ABOUT - Single Side Band
http://en.wikipedia.org/wiki/Single_Side_Band
-Claims- In Amateur Radio, LSB is traditionally used
below 10 MHz and USB is used above 10 MHz.
However Read - LSB/USB Chaos on the Bands...

FWIW - It has alway been my understanding :
* Generally "LSB" {Lower-Side-Band} is used by Amateur {Ham}
Radio Operators BELOW 7 MHz. {7,000 kHz}
* Generally "USB" {Upper-Side-Band} is used by Amateur {Ham}
Radio Operators ABOVE 7 MHz. {7,000 kHz}
US Navy AFN Shortwave Radio uses "USB" {Upper-Side-Band}
* Current AFN / AFRTS Shortwave Radio High Frequencies
AFN-SW - http://myafn.dodmedia.osd.mil/ShortWave.aspx
WWV and WWVH use a 'modified' Double Side-Band {DSB}
http://en.wikipedia.org/wiki/WWV_%28radio_station%29
with Suppressed Carrier (DSB-SC) for their Time Signal
Transmissions on 2.5 MHz, 5 MHz, 10 MHz, 15 MHz
and 20 MHz. WWV => http://tf.nist.gov/stations/wwv.html
Many/Most Commercial High Frequency (HF) Broadcasts
use "USB" {Upper-Side-Band}

CB {Citizens Band} Radio uses both LSB and USB.
