Hello, first post here.
I've built the TDR with the 74ac14 as shown at wae2w yt video (
)
It seems to work fine, but when it comes to test it with a coax 5.55 meters long, I read 72 nS, which according to the average velocity factor of 0.659 it results in 6.24 meters. Is this an error in the Velocity Factor? (I have no way to find out the real VF, all I can read is "Noisless" and a logo)
Thank yhou
