Main reason is that the diode detector types of VSWR Meters are very
inaccurate when any VSWR is present

Also I have found that running PA's at 90% gives a much cleaner output
(Usually) so I need a meter that will give reasonable accuracy when making
these adjustments.

Some cheapo VHF VSWR meters are so inaccurate as to be useless.
For Bird -- buy the appropriate slug -- slugs are very inexpensive on the
used market.
Not E-BAy -- hi hi

And Mil Surplus thru line meters are very cheap on the surplus market, Less
than new diode detector types.

Why would a ham operator have a need for such accuracy ?
Isn't consistency enough ? For ensurance of not exceeding
the power output for those who want to equal the max then
a scope would be the way to go. For those that build then
there is a need for accuracy and bragging rights are fully
earned. Seems like this falls into the same catagory of
