The WPX SSB that year was further reduced to only one team BT4AG participating. From the OP list, this is a special channel of BY4SZ. They narrowly beat last year's BY1PK with a score of 2875QSO/295 million points and wrote a new WPX SSB record.
Recalling that the competitions in those years were still a very big thing. After all, competitions were not the mainstream of amateur radio activities in our country at that time. As an introductory HAM of that era, he didn't even know the things written above, not only was unable to participate in it personally, Even ordinary daily QSO is very strange.
