Great! That's exactly what I wanted to hear.

"Average" time probably is ~ 3-5 seconds, but on some bands I have to 
use the "Alt" mode to get a reasonable match (< 5:1) and it runs for 8 - 
10 seconds.  I'm loading a random wire against a poor ground (a 40m 
counterpoise).  At this time, I'm just playing with what I have up to 
see what the capabilities are.  I plan on adding more counterpoise wires 
this weekend to improve the situation. I also need to check the length 
of my wires to make sure they're not 1/2 wave on any band.
