Radio in apartment
Welcome to my rig in Stockholm. https://www.qrz.com/db/SA0PEJ
As I live in apartment my equipment need to be small and not distract my wife. I hide the radio in breadbox and put antenna outside on balcony.

Antenna on balcony
Building and simulating antennas and testing with SimNEC and NanoVNA. I use Mac and iPad and my new best friend: the crème brûlée torch 🙂 for assembling my creations in metal.
I am a professional beginner, it is great fun.
Started working with radio design 1985, but did not start with amateur radio until 2022 when I took my certificate.
Mostly interested in radio propagation and digital techniques, I work designing 5G systems as my day work.
Rig
Using IC-705 radio controlled by SDR-Control. Routing audio with Loopback to decode in fldigi (sometimes WSTJ-X). Favorite modes are FT8 to check propagation and Hellschreiber because it is fun.
