ET Docket No. 13-26

GN Docket No. 12-268

On July 22, 2013, the FCC's Incentive Auction Task Force released Version 1.2.6 of the
TVStudy software for performing interference analyses using the methodology described in
Bulletin No. 69 (OET-69). As a result of user feedback and FCC staff testing, OET is today
releasing an updated Version 1.2.7 of the TVStudy software. Among other things, this update
adds the capability to do pair-wise studies in countries other than the U.S., including cross-
border studies of interference between U.S. and Canadian or Mexican stations on proxy
channels; provides improved sorting of stations' records in the user interface; and corrects a
potential issue that could cause spurious out-of-memory and SQL key errors. A complete
change list is included on the web page listed below. The update includes new source code and
executable files for both the Mac and Linux platforms, an updated instruction manual, change
log, and upgrade guide. None of the underlying data files are being changed and need not be
replaced. It is recommended that all TVStudy users apply this update so that results will match
those obtained by the FCC.
All of these files are available on the FCC website at:
OET invites interested parties to provide feedback, and to meet with OET staff regarding
the installation and operation of the TVStudy software to help ensure consistent results.
Additionally, a non-FCC e-mail user group (list-serve) is open to interested parties at
