My name is Filip. I was born in Mokotów and I’ve lived here all my life — and it’s from here that I work the amateur bands under the callsign SQ5CBA. I’ve been drawn to radio for a long time; I obtained my radio licence in 2026, so I’m a new operator on the bands — all the more hungry for the airwaves.
I’m into radio contacts, CW telegraphy, building and tuning antennas, and everything that happens between the transmitter and the ionosphere. Day to day I operate on the amateur VHF and UHF bands — from analogue FM via repeaters to the digital modes C4FM and D-STAR — and I also venture into the microwave 23 cm band.
This site is my radio calling card and a place for projects — including my own Morse code trainer that I use to learn and reinforce CW characters. I’m open to new friendships and continuous learning — if you hear me on the band, don’t hesitate to call. See you on the air, 73!
