Does anyone have a web-site or youtube that goes through the set-up on using the F V2 for checking Coax lengths. The new one I have does not show the correct length, example a known 15.24m / 50ft coax comes up over 3 times that. Thinking maybe velocity-factor inputs. No help. The H4 VNA I have is spot on with the numbers. Any help would be grateful. Thanks
