Amateur Radio Stack Exchange is a question and answer site for amateur radio enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. In either case, other stations then reply with their callsigns. What's the difference, and when should I attempt contact?
This became clear to me after a bit of time to think, but it wasn't at all clear on initially jumping in. It helps to know the formal definitions of the codes used:.
The station is asking for new contacts from anyone. The station is asking for a calling station to repeat their callsign. Only a station which has already attempted to contact them should speak at this time. During contests, a popular station say DX has a pileup with lots of stations trying to make contact. A station will often merely say QRZ for picking up someone from the pileup. Thus, in this I am agreeing with the previous answer but with the following comment. I believe that this method of saying QRZ is now so popular in this pileup situation that is, commonly done by many that it has actually changed the use of QRZ over the years from its original intent of not fully copying a call sign or questioning the caller to repeat his call sign.
Whether it is correct to use QRZ in this way -- makes no difference -- this is what people are doing. As said by other answerers, it's typically the station announcing 'I'm ready for more contacts at this time.
It is kind of informal usage, as Kevid Reid mentioned, the official QRZ definition is 'who is calling me? The contest station will usually only use CQ if they're not getting responses. Typically, when a contest station says QRZ, you should reply by saying your callsign once , and quickly, especially if there is a pile-up. It is considered very rude to repeat your callsign many times. One of the worst examples I've heard was after a DX station said QRZ, a station responded with their callsign and 'I know you're hearing me, just answer and I'll stop calling!
This just causes more irritation to those trying to communicate, especially when the operator is talking over those who are in communication. These are specially designed transceivers that instantly retransmit signals heard in their receivers. They are typically located on tops of buildings or at the summits of hills or mountains, and use tower-mounted antennas to provide over wide areas. Most repeaters operate on the 2 meter and 70 cm bands. There are various ways to find a repeater. Modern transceivers often include a scan mode that searches for activity.
Some transceivers will even place active frequencies in their memories automatically. Once you find a repeater to use, take some time to listen and familiarize yourself with its operating procedures.
If the repeater is quiet, pick up your microphone, press the switch, and transmit your call sign. This advises others on frequency that you have joined the system and are available to talk. After you stop transmitting, the repeater sends an unmodulated carrier for a couple of seconds to let you know it is working.
If you want to join a conversation already in progress, transmit your call sign during a break between transmissions. The station that transmits next should acknowledge you. BREAK generally suggests an emergency and indicates that all stations should stand by for the station with emergency traffic.
After one of the other hams acknowledges you, politely ask to make a quick call on the repeater. Usually, the other stations will allow you this brief interruption. Make your call short. If your friend responds to your call, ask him to move to a simplex frequency or another repeater, or to stand by until the present conversation is over.
Thank the other users for letting you interrupt them to place your call. Find A Class Use our class locator to find a class offered in your local area. Learn More. Secure Site Login Forgot Password? Making Your First Contact Operating Tips Watch other hams make contacts to familiarize yourself with the process, but don't be afraid to make your first contact. Some general rules apply: Position the microphone about one inch from your lips. Speak in a normal tone of voice.
A high ALC reading indicates that you are overdriving your radio and possibly distorting your signal. Hams usually switch their radios from transmit to receive and back by pressing the Push to Talk PTT button on the microphone or by using a foot switch.
For hand or desk microphones, avoid stabbing or punching the switch. Not only does this shorten the life of the switch, it can send a loud click at the beginning of your transmission. When the VOX is on, the sound of your voice will automatically switch the transceiver into the transmit mode. If you must use VOX, speak into the microphone at a normal voice level.
When you start speaking, the transmitter should activate automatically. When you finish speaking, the transceiver should return to the receive mode after a short delay. Sometimes the VOX may trigger in response to background sounds. If so, look for the VOX Gain control. You can adjust this control to eliminate the problem. A speech processor takes a normal voice signal, which varies constantly as you speak, and processes the signal to minimize fluctuating power levels.
The result is an SSB signal that has consistent power at the highest level possible. Speech processing is good when you are operating at low power or with a poor antenna. After that, you can either chat or part ways and find someone else to call.

This applies to meters, with an international DX window. On most other bands of 20 meters and up, there is no set calling frequency.
On 20 meters, there is a maritime frequency of Helpful 9 Not Helpful 4. Many repeaters 2m, 70cm you do not have to call CQ. Helpful 2 Not Helpful 0.
