nanoVNAs - VE3WI Dave - 2022-07-08 Many of us are hooking up our nanoVNAs to everything and marveling at the neat coloured graphs we get. In a thread on QRZ.com about using a nanoVNA, someone posted this very apt quote from Werner von Siemens (famous German electrical engineer and founder of Siemens Corp.): "Messen ist Wissen, aber messen ohne Wissen ist kein Wissen" ("measurement is knowledge, but measurement without knowledge is not knowledge") 73 Dave, VE3WI RE: nanoVNAs - Rob_Walker - 2022-07-09 The nanoVNA will do Smith Charts which is a valuable tool (calculator). It is great for showing antenna matching problems and the behavior of RF patterns at different frequencies. The Smith Chart can appear a little intimidationg at first glance but well worth the investigation in my opinion. RE: nanoVNAs - VE3WI Dave - 2022-07-09 Agreed, and being able to see them live is a much better learning tool than reading about them in a book. 73 Dave, VE3WI |
