QSL via:
My story with radiowaves started with my first CB radio Allamat 296 and a small magnet-mount antenna. I have made a few local QSOs and then definitely fell in love with radio signals. I have started with some attempts at receiving SAQ Grimmeton, with SDR receivers as SWL and I obtained my HAM radio Novice license in May of 2017 which I upgraded to CEPT E / HAREC in October 2018.
I'm a proud member of the radio club Omega OM3KFF and you can hear my voice during HF contesting season on 160m, 80m,40m, and 20m bands.
Building of my home QTH is still in progress but I have a small compromise short random-wire antenna with UNUN 1:4:9:16 and random wire of 6.5m length from my window to my balcony. It works somehow on 6m, 10m, 12m, 17m, 20m, 30m, 40m, and 60m. Even with this short "antenna", I made a lot of QSO on FT8 (SSB as well) including JA, NA, and SA stations and plenty of DIGI or SSB QSO with EU stations.
I'm QRV on 4m, 2m/70cm DIGI, and SSB with QRP power with my mini balcony antennas and with some antenna experiments. I'm currently QRV on 4m with my homemade balcony Inv-V.
You can hear my voice on SOTA activities, mostly on 2m FM but when it is possible I'm QRV on 40m / 20m as well with a power of 20W from Xiegu G90.
I have been interested in electronics and technology since my early childhood. Therefore I'm a fan of DIY stuff, mostly antennas, small equipment, and MCU-related things like Arduino, Raspberry Pi, ARM, and STM32.
I'm a fan of computer programming, open-source technologies, Linux, and server stuff.
My equipment
- Yaesu FT-991A + LDG-AT100proII automatic antenna tuner (an excellent piece of equipment)
- QRP transverters 4m, 2m and 70cm by Serge UT5JCW
- Baofeng UV5R handheld, Zastone ZX6 mini UHF handheld
- Yaesu FT-60E handheld + Slim-Jim (Nelson Antennas) or dual band N9TAX Slim-Jim
- Xiegu G90 + homebrew linked dipole for 80/17m for SOTA+ homebrew EFHW for 40m, 20m, 15m for SOTA
- (tr)uSDX QRP 5W by Manuel DL2MAN
- Retevis RT3 UHF DMR handheld, Radioddity GD-77 VHF/UHF DMR handheld
- Yaesu FT-8900 mobile 6m/10m/VHF/UHF + homebrew outdoor slim-jim for 2m/70cm
- Raspberry Pi 2 DV MEGA-based PI-STAR DMR/YSF hotspot
- Raspberry Pi 2 WSPR beacon + QRPLabs filters
- Homebrew QRP RX/TX switch for RSP1A SDR used mostly for VHF operations
- Homebrew QRM Eliminator X-phase
- Homebrew DIGI interface for my backup radio Yaesu FT891
- plenty of other stuff, Nano VNA, FoxDelta analyzer, baluns, SWL antennas, antenna switches, chargers, mini whips, SDR devices...
