How are the audio input and output of a transceiver connected in a station configured to operate using FT8?
- A.To a computer running a terminal program and connected to a terminal node controller unit
- B.To the audio output and input of a computer running FT8 software (correct answer)
- C.To an FT8 conversion unit, a keyboard, and a computer monitor
- D.To a computer connected to the FT8converter.com website
WhyIn an FT8 station, a transceiver's audio input and output connect to the audio output and input of a computer running FT8 software. FT8 is decoded and encoded entirely in software, so the transceiver's audio input and output connect directly to a computer's sound card, running the FT8 program, answer B. A describes the older packet-radio setup with a terminal node controller, which FT8 doesn't use, C invents nonexistent hardware, and D references a made-up website rather than software running on the operator's own computer.
