A few days ago, I have met a guy in W5 on 15m. He was one of those who finishes his each transmission with BK. I knew there had been such guys anywhere but dared to ask him if it was common to finish transmission with BK. He denied that and explained it had been a kind of habit for him.
I fully understood him. Many people use BK in stead of each other's identification. It must be a kind of habit as he said. Even if the sender is not willing to do so, it hastens me to finish the QSO with him. As a matter of fact, those BK user always finish a QSO without proceeding to "tell me your story" process. I could not help feeling an obvious influence from contesting on this way of operation.
Nowadays, contesting is a dominant style of operation. Plain week day contests are often heard in addition to the contests held at almost every week end. The week end one is often multiple all over the world. Non contesters without WARC band set up like me should keep off the air almost half a week. Some clubs have training programs to educate young beginners to be contesters. No wonder that the contest style QSO has been becoming the standard style of operation.
I still wonder what is the merit of this type of operation. CW is a very slow mode of communication whether they may hasten with use of BK or not. If all of us "contestize" QSO, it may sound like exchange of jargon. Will it attract young people? They will know very soon that such jargon or symbol exchange is totally meaningless. I have already mentioned of this contest style QSOs as loss of the form in QSO. I don't think it will bring anything good to the future of ham radio. It deprives rich possibilities of ham radio communication on this mode.
Ending with BK, where do you go in a hurry?
