Michael, KN4PRE is currently active from Kosovo as Z6/KN4PRE. His QRZ page says:

I’m from the USA, currently working in Eastern Europe. My primary focus with HF lies in QRP NVIS. I was in the military for 15 years, working first as a Radio Teletype Operator (MOS 05C) and then as a Special Forces Communications NCO (MOS 18E). Since then, I’ve worked on P25 networks overseas for the military and the Department of State. My job also provides me the opportunity to work with NATO soldiers in their radio communications missions. My equipment consists of a Yaesu FT-857D (base/static – mainly for SSB), and an Elecraft KX-2 (portable/hasty – CW and data). I use Chameleon’s Tactical Delta Loop (TDL) for static comms, their MPAS for hasty/on the move comms and their Tactical Dipole (TDL) for ALE comms.

Activity has been on FT8 thus far, even working the DX-World Club Station – GS5DX
