As a ham radio operator, maybe some of you will operate or already operated on CW mode. There are many CW QSO guide on the internet and most probably written in English. CW is a great mode, with little power you can work with any heard station on the band just by using a simple antenna such as wire dipole.
There are some countries already abolish the CW test, but here in Malaysia there is still a CW test. United States already abolished CW test to give newer generations a gap to involve in amateur radio.
Here a the sample of CW QSO,
Station A: CQ CQ CQ DE STNA STNA STNA K or CQ DX CQ DX DE STNA STNA STNA PSE K
Station B: DE STNB STNB
Station A: STNB STNB DE STNA TNX FER CALL BT UR RST RST 599 5NN BT HW CPY? KN
Station B: STNA DE STNB GE DR OM BT UR RST RST 599 5NN TOO BT MY NAME IS JOHN JOHN BT HW CPY? BK
Station A: STNB DE STNA RR FB DR OM JOHN BT MY NAME IS SMITH SMITH BT QTH IS IN MOSCOW MOSCOW BT TNX FER QSO HPE CUAGN 73 STNB DE STNA SK EE
Station B: STNA DE STNB QSL DR OM JOHN BT TNX FER NICE QSO CUAGN 73 GL ES GB STNA DE STNB SK EE
As you can see here, there are a few prosigns used. BT, SK, KN and BK.
And also ham radio abbreviation such as GL, ES, GB and DR.
Note for me,
BT also means ( = ) must be send as single sound. dadididida. Sending BT as two sounds is a mistake. dadididit da.
SK means end of contact. Must be send as single sound, didididadida. not dididi dadida. If you use N1MM software as a keyboard keyer software, read the manual. ( [ ) character in N1MM CW macro will send SK properly.
KN when K means "go" or "over", KN is short for "go oNly" and signifies that only the called station should reply. Must be send as dadidadadit, without any spaces between K and N.
BK means break also indicates BacK to you. Used for fast exchange between two stations. Must be send as single character sound, dadidididadida. No spaces between B and K letter.
GL is a ham radio abbreviation that means Good Luck. Send as normal spacing.
ES means And
GB is Good Bye
DR means DeaR
