Hello everyone and welcome to my ham radio web site.

IU3JSX here, operator name Marco.

I’m an electronics engineer and I always had a huge passion for radio. I got my license in October 2017.

My current setup is:

  • Homebrew delta loop following this project: http://www.dj0ip.de/my-favorite-antennas/my-favorite-40m/
    • Update 2019-06-18. I decided to rotate the loop and lay it horizontally, making it a Skywire loop, to test NVIS operation. It currently works very good at 40m and “workable” at 80m, getting better at harmonics, especially 20m and 18m. More details about this new setup as usage history becomes relevant.
  • Old Yaesu FT-101E, which I got for peanuts but it works and served me good for my first experience in HF bands (80m, 40m, 20m, 15m, 10m). I also plan on getting skilled in servicing the FT-101 and similar rigs. The audio coming out from it is simply spectacular and the beauty of operating an analog VFO knob, calibrarting it, keeping eye on vu meters is somehing everyone should try at least once!
  • Kenwood TS-570D. This is my current main rig.
  • Antenna tuner – MFJ 948 (for the FT101).
  • SDRPlay RSP 2 Pro
  • SWL antenna “Scan king 1500”
  • Raspberry PI 3 to run OpenWebRX, WSPR reporting and other cool stuff
  • My PC – MacBook Pro 2015
  • Audio board used: Lexicon Alpha Studio, 24 bit 48 KHz low latency audio interface.
  • Home made audio adapter between the audio board and the FT-101, which I use for digital modes. Takes PTT signal from the right channel output which FLDIGI feeds with a 1 KHz sine wave. Derived from http://w1hkj.com/FldigiHelp-3.21/html/w5zit_rt_channel_page.html.
    Also added a manual PTT push button to use for SSB QSO, in conjunction with audio software like Reaper, allows me to¬† experiment on mic filtering and processing, and also to use any audio headphones, headsets….

I’ve always had a big passion for electronincs and radio! Currently I’m struggling to find time to do all the things I’d like to do in ham radio, but I’ll soon add 2m and 70cm equipment.
