Following is a full list of ScanNow features:
for Windows NT/95 (registered)
ScanNow 1.0 for Windows NT/95 (unregistered)
AR8000 Serial Interface
AR8000 Serial Interface from CAT Technologies
Homebrewn AR8000 Serial Interface
ScanNow is now available for general audience! You can download a
shareware version of ScanNow from this
page. It is fully functional but will not save frequency database into
a file or upload anything to the scanner.
The complete version of ScanNow is available for only $35US. While this fee is low enough to make it affordable to anyone, it will allow me to continue development of this software. You can obtain registered copy in one of following ways:

ScanNow is based on a C++ library designed to control scanners in general and AR8000 in particular. It will be freely available from this site for anybody who wants to write scanner control applications.
To run ScanNow, you will need the following:
Following tutorial will show you how to use ScanNow and demonstrate some of the features available in the program. Click on the tabs to see different panels.
This is the Manual Tuning Panel which appears when you start ScanNow. From this panel, you can tune scanner to any frequency as if you were using its built-in keyboard. There is also simplified access to the modulation type, step size, and other parameters. Accessing them via AR8000's keyboard is somewhat difficult as it requires pressing the FUNC button.
The Frequency Panel provides you with access to the frequency database. All frequencies are organized in a tree structure. There are two kinds of entries in this structure, marked with different icons:
To enter a frequency entry (as opposed to a range entry), simply set its From and To fields to the same frequency, or uncheck the Range box.
When you press the right mouse button on the frequency tree, a pop-up menu appears with the following options:
The Scan Panel shows the status of frequencies being monitored for activity. For every entry, its name in the database, actual frequency, and modulation type are shown. When scanning is on, ScanNow will continuously go through the list and check signal levels plotting them on the graphs, from left to right.
If scanning was switched off for some reason (for example, ScanNow was temporarily switched into manual tuning), the corresponding parts of graphs are left gray.
Double-click on a scan list entry will automatically tune the scanner to selected frequency and switch you to the Manual Tuning Panel.
When you press the right mouse button on the scan list, a pop-up menu appears with the following options:
The Search Panel is used to display results of the range search and modify its parameters. The range search is performed in the background, i.e. while you are using other features of the program. A graph shown on the screenshot is used to display signal strength distribution in the searched frequency range. Following controls are available:
When Hunting is on, the search creates a
timestamped entry in the frequency database.
All searched frequencies for which signal strength exceeds the Hunt
Threshold will then be stored under that entry and labeled in a
WFM 98.7MHz (60%)
| | |
| | +---- Relative signal strength
| +----------- Frequency
+----------------- Modulation type
The "active" entry under which search stores
its results is labeled with a special icon (see above). Frequencies can be
cut from it and pasted somewhere else. Entire entry can also be cut. In
this case, search will create a new entry as
soon as the first new frequency is found.
The Direct Console Panel allows to communicate with the scanner directly, using its built-in commands. The direct communication should be used with extreme care though, as many commands may disturb ScanNow operations. Commands are typed in the box at the bottom of this panel. The upper half shows responses coming from the scanner.
The About Panel gathers all controls which didn't find their place in other panels. Those include Communications and General settings.
You will be automatically switched to this panel if ScanNow hasn't been able to establish communications with the scanner. In this case, you need to change communication settings and restart ScanNow.
The Scanner Panel gives user access to specific features of AR8000 scanner, such as internal search ranges and scan banks. The functions of buttons at this panel are pretty self-explanatory. All information downloaded from the scanner will appear as timestamped entries in the frequency database.
