[TowerTalk] FA-VA5 question

[David Gilbert]

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
