Ed, *1)* You've got a typo in your callsign: it should be KC1D*YK* (ROKBL!) *2)* In terms of verifying the fundamental measuring impedance of the nanoVNA, that's a lot trickier. The essence of most

Hi just spent a UK windy afternoon confined to my radio 'shack' , so decided to upgrade the screening on my 'basic' clone nanoVNA to see if the INPUT 'noise' could be reduced. I made the screens out

Thank you very much DiSlord for your help and work. I will install this file this afternoon and inform you for the result. Regards, Rudi

After searching for this component numbering, i found nothing at LCSC. I've done many frequency measurements and? had a great drift with temperature. May be it's not a TCXO but a XO with +/- 100 ppm
