Kenwood USA Corporation
STA Application
IWCE Convention Demonstration
STA File Number 0173-EX-ST-2013

This STA Application proposes the use of Television channel 14 for short-range
demonstration and operation of Kenwood products within the Las Vegas Convention
Center. An engineering study has been conducted, which revealed that no on-air
interference will be caused to any over-the-air television station or low power television
station. All operation will be inside the Las Vegas Convention Center. There will be no
interference to any television viewer from operation in the 470-476 MHz band. The
application also proposes the use of portions of the 900 MHz land mobile band for very
low-power demonstrations of Kenwood radio products at the IWCE land mobile radio
show in March of 2013.

The STA sought is identical to STAs requested and granted in 2005 through 2012 for
operation and demonstration of Equipment Authorized devices at the IWCE trade show,
Las Vegas, Nevada. The Prior STAs were WC9XDC, File Number 0129-EX-ST-2005;
WC9XOF, File Number 0274-EX-ST-2006; WC9XWR, File Numbers 0075-EX-ST-
2007, 0619-EX-ST-2007, 0084-EX-ST-2009; WE9XGZ, File Number 0111-EX-ST-2010
and 0130-EX-ST-2011; and WF9XLC, File Number 0042-EX-ST-2012 in 2012. This
STA request is identical in all respects to that granted by the Commission in 2012.
