Before this feature can be used, it is necessary to set up one or more stepping ranges. To do
this, first select Auto-stepping from the Configure menu. A dialog box will appear,
allowing you to establish the auto-stepping ranges.
To add a range, click on the Add button. Another dialog box will appear, allowing you to
specify the lower and upper frequency limits, the desired step size for that range, the mode,
squelch level, and a text description. The mode, squelch level and description are optional.
You can also edit, delete and move the ranges in the list. If ranges overlap, those at the top of
the list will have higher priority over those lower in the list. You can move ranges higher or
lower in the list by clicking on them and dragging them to the desired location.
If the receiver is not in a specified range, it will default to the fixed step size. If you enter a
different value in the step display, it will change to that step. If the receiver is subsequently
tuned to a defined auto-step range, the step size for that range will be automatically recalled
and will replace the fixed step.
Whenever the receiver is tuned to a defined auto-step range, the display below the main
frequency readout will show the text description for that range regardless of whether auto-
stepping is active or not. If the current frequency coincides with a frequency previously
stored in memory (see below), the memory comment will take precedence over the text
description.
Memory Stepping
Memory stepping allows the user to step directly between frequencies previously stored in a
memory file. In this mode, the callsign of the current memory entry is shown in the step
display.
If the user types in a frequency which does not correspond to a memory frequency, the
receiver will tune to this frequency without problem. If the user then steps the frequency up
or down, the receiver will find the memory frequency closest to the current frequency in the
same direction, and tune to it.
At least one frequency must be stored in memory for memory stepping to work. If the
memory is empty, memory stepping will not function.
Duplex Stepping
Duplex stepping simplifies listening to full duplex
transmissions, which usually have widely different transmit
and receive frequencies. It can also be used to step between
other widely spaced transmissions, which have the same mode.
To set the frequency separation, select Duplex Separation
from the Configure menu. Any separation can be entered, up
to the maximum tuning range of the receiver.
To step up or down by an amount equal to this separation, press the Home or End keys
respectively. If the user attempts to step outside the frequency limits of the receiver, the
command will be ignored.
Memory
WiNRADiO has the ability to store up to 1000 frequencies in a memory file, and the
total number of memory files is limited only by hard disk capacity.
Each entry is assigned the following: a number from 0 to 999, the frequency, mode,
group number(s), callsign and comment.
If the receiver is tuned to a frequency stored in the memory, the associated callsign
and comment is displayed in the area below the main frequency readout.
