: .... To verify the results, I tried entering the .89 velocity factor to get the length of the line, and it kept coming in at a 26.6 foot length -- oh, well. "Oh, well" means you didn't understand something, a problem to be resolved. It is a long time since I used one of these. I assume you are using the Distance to Fault mode. Did you find the first X=0 point to be around 4MHz? If you mistakenly found the first at a higher frequency, it will give a harmonically related result. Owen |

I've tried several frequencies for X=0, and sometimes get the 26.6 foot figure, other times non-sensical answers in the thousands of feet. Bob k5qwg |
