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.

I am using the Distance to Fault mode. 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.
