Antennas and RF
Building, tuning, measuring and understanding why something works remains one of the best parts of the hobby.

Amateur radio
The world became larger when it started coming out of a speaker.
As a child I listened to shortwave stations in other languages and imagined cultures, music, food and people far beyond my surroundings. My Brazilian amateur radio license came in 2009; curiosity about radio had been there for years.
01 / Origin
Radio has always been about people too.
What attracted me was the possibility of talking to someone far away who shared the same interest. Today I make fewer random contacts and enjoy nets, conversations that grow over time and friendships that begin on the air.
Radio remains a doorway to accents, places, cultures and different experiences. Technology matters, but without people on the other side it loses much of its meaning.
02 / Tradition and digital
There is no need to choose a side.
I take part in CW activities and deeply respect classic techniques. At the same time, I enjoy DMR, D-Star, YSF/C4FM, APRS, LoRa, satellites and other digital forms of communication.
For me, preserving amateur radio history and experimenting with new technology are not opposing goals. The interesting part is keeping room for both.
03 / What keeps me here
The process is often better than the result.
Digital modes
Protocols, networks and new ways of covering large areas keep radio connected to contemporary experimentation.
Community
Shared information and attention to newcomers matter more than using experience as a position of superiority.
Emergency
Technical preparation matters, but willingness to help matters too. Emergency communication requires training, cooperation and responsibility.
04 / Experimentation
Equipment changes. Curiosity stays.
I do not keep a fixed equipment list because I am always testing something. I prefer to talk about what remains: radio, electronics, antennas, software, digital modes and communication independent of conventional commercial infrastructure when that becomes necessary.
I do not present myself as an RF guru. I have years of practice and plenty left to learn, which is exactly one of the reasons to continue.
