GN Docket No. 12-268

The Office of Engineering and Technology announces the release of updated TVStudy software 
(Version 2.2.4).
1
The TVStudy Version 2.2.4 software installation package, the TVStudy 2.2.4 Installation 
and Upgrade Guide, and the post-auction template XML file are all available on the TVStudy website at 
http://www.fcc.gov/oet/tvstudy.  As with prior updates, a full list of changes from TVStudy Version 2.2.3
is included in the “Differences Between 2.2.4 and 2.2.3” section of the Change Log in the TVStudy 2.2.4
Installation and Upgrade Guide.
TVStudy 2.2.4 contains several new features, including a widely-requested feature allowing users 
to customize records or limit the records to be evaluated in a TV Interference Check study.  It also
corrects a handful of minor issues, including one that occasionally caused larger studies to receive a “leaf 
count too high” error.
For further information regarding the TVStudy software and to submit bug reports, contact Mark 
Colombo at (202) 418-7611 or Mark.Colombo@fcc.gov.
