Biography

Hi,


I started my HAM activity in high school in Ljubjana in 1976. There I got my first call sign YU3TGT, latter changer to YT3HA, S52HA and S52V.

After Air tehnical academy in Sarajevo, I post graduate bachelor's degree on economy and finish
specialization on management. I have build few memory tuned amplifiers with Russian triodes and tetrodes (GU74b, GU77b, GU78b), just finished liquid cooled SSPA uding 2 pallets BLF188XR, also finished some smaller HAM projects like spectrum analyzer, tracking generator, harmonic converter, frequency meter, storage normalizer, Arduino automatic antenna tuner, digital SWR power meter with 3.5 inch touch display, arduino outomatic antenna switch, wi-fi rotator interface.

For 36 years I was working on the field of communications.

I retired in 2019 at the age of 58. Now I have more time for HAM radio activity and smaller HAM radio projects.

I hope to hear you on the bands.

vy 73, Branko
