Well, thanks, Mike.

I guess like anything, readings with these devices are relative.

The power meter in the TS590 seems much more consistent and stable, so I 
will continue to use that one, and the TW1 as a rough way to double-check 
things if needed.

Prior to my having the TS590, I had to rely on the TW1, and at least it got 
me through to this point, without letting the smoke out of anything, so I am 
thankful to have had it.

Maybe someday, if I can get my hands on one of those RF Applications units, 
I'll give that one  a try too.
