Vertex Standard FT-1000MP SUB VFO-B RX & TX Switch-LED, Lock Button, SUB SQL Knob, Pitch Knob

If the [ENT] key is pressed first, the yellow labels on the keys become effective, for manually entering any frequency one digit at a time; press [SUB(CE)] then [ENT] to enter Sub-VFO frequencies directly.

35. SUB VFO-B [RX & TX Switch-LED]

These lamps select and indicate the current status of Sub VFO-B. When the green “RX” lamp is lit, the receiving frequency is under control of SUB VFO-B. When the red “TX” lamp is lit, the transmitting frequency is under control of SUB VFO-B. During dual receive operation, the green “RX” lamps above both tuning knobs Main and Sub) will be illuminated.

36.SUB VFO-BTuning Knob

This knob adjusts the Sub VFO-B operating fre- quency. The available tuning increments are the same as described for the main tuning knob, although each tuning knob’s increments may be set independently (see page 38).

37. [LOCK] Button

This button toggles locking of SUB VFO-B tuning to prevent accidental frequency changes. The red in- dicator in the display glows when this command is ac- tive (the tuning knob can still be turned, but it does nothing). Press the [LOCK] button again to re-enable the tuning knob.

38. SUB SQL Knob

This separate control sets the signal level thresh- old at which SUB VFO-B receiver audio is muted (and the green “SUB BUSY” display indicator turns off), in all modes. This control is normally kept fully CCW, except when scanning and during FM operation.

39. CW and Electronic Keyer Controls

[SPOT] button turns the CW receiver spotting het- erodyne oscillator on and off.

[BK-IN] button turns full break-in (QSK) CW opera- tion on and off.

[KEYER] button toggles the internal CW keyer on/ off, as indicated by the LED above this button.

[SPEED] knob adjusts the keying speed of the keyer.

40. PITCH Knob

Rotate this control to select your desired CW tone pitch (from 300~1050 Hz, in 50 Hz increments), as shown in the display. The Tx sidetone, receiver IF pass- band, and display offset from the BFO (carrier) fre- quency are all affected simultaneously.

FRONT PANEL CONTROLS

41.[CLAR] Buttons

Pressing the [RX] button activates the CLAR knob, to allow offsetting the receiving frequency temporarily (see item 42 below). The [TX] button provides the same function for the transmit frequency. If both buttons are pressed, the receiver and transmitter are both offset from the original frequency. Pressing the [CLEAR] but- ton zeroes any offset tuned by the CLAR knob. Each memory and VFO retains all Clarifier settings indepen- dently.

42. CLAR Knob

This knob tunes the Clarifier offset frequency up to

9.99kHz when activated by the CLAR [RX] [TX] but- tons just below it (a 3-digit display appears in the cen- ter of the display (if enabled) when the Clarifier is ac- tive).

43. NOTCH Knob

This knob adjusts the IF notch frequency when this feature is activated by the [NOTCH] button located above this knob. When activated, the LED inside the [NOTCH] button glows red.

44.IDBT Indicator

This red indicator lights up when the IDBT System is activated by pressing the [IDBT] button on the Shuttle Jog. When this indicator is illuminated, the EDSP (Con- tour) filter’s bandwidth and center frequency changes according to the SHIFT and WIDTH knob settings.

45. SHIFT Knob

This knob offsets the center frequency of the IF passband when rotated from its “normal” (center) po- sition. This control functions in all modes except FM.

When the IDBT System is activated by pressing the [IDBT] button on the Shuttle Jog, the EDSP (Con- tour) filter’s passband offset changes according to this knob’s setting.

46. WIDTH Knob

This knob, when turned from center, reduces the overall IF bandwidth from either the lower or upper side, from the maximum selected by the [BANDWIDTH] but- tons.

When the IDBT feature is activated by pressing the [IDBT] button on the Shuttle Jog, the EDSP (Con- tour) filter’s passband width is reduced according to this knob’s setting.
