QRG - Change the frequency to… / What is your frequency?

QRM - Radio Frequency Interference / Do you have interference?

QRT - I stop transmitting / Can you stop transmitting?

QRU - Status / What is your status?

QRZ - Identification / Who is calling me?

QSL - I confirm receipt / Do you acknowledge receipt?

QSP - Forward message

QSY - Frequency change / Can we change the frequency to…?

QTH - Geographic position or location / What is your location?

These Q codes are widely used in contexts where accuracy and speed in transmitting information are essential, such as in amateur radio operations and emergencies. The combination of 10 codes and Q codes offers a complete set of tools for efficient communication in various circumstances.
