.
.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
.

.
.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
