The picture is of Nancy (XYL) and me in Chicago in 2010.

I am a RF/hardware/systems engineer. I design ablation generators at Atrial Fibrillation (AF) Solutions, Medtronic Cardiac Rhythm & Heart Failure, Mounds View, MN.

I was originally licensed as WN0DSJ in Feb 1971. I have been K0SF since 1977. I enjoy home-brewing, DXing, and some contesting. I paper QSLL 100%. I am also on EQSL.

My most recent DX QSL mailing was August 30th, 2016. If you want a QSL card and you're in a hurry, just request one via email; no QSL is necessary. As long as you're in the log, I will mail it out (US direct, DX via the ARRL outgoing QSL bureau). Please do not send $, stamps or IRCs.

73, Steve, K0SF
