Have you managed to work all call area districts in South Korea using the FT8 digital mode? If so, the FT8 Digital Mode Club (FT8DMC) has an award just for you. It’s called the Worked All Korea Award. To receive it, Amateur Radio operators must demonstrate having made at least one QSO with a South Korean Ham in each of the country’s 6 active call areas (1-5 and 0).
There does not appear to be any separate awards for working all call areas on a single band.
Call areas 1 through 5 are assigned to certain geographical areas of the country. Call area 1 centers around the capital city of Seoul for example. In contrast, “call area” 0 is reserved for science, university and club stations. I managed to work HL0YOTA during a Youth on the Air event. So some special event stations may also be able to use it.
Technically, there are two additional call areas issued by South Korea. But neither count towards the WAKA award. Call area 8 is reserved for South Korean operations on Antarctica and 9 for US military personnel stationed in Korea.
To apply for the Worked All Korea Award, and all other FT8DMC awards, you must install the UltimateAAC application on a Windows machine. That application scans your WSJT-X ADIF log file and will inform you when you’ve qualified for the award at various levels. FT8DMC issues the award in digital form only (JPG or PDF) with no printing or shipping costs. In fact, the award is completely free, like all of their other awards.
