3. CORRECT USE OF YOUR CALLSIGN
Use your callsign in a correct way. You have to take a serious exam in order to enjoy this hobby. Be proud of your callsign, it is unique. Only if you use it in a correct way are you making legal transmissions. Ever hear the callsign 4ZZZZ on VHF? As far as I’m aware of, we are dealing with a transmission from a station from Israel and not from Belgium. ON4ZZZZ is the correct callsign. A callsign comprises of a prefix AND a suffix. Even on the HF bands this reprehensible practice can be heard. For analogy, if your car has been stolen, will you report half of the alphanumerics of the number plate to the police, or the complete lot?
AD7MI: always call the DX station with your full call. Always.
