Which Q signal indicates that you are changing frequency?
The correct answer is B: QSY. QSY is the Q signal that indicates you are changing frequency. Q signals are three-letter codes used in amateur radio for efficient communication.
QSY means 'change frequency' or 'I am changing frequency to...' It's commonly used when operators want to move their conversation to a different frequency, perhaps to avoid interference, to use a more appropriate frequency, or to free up the current frequency for others. When you say 'QSY to 146.55' or send 'QSY 146.55' in CW, you're indicating you're moving to that frequency.
Exam Tip
Change frequency = QSY. Remember: QSY means changing frequency. Think 'QSY = Shift Your frequency'.
Memory Aid
"**Q**SY = **Q**uick **S**hift **Y**our frequency (think 'QSY = Quick Shift Your frequency')"
Real-World Application
You're having a conversation on 146.52 MHz, but the frequency is getting busy. You tell the other operator 'Let's QSY to 146.55' or send 'QSY 146.55' in CW. Both of you then move to 146.55 MHz to continue your conversation on a clearer frequency.

Why Other Options Are Wrong
Option A: Incorrect. QRU means 'nothing for you' or 'I have nothing for you.' It's not about changing frequency.
Option C: Incorrect. QSL means 'I acknowledge receipt' or 'I confirm.' It's used for confirming contacts, not changing frequency.
Option D: Incorrect. QRZ means 'who is calling me?' or 'call again.' It's for calling, not changing frequency.
