[TenTec] Model 1225 SWR and Wattmeter Kit

[K8JHR]

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.
