I said the ITU recommends that Amateurs have technical knowledge of "radiotelegraphy". Telegraphy, over radio or wire, does not always mean Morse code. Amateurs should be aware of the many means available to them to transmit text, an on/off carrier is one, so is frequency shift keying. Isn't that what I said? If I'm calling anyone "stupid" it's not the ITU. Automated Morse code, I would guess. Radiotelegraphy/radioteletype. Frequency shift keyed digital data. Radiotelegraphy/radioteletype. No, those with a designator of A or B are radiotelegraphy. Although in common nomenclature radiotelegraphy tends to refer to text that is intended to be received by ear and radioteletype tends to refer to text that is intended to be received automatically. The words can be used interchangeably. You seem to want to split hairs where there are no hairs to be split. If your sending text it's radiotelegraphy or radioteletype, therefore an A or B designation. If your sending data then its telemetry, telecommand, or some non-text, non-image, arbitrary binary data such as a computer program, therefore a D designation. If your sending an image digitally then it is considered an image transmission, therefore a C designation. All the above can be sent with an FSK system. F1A - manual telegraphy, likely Morse code F1B - automated telegraphy, such as acsii F1C - image, such as JPEG F1D - data, such as telemetry F1E - digitized voice But I'm getting off track. Radiotelegraphy means more than just Morse code.
