Note: 20 Meter phone expansion.....Effective: May 22, 1983 . AMTOR..............................Effective: Jan. 22, 1983 . .DIGITAL COMMUNICATIONS: (F1, 3.5-28 MHz)(A2, F1, F2 above 28 .MHz) . . BAUDOT: (International Alphabet #2) . A2, F1, F2: Maximum frequency shift = 900 Hz . A2, F2: Highest modulating frequency = 3000 Hz. . Maximum speed = 100 wpm (75 baud). . . ASCII: Maximum baud rates: . 3.5 - 28 MHz = 300 baud . 28 - 50 MHz = 1200 baud . 50 - 220 MHz = 19600 baud . 220 - up = 56000 baud . . AMTOR: TOR specifications are found in CCIR Rec. 476-2. . (100 baud, Block rep rate 2.222/sec.) . . OTHER DIGITAL CODES: (ABOVE 50 MHZ ONLY): . Any other digital code may be used above 50 MHz . in the domestic U.S. (Except where A1 only is . permitted). A description of the code and modu- . lation technique must be kept in the log. . . Bandwidth limitations: . 50 - 220 MHz = 20 kHz max. . 220 - 1215 MHz = 100 kHz max. . 1215 and up = any Bw if in accordance with . 97.63(b) and 97.73(c). . . NOTE: When any digital communications are used, ID must . be given by voice or CW, whichever is . appropriate. . .FACSIMILIE and TELEVISION: . . Below 50 MHz the bandwidth of A4, A5, F4, F5 must not . exceed that of an A3 SSB signal. . . 50 to 225 MHz: . The bandwidth of A4 and A5 SSB emissions must not . exceed . that of A3 SSB emissions. . . The bandwidth of A4 and A5 DSB emissions must not . exceed . that of A3 DSB emissions. . . Type F4 and F5 emissions shall be limited to a peak . deviation of 5 KHz with a maximum modulating frequency . of 3 KHz. Alternatively, the bandwidth shall be no . greater than 20 KHz. . . Below 225 MHz, type A4 and A3 or type A5 and A3 . emissions are allowed simultaneously on the same . frequency if the bandwidth is no greater than type . A3 DSB. . .-------------------------------------------------------------- . The present complete emission types are given in the . format: . "Numeral, Letter, Numeral, Letter". The first numeral . indicates the bandwidth of the signal. This is often not . shown (and really should be for an accurate . description). . The first letter shows the type of main carrier modulation. . The second numeral indicates the type of modulating . signal . (voice, TV, CW, etc). The suffix letter, also not always . shown, basically indicates carrier and sideband type . information (full carrier or supressed, SSB or DSB etc). . The following list is not complete, does not show . pulse modes, and does not mean that all these can be used . by the amateur. . . TYPE DESCRIPTION NOTE . . (Amplitude Modulation) . . A0 carrier - no modulation . A1 on-off telegraphy #1 . A2 amplitude modulated telegraphy #1,2 . A3 DSB (full carrier telephony) . A3A SSB (reduced carrier telephony) . A3B (2 independent sidebands - . reduced carrier) #3 . A3J SSB (supressed carrier telephony) . A4 DSB facsimile . A4A SSB facsimile, reduced carrier . A4J SSB facsimile, supressed carrier . A5 DSB television . A5C VSB television #4 . . (Frequency Modulation) . . F0 carrier - no modulation . F1 frequency shift telegraphy #1 . F2 frequency modulated telegraphy #1,2 . F3 telephony . F4 facsimile . F5 television . . --------------------------Notes-------------------------- . .1. This is not restricted to Morse - may be RTTY, for example. . (RTTY could be run on 160 meters if on-off keying of . the carrier is used). . .2. Examples of this mode are: 1) Carrier keyed on/off 2) . carrier on with the modulation keyed on/off 3) carrier . on with the modulation frequency shift keyed. . .3. This is used by short wave broadcast station studio to . transmitter links with separate programs on each set . of sidebands. . .4. VSB = Vestigial sideband where all of one set of sidebands . is transmitted but only about 20 percent of the other set . of sidebands is transmitted (the lowest frequencies). .______________________________________________________________ . Common Amateur emissions: . . Double sideband voice = 6A3 . Single sideband voice = 3A3J . VHF FM voice = 16F3 . 25 wpm Morse cw = .1A1 .
