Thanks again, Phil. After a lifetime of dogs, we only have cats. They do
their business in their litter box. I have often wondered how the meters in
question stack up against similar priced ones. Are they a cheap meter with
a big mouth? I hear some meters of less quality add forward and reflected
power in their SWR reading.
Good, as always, to hear from you.
