Ham Member Lookups: 6526


I received a general class license on July 19, 2010. I upgraded to extra class on July, 2012 and obtained my vanity call sign (AC3SS, formerly KB3UYY) on September 4, 2012. My ham shack consists of a KX3, a IC-706 MKGII, 2 Kenwoods TS-820s, an Ameritron AL-80 linear amplifier, a Swan 5002, and a couple of 2m radios. My antenna farm consists of a ground-mounted Hustler 7BTV vertical for 80, 40, 20, 17, 15, 12, and 10m with ground radials, a 2m/70cm GP1 vertical, and an Alpha-Delta paralell dipole for 20, 15, and 10 m mounted low (25 feet) between two trees in my backyard (stealthy mounted to prevent clashes with neighbors and HOA!).

More recently I acquired 2 fusion radios, a FTM-400 and a FT-2DR and a TYT 380. I am enjoying operating on C4FM and DMR digital voice modes. For mobile operation I use a DV4mini hot spot and the FTM-400 to get on the available internet nodes.

I am an oceanographer by training and apart from being a ham radio aficionado my other hobbies are ciclyng and astronomy. I was born in Sao Paulo, Brazil, where I lived for 37 years. I immigrated to the US in 1983 where I established residence, first in Boston, Massachusetts, and now in Maryland. My XYL is from Boston. We lived in Brazil for almost 4 years before returning to the US. Besides English, I speak Portuguese, my native language, Italian as the son of Italian immigrants, and Spanish. I often enjoy QSOs with fellow ham operators from USA, Brazil, Italy (in Italian some times), and all over the world. One of the best advantages of being an amateur radio operator is to make friends over the air waves from all corners of the world. I quite often do QSOs via EchoLink from my iphone.

I have included several photos from travels around the world and from our own neck of the woods. Enjoy and happy QSOs.

Sergio, AC3SS
