Regulations Concerning the Amateur Service- Published by the Bundesministerium für das Post - und Fernmeldewesen - Prepared by the Fernmeldetechnisches Zentralamt                   The following classes of emission may be used by amateur stations subject to the provisions of 2.4:  2.4 Restrictive Provisions                                                                                                       2.4.1 Television and facsimile transmissions; telex traffic.      2.4.1.1 According to Article 7, the content of television and facsimile transmissions shall be confined to subjects which amateur stations are allowed to transmit. These transmissions shall not be of a broadcasting nature, shall not contain any advertising and shall not be made public.   2.4.1.2 For telex traffic below 146 MHz frequency deviation shall be limited to ±500 Hz when F1B is used and to ±3000 Hz when F2B is used. DESCRIPTION TYPE OF EMISSION DESIGN. Amplitude modulation = emission in which the main carrier is amplitude-modulated (including cases where sub-carriers are angle-modulated) Double-sideband, a single channel containing quantized or digital information, without the use of a modulating sub-carrier.                 MORSE TELEGRAPHY DIRECT-PRINTING TELEGRAPHY FACSIMILE    TELECONTROL                 A1A A1B A1C A1D Double-sideband, a single channel containing quantized or digital information, with the use of a modulating sub-carrier.                 MORSE TELEGRAPHY DIRECT-PRINTING TELEGRAPHY FACSIMILE    TELECONTROL                 A2A A2B A2C A2D Double-sideband, a single channel containing analogue information.                 FACSIMILE  TELEPHONY TELEVISION (VIDEO)               A3C A3E A3F Vestigial sideband, a single channel containing analogue information.                 TELEVISION (VIDEO)               C3F Single-sideband, suppressed carrier, a single channel  containing quantized or digital information, with the use of a modulating sub-carrier.                 MORSE TELEGRAPHY DIRECT-PRINTING TELEGRAPHY FACSIMILE TELECONTROL          J2A J2B J2C J2D Single-sideband, suppressed carrier, a single channel  containing  analogue information.                 FACSIMILE TELEPHONY TELEVISION (VIDEO)          J3C J3E J3F Single-sideband, reduced or variable level carrier, a single channel containing   analogue information.                 TELEPHONY UNMODULATED CARRIER (for test purposes) R3E N0N Frequency modulation (F), phase modulation (G) = emission in which the main carrier is angle - modulated Frequency modulation, a single channel containing quantized or digital information, without the use of a modulating sub-carrier.                 MORSE TELEGRAPHY DIRECT-PRINTING TELEGRAPHY FACSIMILE TELECONTROL F1A F1B F1C F1D Frequency modulation, a single channel containing quantized or digital information, with the use of a modulating sub-carrier.                 MORSE TELEGRAPHY DIRECT-PRINTING TELEGRAPHY FACSIMILE TELECONTROL F2A F2B F2C F2D Frequency modulation, a single channel containing analogue information.  In the amateur service phase modulation may also be used.          In individual cases the phase - modulated emission whose class of emission corresponds to the frequency - modulated emission indicated in the table may be used. The first basic characteristic "F" shall be replaced in that case by"G"(e.g.F1A=G1A).               FACSIMILE TELEPHONY TELEVISION (VIDEO) F3C F3E F3F
