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.

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).
