Dan,
This is copied from the ARC250 Manual:
ARC250basic:
- Enhanced editor for memory channels, trunk id’s and search range data
- Virtual Control screen, control your scanner from a PC. The PC displays a near 100% copy of the scanner display.
ARC250pro:
ARC250PRO includes all options of ARC250basic plus:
- Search range extender: add 200 custom programmable search ranges
- History log: software shows all the latest activity, the last 100 hits (frequencies/trunk id’s/detected subtones) are stored
- Logging to disk: log all data to disk using the CSV file format
- Audio recording: automatically record WAV files. The filename of each wav file contains: frequency / trunk id / start / end time and date
- The color and fonts are user programmable
Of the 5 additional features in Pro, I use all but Audio Recording and will likely use it at some time in the future.
