. Listen first, and if you wish to transmit, press the PTT (Push-To-Talk) button on the side of
the microphone. (Be sure your FCC license permits you to operate at this frequency)
8. Turn the Radio Off – Press and hold the Pwr On/Off button for one second.(Blue button top R
Center of Fnt Panel)
The Select Knob performs many functions on the FT-857D. We just learned in Memory Mode it
selects the memory location to access. In VFO or MTUNE modes, the SelectKnob performs
rapid tuning in two different ways. Simply rotating the Select Knob will increment the frequency
display at a faster rate than the main tuning dial. Alternately, a brief press of the Select Knob
inward will engage the Select Knob to slew the radio in 1-Mhz increments. This is particularly
useful for VHF/UHF when there is a need to move to a frequency at the other end of the band.
Press the Select Knob inward again to return it to the normal rapid tuning rate. Try these now to
get familiar with them.
Task#1 covered basic controls, and Task#2 covered operating from pre-stored memory locations.
Task#3 will intro the Multi Function Key Menu and Task#4 will intro the MENU.
Task #3:
There are two distinct menus: one is called the Multi-Function Key Menu, the other is just called
the MENU. The Multi-Function Key Menu determines what functions the A, B, C keys (found
just below the display.) will perform. It is a list of frequently used functions that is three columns
wide and 17 rows long, labeled MFa through MFq. The current row that is selected is indicated
in the lower portion of the display just above the A, B, C keys. The A, B, C keys are always "hot"
in that they will perform their currently assigned function when one of them is pressed. Changing
the A, B, C keys, i.e.- selecting another row, requires you to briefly press the FUNC key at the
lower left of the display to engage the Select Knob. Once engaged, rotating the Select Knob will
step thru the Multi-Function Key Menu rows. The Select Knob will automatically disengage
within five seconds of non-use and revert to its previous state, (e.g.- rapid tuning).
