Rev 2.02 ELEMENT 4 - EXTRA CLASS QUESTION POOL Valid July 1, 2008 through June 30, 2012 741 questions total SUBELEMENT E1 -– COMMISSION’S RULES [6 Exam Questions - 6 Groups] E1A Operating standards: frequency privileges for Extra Class amateurs; emission standards; automatic message forwarding; frequency sharing; FCC license actions; stations aboard ships or aircraft Carrier Frequency -2.8 KHz Lower Side band Carrier Frequency Upper Side band Carrier Carrier - 300 Hz +300 Hz Carrier Frequency +2.8 KHz E1A01 When using a transceiver that displays the carrier frequency of phone signals, a displayed frequency of 3 kHz below the upper band edge will result in a normal USB emission being within the band. E1A02 When using a transceiver that displays the carrier frequency of phone signals, a displayed frequency 3 kHz above the lower band edge carrier frequency display will result in a normal LSB emission being within the band. E1A03 With your transceiver displaying the carrier frequency of phone signals, you hear a DX station's CQ on 14.349 MHz USB. It is not legal to return the call using upper sideband on the same frequency because your sidebands will extend beyond the band edge. 14.349 MHz + 3 KHz = 14.352 MHz. The band edge for 20 meters is 14.350 MHz therefore your signal would be out of band by 2 KHz. Band Plan (larger copy in appendix) Jack Tiley <strong>AD7FO</strong> Page 7 3/15/2009
