1)Display - The backlit, liquid crystal display provides
the current status of the SW8 such as frequency,
mode, bandwidth, etc. Refer to the 'FRONT PANEL
DISPLAY' section of this manual for a full description.
2)TUNING (VFO) - The dial and the
and
buttons are the primary tuning controls of the SW8.
Clockwise rotation of the dial increases frequency and
counterclockwise rotation decreases frequency. The
dial also incorporates variable speed tuning. The faster
the dial is rotated, the faster the tuning speed.
The
button increases and the
button decreases
the frequency by fixed steps (10 kHz or
9 kHz, selectable on the AM broadcast band, 5 kHz on
the Shortwave band, 100 kHz on the FM broadcast
band and 25 kHz on the Aircraft band) with each
depression. Pressing and holding either button will
allow continuous stepping up or down as long as the
button is depressed.
3)Program Buttons -
