    Just a warning for people thinking about getting into #microwave #amateurradio -- it's a labyrinth of hobbies, knowledge, and equipment. Precision machining, stripline circuits, strange semiconductors (IMPATT diode amplifier, anyone?), exotic electron tubes (which can and will kill you one way or another: xrays, high voltage, beryllium oxide), metrology, physics, too many wrong hex keys, DIY, repair of vintage surplus gear, morse code (modulation is sheer luxury), scouring ebay, haunting electronics store surplus sections, and poring through poorly scanned service manuals from defunct startups.

      @jmorris heh radio astronomy was my gateway to amateur radio. I’ve still got a WR650 waveguide cut from an olive oil can waiting to be attached to a 1:3 scale insulation replica of the Ewen-Purcell horn. I got stuck on my digital chain, parked it, used the parts for a SATNOGS station, ran into trouble on my RF analogue chain, started researching antenna design, and before you know it I was at the ham club. Oops.
