The SWL QSL Museum Korea Asia KBS Daegu (Taegu) - HLKG (2.510 Mhz) - 1977 - "AI" Station Overview QSL Contributed by Bill Harms (USA) "AI" Station Overview The Famous 1977 Reception A DXer managed to pick up a weak, unexpected  signal from the regional South Korean station on 2510 kHz. The transmission was explicitly identified on-air in Korean as "KBS Daegu, HLKG". Instead of receiving a standard printed card from a central office, the listener was sent a warm, custom handwritten verification letter directly from the local station.  It was personally signed by Mr. Oh Kap-hwan, who was working as a TV transmitting engineer at the Daegu branch at the time. The 1977 QSL verification from KBS Daegu (HLKG) is widely considered a legendary and highly prized rarity among long-distance radio listeners (DXers)
