[K3] Date mode question

[David F. Reed-2]

When I am using MT63 in MARS service (1 KHz wide), we use a center
frequency of 1KHz, so a pass band from 500 Hz to 1500 Hz; when I set
date mode, and pick either the 2.7 KHz or 2.1 KHz filter, the data mode
seems to cut off at a lower frequency of 1 KHz or so; is there an easy
way to shift the pass band down where I want it?

Thanks and 73 de Dave, W5SV / NNN0SLA

  Dave,

Yes there is an easy way, just turn the SHIFT knob to set the center
frequency (while adjusting, it is displayed in the VFO B area) - the
default is 1500 Hz.  The since you want to use a 1 kHz width, adjust the
WIDTH knob until you see 1.00 in the VFO B display area.  If the SHIFT
and WIDTH LEDs are not illuminated, tap one of the knobs to switch from
the LO - CUT - HI selection.

If you use these adjustments frequently, they can be saved in one of the
presets.

73,
