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 .
