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.
