Thanks, Colin:

I know one of those persistent stories about SWR is that quote inexpensive 
meters add forward and reflected power.  I did test on a couple of antenna 
systems matched with an external tuner to 1.0 to 1.  Now wonder what price 
defines inexpensive!  Thanks.  I am having fun with the new toy.
