G8A06
Which of the following is characteristic of QPSK31?
Pick an answer to check it.
Answer: D. All these choices are correct
QPSK31 is sideband sensitive (you must use the right sideband), adds error correction to its encoding, and takes about the same bandwidth as BPSK31. So all the statements are true.
Tip: QPSK31: same width as BPSK31, plus FEC.
