LWDQGS TDM-1911 Automatic Distortion Meter 

For clarification, no instrument on my hobby bench is calibrated. I used to get my IFR-1200 calibrated but haven’t done that this year. What’s the point of paying $400 or$500 for a calibration when I’m not using it or any of this equipment to make money? Not much point in my mind for that anymore. I do run a GPS disciplined oscillator and share that 10mhz reference to everything on my bench that will take it. That does make things consistent…
