C. Frequency Selection
Note the primary frequency display in Figure 2. The frequency is displayed down to a
resolution of 1 Hz. (There is a menu option to hide the least significant digit and only
display frequency to the nearest 10 Hz.)
If the frequency can't be changed. Look for the SPEECH/LOCK button, located under
the tuning dial. Press and hold for 1 second to unlock the front panel. When in the middle
of an operation, if may be helpful to lock the front panel (same way as you unlock it) so
that you don't inadvertently tune off frequency.
Tuning using the tuning dial. The MHz digits, kHz digits, and Hz digits are three
different touch zones. Here is how to use them.
• Touch the MHz digits to select the band of operation. A popup screen lets you
make a choice. Touch and hold the MHz digits for 1 second to set the tuning rate
to 1 MHz/step if you need to quickly tune across the band.
• Touch the kHz digits to enable coarse tuning mode. Touch and hold the kHz
digits to select the coarse tuning step size. The choices are 1 kHz to 100 kHz per
step. 5 kHz is customary on 2m, and 25 kHz is customary on 70 cm. On HF,
pick a tuning step that is convenient.
• When operating on HF, touch the Hz digits to access fine tuning. Touch and hold
the Hz digits to select the fine tuning step size. The choices are 1 Hz per step or
10 Hz per step.
Direct frequency entry. The radio has provision for direct frequency entry, but it's very
well hidden!
• Touch the MHz digits to select the band of operation. While the popup screen is
active, one of the buttons is labeled F-INP. Press that button to obtain the direct
entry screen.
• On the virtual keypad, enter the desired frequency in Mhz. In other words, use a
decimal point between the MHz and kHz digits. Or skip the decimal point and
enter sufficient trailing zeroes to put the significant digits where you want them.
• The direct entry screen has a few other tricks that we won't go into here. See the
manual for details.
