(1) VFO A
Figure 32: VFOA
VFO A is the main tuning VFO. It consists of a frequency and a band description (related to the selected
frequency). The upper frequency area of the VFO is a Text Box and may be edited as such (click and
drag highlighting, etc).The same holds for the lower area, when it displays a frequency instead of a
band description. The upper area may also be changed by entering a numeric character (without any
mouse interaction). An underline will indicate the digit that will be tuned when hovering over the
frequency display.
See the Tuning Methods on page 133 for more details on how to tune.
Note
that when using the keyboard to enter a frequency, you can return to the previous frequency at any
time by pressing the ‘Escape’ (Esc) key before you press the Enter key.
The red
TX
indicator identifies which VFO is displaying the transmit frequency:
With Split off, the transmit frequency is displayed in VFO A (VFO A
TX
indicator is red)
With Split on, the transmit frequency is displayed in VFO B (VFO B
TX
indicator is red).
The band text information below the frequency gives general information about the FCC Amateur
bands as well as the Short Wave Radio bands and WWV. If not on a recognized frequency, the text will
display “Out Of Band”. If not in an amateur band, the text background will change from black to gray.
Note that this information is only a lookup in a database and has no bearing on the current operating
mode. The band text information can be edited in the BandText table using Microsoft Access.
(2) Tuning Controls
Figure 33: Tuning Controls
VFO Sync
keeps VFO B synchronized to VFO A.
VFO Lock
keeps the frequency from being changed inadvertently. This is a handy feature to use while
in a QSO to keep from accidentally losing the frequency due to clicking in the wrong area or hitting the
wrong key on the keyboard.
The
Tune Step
displays the current tuning rate when using the mouse wheel (or Ctrl + Up/Down
Arrow) to tune the radio. Rotating the mouse wheel away from you will increase the frequency by the
step rate per click while rotating the wheel toward you will decrease the frequency. You can change the
