KDDR Oakes, ND 1220 kHz and KDAK Carrington, ND 1600 kHz both were captured on the same day during ENOX19. They both verified also on the same day - but in two different emails!
Actually KDDR was picked up several times on ENOX19. KDAK only once but luckily on the top of the hour with a legal ID. After these two QSLs I'm still missing KOVC 1490 - a third station in the Dakota Country network. Hopefully I'll come across KOVC one of my unopened files from this great MN/ND opening on ENOX19.
