Been a ham since 1992, when I was 13 years old, with callsign PU1WLF.

Got my current callsign, PY1NB at 1996, age 16.

Currently active on HF from 160 to 10m, with greater interest on low bands. Active on both CW and SSB.

My main interests are DXing and technical aspects of the hobby. I like modeling and assembling antennas, amplifiers and miscelaneous station gadgets.

Started the website www.dxwatch.com on 2004, a web based dx cluster.

Since 2006 I host PR1T contest station at my QTH. Funny thing is that building a contest station lead us to all kind of weird problems and creative solutions, and to a much better understanding of RF "phenomena".

Started the reverse beacon network project among N4ZR on early 2008.

Operated on 2009 on PT1R (sa-079) and ZY0T dxpeditions.
