Radio Calls (QSO) – General Rules of Conduct

A QSO is radio contact between two or more hams – a two-way radio connection.


  • to make a general call (CQ),
  • to answer someone’s CQ or
  • to call someone who has just ended their connection with another station.
  • there are other options, but we will focus on them according to the topic of the publications.

Which initial should come first in your conversation? First pass the initial of the person you are talking to, followed by your initial.

The correct one: “LZ1ZZZ here (or from, or dis is, or nothing) LZ2ZZZ” (you are LZ2ZZZ, and LZ1ZZZ is the radio amateur you are calling).

How often should you identify yourself? In most countries, the rule is: at the beginning and end of each broadcast, but not less often than once every 5 minutes. A series of short cues is usually considered one general transmission. In a contest, it is not strictly necessary from a legislator’s point of view to identify yourself in every QSO. The five minute rule has become a requirement for monitoring services to be able to easily identify each station. From the point of view of operator practice, however, the only good procedure is to identify yourself in each QSO (details will be read in other posts on this site).

Pause or Wait: When your correspondent transfers the transmission to you, it is a good habit to wait a second before starting your transmission to check if anyone else wants to join you or use the frequency.

Short or long broadcasts? Preferably do short rather than long broadcasts, this makes it easier for your correspondent if he wants to comment on something you said.
