In Australia, Roland Lang, VK4FB, and Stefan Durtschi, VK4CSD, completed what is being claimed as the world’s first FT8 contact on 122 GHz. The distance spanned during the August 11 contact was 92.08 kilometers (approximately 57.1 miles). Signals were –17 dB on one end, and –20 dB on the other. Earlier this summer, VK4FB and VK4CSD claimed a new Australian record for an SSB contact on 122 GHz — 69.6 kilometers (approximately 43.15 miles).
