Gee... Sorta condescending and demeaning. And not particularly helpful.
I often forget ham radio is only for experts with careers in
electrical engineering - the rest of us hobbyists are merely tolerated,
perhaps only because we buy stuff and keep prices down.
OK, I read the N8LP web page and, I am sorry because I do not see where
it addresses Carl's point about some meters being less accurate if the
load varies from 50 ohms, or how the LP-100 is immune from that problem.
Perhaps someone can explain this on the E-brand reflector... As far as
I can see, both units might be affected similarly as they will be used
exactly in the same way. I suppose I missed it, but I tried.
Sidebar: The web page says the LP-100 is the only meter with
simultaneous bar graphs for both power and SWR... but that is not true,
the W2 has this feature, also. Go figure... ;-)
So, OK, I am getting familiar with the old fifth grade brush off answer,
"...someday you will understand." I appreciate Carl's reply, but I
still don't know how the one meter is more immune than the other. So
far, Bob is the only one to offer a solution within the specifications
and budget stated.
So, never mind, I will drive on, reading my ARRL Handbook, slowly, page
by page, and wait for the great epiphany everyone else must have already
experienced. But I won't buy something just because somebody says I
should.
And while I am at it, this whole "contest" thing seems a bit overblown.
How many contests have been lost because the the operator could not
determine amplifier power with sufficient accuracy? Would a fraction of
a dB more oomph really make all the difference? All this talk about
contesting... I would love to know everyone's actual contest record! I
wonder how many are really in the race. Heck, a lot of TT guys
disparage ICOM radios, but K3LR has a shack full of them. So who can
you trust?
Thanks for the courtesy of a reply, and I am sorry I don't get it.
Happy days.

Would I really benefit from spending more on the LP-100? That is the
real question. Would it really be worth twice the cost? What would
I do with the more accurate information it provides? Do I really need
more than a close approximation? If so, what would it do for me?
You could study N8LP's web page. Click on the LP100A link. It's worth it
to me if it lets me run closer to legal limit in a contest, or when
calling DX. 1.5:1 SWR causes significant error in the power measurement.
You could learn more about how transmission lines work.
