ARLA/CLUSTER: Dados do Novo Repetidor DIGITAL

[Salomao Fresco]

Olá a todos!

Impõe-se aqui uma rectificação à minha mensagem de ontem que referia o modo
D-Star como G9W, quando afinal deverá ser — G7W
Só deverá ser considerado F1E, quando o equipamento utilizado funcionar
apenas como um transceptor de FM não transmitindo qualquer outro tipo de
informação.
A informação que segue abaixo foi retirada do site da FCC.

Aguardo os vossos comentários!

*Emission Designator List*
*Emission Designators:** The following system of designating emission,
modulation and transmission characteristics shall be employed.
*a) Emissions are designated according to their classification and their
necessary bandwidth.  b) A minimum of three symbols are used to describe the
basic characteristics of radio waves. Emissions are classified and
symbolized according to the following characteristics.   1. First Symbol -
type of modulation of the main carrier.
2. Second Symbol - nature of signal(s) modulating the main carrier
3. Third Symbol - type of information to be transmitted.  c) First Symbol -
types of modulation of the main carrier.   1.Emission of an unmodulated
carrier*N*  2.Emission in which the main carrier is amplitude-modulated
(including cases where sub-carriers are angle-modulated):
Doubled-sideband*A*   Single-sideband, full carrier
*H*   Single-sideband, reduced or variable level carrier*R*   Single-sideband,
suppressed carrier*J*   Independent sidebands*B*   Vestigial sideband*C*  3.
Emission in which the main carrier is angle-modulated:    Frequency
modulation*F*   Phase Modulation*G*  Note: Whenever frequency modulation "F"
is indicated, Phase modulation "G" is also acceptable.   4. Emission in
which the main carrier is amplitude and angle- modulated either
simultaneously or in a pre-established sequence*D*  5. Emission of pulses:
  Sequence of unmodulated pulses*P*      . A sequence of pulses:

   . Modulated in amplitude
*K*      . Modulated in width/duration*L*      . Modulated in Position/Phase
*M*      . In which the carrier is angle-modulated during the period of
pulse*Q*      . Which is a combination of the foregoing or is produced by
other means*V*  6. Cases not covered above, in which an emission consists of
the main carrier modulated, either simultaneously or in a pre-established
sequence, in a combination of two or more of the following modes amplitude,
angle, pulse*W*  7. Cases not otherwise covered*X* d) Second Symbol - nature
of signal(s) modulating the main carrier:   1. No modulating signal*0*  2. A
single channel containing quantized or digital information without the use
of a modulating sub-carrier, excluding time-division multiplex*1*  3. A
single channel containing quantized or digital information with the use of a
modulating sub-carrier, excluding time-division multiplex*2*  4. A single
channel containing analogue information*3*  5. Two or more channels
containing quantized or digital information*7*  6. Two or more channels
containing analogue information*8*  7. Composite system with one or more
channels containing quantized or digital information, together with one or
more channels containing analogue information*9*  8. Cases otherwise not
covered*X* e) Third symbol - type of information to be transmitted:   1. No
information transmitted*N*  2. Telegraphy - for aural reception*A*  3.
Telegraphy - for automatic reception*B*  4. Facsimile*C*  5. Data
transmission, telemetry, telecommand*D*  6. Telephony (including sound
broadcasting)*E*  7. Television (video)*F*  8. Combination of the above*W*  9.
Cases not otherwise covered*X*
