A 2200-meter low pass filter to help buffer the modified MF Solutions converter

– Posted in: 2200 Meters

While performing some off-air tests with the modified MF Solutions converter it became apparent that any variations in a load impedance were going to result in potential variations in the on-board output filter network.  This would likely cause matching issues with the FET and you can probably imagine how it could all spiral downhill from [...]

Coil is finished, installed and resonated…

Shorter days and colder weather are rapidly approaching so no time like the present. For starters, winding the coil just about killed me.  #10 AWG solid wire is challenging [...]
