Release

Chanalyzer 3.0 Beta 5 has been released! If you are still using Chanalyzer 2.1 we strongly encourage you to give this beta try. You can keep Chanalyzer 2.1 installed in case you want to continue to use it as well. Chanalyzer 3.0 adds a sidebar with lots of useful features like device signatures, recording notes, recording cropping, and a data inspector.

This is a 2.1.x maintenance release. It fixes bugs with the preferences file, and re-enables support for WiFi channel 14.
Fixes and Updates:

• Fix a bug with the preferences file
• Re-enable support for WiFi channel 14

We've added channel reports to provide more information about Wi-Fi and Zigbee channels. A channel "grade" is also given, which is an indicator of how quiet the channel is. The channel with the highest grade should be the best channel to install a new network on (given a long enough data sample).

Fixes and Updates:

• Scroll spectral view with the mouse wheel
• Relative fast forward and rewind (speed based on timeframe)
• Added Channel Reports (Wi-Fi and Zigbee)
• Fixed startup race condition that occasionally caused crash

Grab it from our downloads page.

This is the final planned 2.1.x maintenance release. This version makes better use of screen real estate by clipping the views at -30dBm unless stronger signals are present. It also adds an error reporting mechanism and fixes some minor spectral view issues.

Fixes and Updates:

• Clip Planar and Topo views at -30 dBm unless stronger signals are present
• Automatically notify of new releases and provide details on new features/fixes
• Catch unhandled exceptions (program crashes) and provide option to report them via email
• Improve performance when changing timeframe in a long recording
• Fix partial spectral data line when moving back in time via the playback bar
• Fix playback position string getting clipped for large values

This Chanalyzer release coincides with the release of Wi-Spy 2.4x (FINALLY!!!). I hope that this is the final 2.1.x maintenance release. We've fixed all the issues we're aware of, and we are hard at work on some cool new features for Chanalyzer 2.2.

Fixes and Updates:

• Add support for Wi-Fi channel 14 (2473-2495 GHz)
• Use calculated noise floor for spectral color mapping
• Update noise floor after every minute of data
• Improved "Save Recording as..." bounds checking
• Don't allow opening USB tab after device is disconnected
• Improved Playback bar usability
• Use Time Frame from preferences in new tab when USB device is plugged in
• Fix issues when rapidly switching playback position
• Fix issues when reaching beginning or end of a recording
• Fix amplitude labels at initialization
• Fix behavior when Preferences dialog is closed
