* Notes:
Additional Information: FCC Rules Part 97 (Amateur Radio Service)
Transmitter power must be maintained at the minimum necessary to carry out the desired communications. Unless otherwise noted, the maximum power output allowed is 1500 watts PEP.
All classes are limited to 200 watts PEP in the 80, 40, and 15 meter Novice/Technician Plus subbands.
30 Meters: Limited to 200 watts PEP output. Avoid interference to the fixed services outside the US
10 Meters: Novice and Technician Plus are limited to 200 watts PEP output
Technician Class has no privileges below 30 MHz
Modes of Operation (Emission Types; § 2.201 of the FCC Rules):
CW - International Morse code telegraphy emissions having designators with A, C, H, J or R as the first symbol; 1 as the second symbol; A or B as the third symbol; and emissions J2A and J2B.
Phone (Voice) - Speech and other sound emissions having designators with A, C, D, F, G, H, J or R as the first symbol; 1, 2 or 3 as the second symbol; E as the third symbol. Also speech emissions having B as the first symbol; 7, 8 or 9 as the second symbol; E as the third symbol.
MCW for the purpose of performing the station identification procedure, or for providing telegraphy practice interspersed with speech. Incidental tones for the purpose of selective calling or alerting or to control the level of a demodulated signal may also be considered phone.
Image - Facsimile and television emissions having designators with A, C, D, F, G, H, J or R as the first symbol; 1, 2 or 3 as the second symbol; C or F as the third symbol; and emissions having B as the first symbol; 7, 8 or 9 as the second symbol; W as the third symbol.
MCW - Tone-modulated international Morse code telegraphy emissions having designators with A, C, D, F, G, H or R as the first symbol; 2 as the second symbol; A or B as the third symbol.
RTTY - Narrow-band direct-printing telegraphy emissions having designators with A, C, D, F, G, H, J or R as the first symbol; X as the second symbol; X as the third symbol.
Data - Telemetry, telecommand and computer communications emissions having designators with A, C, D, F, G, H, J or R as the first symbol; 1 as the second symbol; D as the third symbol; and emission J2D. Only a digital code of a type specifically authorized in this Part may be transmitted.
