ASCII (also known as ITA5 or IRA) is an amateur radio telegraphy signal using the ITA-5 alphabet. Can come in either 7-bit or 8-bit format. The 7-Bit ASCII mode has 170 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). FSKFrequency-Shift Keying shift, and about 300 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). of bandwidth, where the 8-Bit ASCII mode uses a 492 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). shift and about 600 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). of bandwidth. The ASCII mode typically runs at 110 or 300 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second., but can be seen with 50, 75, 100, 150, 180, 200, and 600 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second., or any non-standard baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. rate between 50 and 1200.
