[Elecraft] K3 KAT3 Antenna Tuner Tutorial

[KM5Q]

Here's another question:  I have a dipole with 200 feet of window-line  
feed. It works great with the ATU.  When it's wet, I have to re-tune,  
then it's fine again.

I've tuned it at lots of spots in some favorite bands during dry  
weather (most of the time in New Mexico). But on a rainy day, I end up  
retuning frequencies here and there. Next sunny day, does the system  
detune me when I run into a previously "wet-tuned" segment?

Oddly, I haven't observed this, but I don't understand why.
