[UPDATE]  The correct answer is Martti OH2BH & Ville OH2MM. Photo taken during their DXpedition to Sudan & South Sudan in 1980.

[EARLIER] It’s a new week so here’s another DX Shoebox find courtesy of Jose, EA5BCQ. Do you recognize the operators in the photo, and if so who are they and what / when was the DXpedition?

PS: check back on the previous 30 DX Shoebox publications. Maybe you can add more for future posts?
