   A fellow #hamradio operator and electronics enthusiast brought me a vintage X-Band power sensor, thanks OZ1ETE 🙂

   It has a super sensitive NTC Thermistor, a tiny spherical bead, encapsulated inside a small glass tube. It’s by far the most sensitive Thermistor I’ve ever seen, just holding your hand in front of the waveguide flange, not actually covering it, will make it change slightly.
