TUNING THE MARK-V FT-1000MP

Tuning is accomplished in several ways, with each method having its own advantages; they are:

¦Main & Sub VFO Knob Tuning

¦Shuttle Jog Tuning

¦Panel & Microphone Down/Up keys

¦VFO Channel Stepping

VFO Knob

Rotating the Main VFO-A knob tunes the transceiver ac- cording to the se- lected tuning step size and encoder tuning rate. Both of these settings are configured via menu selections 1-3& 1-4(see page 99). The table below shows

the available tuning step sizes and their default set- tings.

Control	Tuning Steps	Default Step
MAIN VFO-A knob	0.625/1.25/2.5/	10 Hz
SUB VFO-B knob	5/10/20 Hz
Shuttle Jog	13 preset	–
DOWN(q)/UP(p)	Normal	100 kHz
Pushbuttons	w/[FAST] knob	1 MHz
VRF/MEM CH	Normal	10 kHz
CH. Stepping
CLAR	0.625/1.25/2.5/	10 Hz
(Clarifier)	5/10/20 Hz

Shuttle Jog

The Shuttle Jog ring is more efficient for large fre- quency excursions, or whenever QSY requires spin- ning the VFO knob a lot, while still providing positive control with a comfortable feel.

R o t a t i n g t h e Shuttle Jog away from the center de- tent in either direction starts constant tun- ing. The farther the S h u t t l e J o g i s moved from center, the larger the pro- gressive frequency steps (and QSY). There are 13 preset frequency steps incrementing through the arc of the Shuttle Jog (from 10 Hz ~ 100 kHz). The Shuttle Jog speed (encoder rate) is also configurable from 1 ~ 100 msec. via menu selection 1-1on page 99.

Recall that the step size varies as the Shuttle Jog is turned, while the encoder rate is fixed. The effect of tuning faster as the Shuttle Jog is rotated actually comes from jumping to progressively larger tuning in- crements, as encoder rate remains constant.

For faster dial tuning rates with either the VFO knob or mic UP/DOWN buttons, press the [FAST] button below and to the left of the Main VFO knob (“FAST” appears). This selects the VFO speed, which can be switched between 4x (default) and 2x in menu selection 1-0(see page 99). This affects the ΔF per VFO knob rotation without changing the default tuning step size.

Default		ΔF for 1 revolution of VFO knob
Tuning		(X2) Encoder Rate			(X4) Encoder Rate
Step		Normal		FAST	Normal	FAST
0.625 Hz		312	Hz	3.12 kHz	625 Hz	6.25 kHz
1.25	Hz	625	Hz	6.25 kHz	1.25 kHz	12.5 kHz
2.5	Hz	1.25	Hz	12.5 kHz	2.5 kHz	25 kHz
5 Hz		2.5 Hz		25 kHz	5 kHz	50 kHz
10	Hz	5	Hz	50 kHz	10 kHz	100 kHz
20	Hz	10	Hz	100 kHz	20 kHz	200 kHz

FAST Button Operation

By default, the front panel [FAST] button is a press- on, press-off type. However, you can change it to a momentary type by recalling menu selection 8-0(see page 104) and changing the default setting.
