(2) Class of Emission
Under the Radio Regulations published by the International Telecommunication Union (ITU) classification of emissions are designated by groups of three characters.
The types of emissions defined here are grouped according to the third character.
(a) Continuous Wave (CW) : Amplitude-modulated transmission by on/off keying the main carrier intended for aural reception.
Morse : Morse telegraphy intended for aural reception using any classes of emission ending in A.
Telephony : Telephony using any classes of emission ending in E.
Television : Television using any classes of emission ending in F. This may only be used in frequency bands above 1 GHz.
Radio Teleprinter (RTTY) : Automatic telegraphy using any classes of emission ending in B. This includes teleprinters using any CCITT recognized codes, and
morse telegraphy intended for automatic reception.
Data : Data using any classes of emission ending in D. The Radio Regulations require that transmissions between amateur stations in different countries shall be
in plain language. All transmissions shall therefore be restricted to using CCITT recognized codes (in plain language).
Facsimile : Facsimile using any classes of emission ending in C.
Slow Scan Television (SSTV) : Television operating in a narrow bandwidth using any classes of emission ending in F.
(b) Simultaneous use of combinations of any of the preceding types of transmission, e.g. Telephony and Data, are described as classes of emission ending in W.
(c) Pulse : Pulse using any classes of emission ending in P. This may only be used in frequency bands above 1 GHz.
(3) 􀗤率
(甲) 最大􀗤率是指供應給天線的無線電射頻􀗤率􀎖最大􀗤率會以載波􀗤率規定􀎖對具有抑制􀎕可變或減幅載波的發射Ε有關􀗤率會在線性的情況下由峰功􀗤率(p.e.p.)決定􀎖至

(丙) 5.725 – 5.850 GHz 頻帶的操作Ε最大等量全向輻射􀗤率限制為6dBW􀎖
(乙) 發射帶寬必須可確保能最有效率地使用有關頻譜︰一般例說﹐帶寬必須保持在科技及有關業務許可可容許的最低值􀎖若使用帶寬擴展技術Ε則必須採用符合有效率地使用
頻譜的最低頻譜􀗤率密度􀎖不過Ε無論使用何種發射類別Ε所擬發射佔用的帶寬Ε須符合在認可頻帶以外不可超過其平均發射􀗤率1%的規定􀎖這1%不功括諧波和寄生
發射所功含的􀗤率􀎖
(3) Power
(a) Maximum power levels refer to the radio-frequency power supplied to the antenna. These levels will be specified by carrier power. For emissions having a
suppressed, variable or reduced carrier the power shall be determined by the peak envelope power (p.e.p.) under linear conditions. For pulse emissions the mean
power shall not exceed the carrier power and the peak power shall not exceed the p.e.p. stipulated for that frequency band.
(b) For mobile operation in the frequency band of 144 - 146 MHz and allocated bands in the 430 - 440 MHz a maximum of 14 dBW erp is permitted. For portable
operation the corresponding limit is 7 dBW erp.
(c) For operation in the frequency band 5.725 - 5.850 GHz, a maximum of 6 dBW equivalent isotropically radiated power (e.i.r.p.) is permitted.
(d) The bandwidths of emissions shall be such as to ensure the most efficient utilisation of the spectrum : in general this requires that bandwidths be kept at the
lowest values which technology and the nature of the service permit. Where bandwidth-expansion techniques are used the minimum spectral power density
consistent with efficient spectrum utilisation shall be employed. However whatever class of emission is in use the bandwidth occupied by the intended emission
shall be such that not more than 1% of the mean power of the transmission shall fall outside of the authorized bands. This 1% does not include the power
contained in harmonic and spurious emissions.
(4) 無線電引致的意外
(甲) 由於強烈的射頻幅射可能會有害﹐所以三􀙨安􀙤限制適用於人們暴露於該種幅射中的地點︰-
