Recently my colleague, Rob PA5RH and I came up with the idea to build an automatic loop tuner. Rob is busy with the software part where I have already started on the mechanical part. As loop, Cellflex 1 1/4 inch Coax cable is used. This has a (copper) outer diameter of +/- 38mm I want…

As I have succesfully built the ATU-100 kit, I decided to go for a beafier ATU kit. Some weeks ago I received a kit from Ali Express. The ATU-1000 Automatic Antenna tuner kit. It is based on the same design of N7DCC, but the board is designed by EU2AV. The same firware is used as…

On friday the 11th of June, there was a lot of good propagation on 10m. Most of the time if there is good propagation is trying to work the N2ROW repeater in New York. Frequency: 29.680MHz Shift: -100KHz CTCSS Tone: 136.5Hz.   Also found a fairly unknow repeater on: Frequency: 29.660MHz Shift: -100KHz CTCSS Tone:…

As the WRTC event draws closer and closer to the end, it’s getting harder and harder to complete everything. Over the past few months I have managed to get most WRTC stations worked on 40m / 20m and 10m. I am very happy that my station works quite well, even with rare conditions at 10m…

Recently I purchased a ATU-100 Antenna tuner kit from Aliexpress. I have purchased this kit because the internal tuner of my IC-7610 has a tuning limit of 150ohms / SWR <3:1 as most internal tuners do. My previous IC-7300 had the tuner modification which extended the tuning limit, so tuning my antenna was no proplem…

My current antenna for 10 and 20m is still my old wire dipole. Construction is a wire Fan Dipole, in some slight inverterd V configuration directed East / West. Due the proper height of the antenna working DX is no problem at all.  

After a period of more than 4 years of being QRT since 2018 due to severe QRM. Since March 2022 I have embraced the amateur radio hobby again 🙂 Even though there is still regular QRM present, it can now be dealt with. I use almost the same setup as before 🙂 Fortunately, I still…
