The Yaesu FT897D has a visual zerobeat indicator when the rig is running CW. The LED will light up when you are exact (or atleast close) on frequency with the transmitting party. Having a little room left on the extension PCB in my uBitx, I thought it would be a nice adition to have one based on a LM567 tone detector.
A few weeks a go I found a stock of suction cups towel holders in my workshop (proberbly bought them years ago) and looking at them the idea came to build a 2m quad antenna that could stick to a window with these suction cups. Continuereading.
