When someone calls me, he/she often gives me only his/her call. DE , K or even my call is omitted. It makes me puzzled from time to time. With a filter of 400Hz on as always, their frequency could be a bit off from mine. There could be a delay in timing they start calling me. In both situation, I am not sure if I am called by him/her. When they are not loud enough, it is even more perplexing to me.
Omitting such as DE, K or my call in calling me could spare time for him/her. I could hardly believe so. If I could not be sure I was called, we should spend some long time to confirm that. Or do they believe that omitting that way is a kind of smart and modern operation? They should be disciplined to send message in most understandable way in communication of this mode.
Sometimes, I am inclined not to respond to them at all. Could I cope with such callers in that way?
Giving my call and DE, K etc when calling me is an orthodoxical method. There are reasons for that. It enables me to recognize you calling me easily. Your signal might not be so loud as you hear me. Or your rig is offsetting the grequency from me a bit.
In addition, I hope them not to end their message in transmission with BK without any identification. They do that all of sudden. I am sometimes frightened listening them in relaxation with my feet on the operaating table. In such a case, I should rush sitting back on my chair with back straight again. Apart from that my move in the shack, I should get ready for next transmission abruptly. This kind of operator always starts with the above mentioned style. To those BK senders, I would finish the QSO as soon as possible.
Sending identifications in the beginning and ending of transmission is necessary for the audience to recognize you and me and for me to get ready for my turn.
There is time enough.
