Which of the following statements is true about PSK31?
Upper case letters are sent with more power
Upper case letters use longer Varicode bit sequences and thus slow down transmission✓Correct answer
Error correction is used to ensure accurate message reception
Higher power is needed as compared to RTTY for similar error rates
Explanation
PSK31 uses Varicode, which assigns the shortest bit patterns to the most frequently used characters; lower case letters are more common than upper case, so upper case codes are longer and typing in capitals lengthens the transmission.
