This year we wanted to seriously compete in CQWW CW from ED1R contest station. While the station is equipped reasonably on all bands with Yagis and verticals, there were no dedicated receiving antennas available - yet. Out of my former contest participations from other stations I know that when it come down to winning a CQWW, dedicated receiving antennas are a must have. Beverages provide great directivity and reduce the EU clutter significantly.
Today, I had the possibility to measure the performance of the well known ICE bandpass filters. Read more about the measurement results.
Lately I needed a 3dB splitter for a HF (1…30MHz) measurement project. Instead of buying me a splitter, I decided to build it on my own. After measuring the performance I am satisfied with the result.
