Three 144 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. FSKFrequency-Shift Keying signals in a 3100 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). VFTVoice Frequency Telegraphy (Voice-Frequency Telegraphy) bandwidth. Reportedly phased out.
VFTVoice Frequency Telegraphy (Voice-Frequency Telegraphy), i.e. a technique that uses the entire voice-frequency range 300-3400 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). for sending multiple transmissions simultaneously over one voice-bandwidth radio channel so that the entire frequency bandwidth of the channel is used.
