What are Q Codes?
Q Codes are a globally understood form of communication between amateur radio operators. Each code is made up of three letters always starting with the letter ‘Q’ (Example: QRL, QSO, QTA.) Using different combinations of letters, Q Codes allow radio operators to transmit commonly used phrases quickly and without language barriers. Knowing them all is a valuable asset to anyone interested in ham radio or emergency preparedness.

Q code review

Sorry, but this app didn’t do anything at all for what I expected. It seems to be a clumsy program for Q codes.
