Dave,
Send me the FA-VA5 complex impedance measurements for these three
frequencies taken from each end of the line (six readings):
5 MHz, 10 Mhz, 15 MHz
If I can't determine where the faults are with those measurements I
should at least be able to determine which better frequencies to use and
then I'll ask you for those measurements.
73,
Dave AB7E

I have one of these which I use to check SWR and measure component values.
I love it. I know it is capable of doing more. I just haven't had a need
to use it any other way. What I am wondering is, will the thing act as a
TDR?
I have a 200 foot run of half inch Superflex cable buried in a PVC pipe.
Thanks to a recent lightning strike, It measures shorted at one end of the
run and open at the other. If I could get some Idea where the problem is,
perhaps I could dig it up and repair it without trying to pull and replace
it. A fault like this implies to me that there is a clean break somewhere
and a short somewhere else. With a TDR, I could find the break and repair
it, then find the short.
Any other thoughts? Sure would be nice if I could get this repaired before
winter sets in.
Thanks & 73,
Dave, K4TO
ps -- I know there is a manual for this. Please don't suggest that I read
it. I have nine pieces of equipment to repair and I am up to my ears in
alligators!
