the most impotent points to consider when searching for a good digital voice recorder would be the length of recording time, the size of the internal memory, computer interface / connection (USB preferable), format of file saved on your computer, the quality of the recoded message and obviously the price.
When it comes to choosing a digital recorder which does not necessarily records room conversations, but as in our case records a voice signal through audio equipment, or more precisely through a radio scanner output jack - we should consider additional features.
The most impotent list of these additional features would be:

• VOX / VOR - the ability to start and stop recording automatically and only when a sound signal is present (saves recording time, saves battery power)
• External MIC jack - for connecting the digital recorder to the radio scanner
• Time Stamp - digitally register the time the message was recorded (especially useful when you are not present while the recording is taking place)
• Display date & time - this feature is usably available when using a digital voice editor and useful for future reference and documentation
• Digital voice editor - useful when you need to delete part of a message, stitch together two deferent files, clean up background noise, extract important information out of the recorded voice signal etc.

While evaluating a line of popular digital voice recorders we found the Sony ICD-P620 being suitable for most of the features we are looking for in a quality device capable of recording a voice messages received from the radio scanner.
Although this Sony digital recorder is shipped with digital voice editor it is not the recommended one for editing sound messages.
Look for the digital sound editor video tutorials for recommended editor and helpful tips of usage.

The Sony ICDP620 as 512 MB of built-in memory, this Digital Voice Recorder captures up to 260 hours of audio. An ideal device to record class lectures, business meetings, interviews, and even your own memos, the ICDP620 features simple function buttons on the front for easy operation. Features include selectable microphone sensitivity for adjusting the recording levels to your specific needs, three recording modes (LP, SP, and HQ) and four message folders for organizing your messages (up to 396 separate messages).
Also included is a voice activated recording (VOR) mode for added recording convenience, and a large, easy-to-ready LCD screen to keep tabs on the number of messages recorded, recording length, date, time, and battery life. The VOR stops the recording during silent pauses then begins recording again without missing a single syllable thanks to the built-in digital buffer. Other features include a 150mW speaker for clear listening of your recorded files and a date and time stamp that lets you see what day and time you recorded a message.

Powered by two AAA batteries, this voice recorder is USB compatible for downloading recorded audio to PCs running Microsoft Windows 2000 Professional, XP Home, XP Professional, Vista Home Basic, Vista Home Premium, and Vista Business Ultimate operating systems.
