Asymmetrical Sidebands - live at NAB 2010
If interference issues prevent the use of increased IBOC injection levels on both sidebands, broadcasters will soon have the option to increase only one sideband while leaving the other at levels that do not cause interference with adjacent stations. In this video Research Engineer Philipp Schmid uses a Nautel NV10 to broadcast asymmetrical sidebands at -10dB and -14dB injection levels live from the floor of NAB 2010.
No one else builds single-cabinet, solid-state transmitters with power outputs of 6kW – 30kW in -14dB hybrid mode and 5kW - 21kW for -10dB.
You'll find a number of industry links, white papers and presentations here to help you find out more about the HD Radio™ power increase from both an industry perspective as well as how to upgrade existing Nautel FM products.
This power increase applies to FM stations only. With the exception of a few “Super B or Super C” stations, everyone is eligible to upgrade to -14 dB from -20 dB. The FCC requires notification or in the case of an increase beyond -14 dB, a simple application.
-14/-10dB for Existing Nautel Customers
All NV Series FM transmitters currently shipping contain software to permit operation at elevated sideband power levels (subject to the transmitter’s de-rating chart). For stations which have yet to upgrade, this page may be helpful in planning for the correct size transmitter to meet your goals.
For transmitters shipped before August 1, 2009, contact customer service for instructions on a minor, free hardware modification and make sure software V2.7 is installed. For transmitters shipped after August 1, 2009, verify that software V2.7 is installed and sideband power may be raised (In all cases verify maximum power limits before increasing your transmitter power).
