Our mission at ClearSkyRF is to provide a low-threshold experimental environment that unleashes new forms of creativity and scientific insight.
Using what’s at hand and making the most of your surroundings is critical to gaining quick insights without the high price tag associated with formal experimentation.
In this series, I share documentation from my past experiments — hopefully to spark ideas and conversations.
Here’s an 80m HF beacon (CW and RTTY only) I made a while back:
Mitsubishi RD16HHF power transistors are my favorite for 6m and below. I tried with BD13x before, assuming 80m is so low in frequency that I might get away with it, but the results were just not good enough.
10dB down on the third harmonic without output filters isn’t bad:
