Welcome, well, I'm original from the "Old World", out of the middle of Europe-AUSTRIA.

I started Ham-radio back in Vienna, Austria in the early 60's. After settling in the USA, in the late 70's, I got interested in Ham radio, again.
I enjoy digital-communication (PSK31, RTTY, etc.) I'm running an APRS-WX station and a stand alone ECHO_LINK Node # 273835 (145.650 MHz).
Hope to hear you on the air, good DX and 73 de KF4KUL (Udo)

Other interests are, Photography and Road racing (Le Mans-type), some times F1 ... and enjoying life.
