Explanation

1

A1A

Telegraphy without the use of a modulating audio frequency (by on/off keying) for aural reception.

2

A3C

Facsimile (with modulation) of the main carrier either directly or by frequency - modulated sub-carrier.

3

A3E

Double sided telephony.

4

C3F

Television by analogue modulation and vestigial-sideband operation.

5

F1A

Telegraphy for aural reception is including DATA by means of frequency shift-keying without the use of a modulating audio frequency whereby one or two frequencies are being emitted at any instant.

6

F1B

Telegraphy is including DATA by means of frequency shift-keying without the use of a modulating audio frequency whereby one or two frequencies are being emitted at any instant.

7

F1D

Data transmissions by means of frequency shift-keying without the use of a modulating audio frequency, with one frequency been emitted at any instant.

8

F2A

Telegraphy for aural reception including RTTY and DATA by the on/off keying of a frequency or by means of the on/off keying of a frequency modulated emission

9

F2B

Telegraphy including RTTY and DATA by the on/off keying of frequency modulating audio frequency or by means of the on/off keying of a frequency modulated emission.

10

F3C

Facsimile by direct frequency modulation of the carrier.

11

F3E

Frequency-modulated telephony.

12

G3E

Phase-modulated telephony.

13

J3E

Single, sideband-suppressed carrier telephony.

14

J3F

Single, sideband-suppressed carrier, modulated by slow scan television audio frequencies.

15

Non

Emission of an unmodulated carrier.

16

R3E

Single, sideband, reduced or variable level carrier telephony.

17

W9E

Digital speech multiplexed up to twelve channels.

18

J2D

Data transmission with the use of a modulating auto frequency.

19

J2E

Digital telephony with the use of a modulating audio frequency.
