Mike,
If you think you are under the radar you are sorely mistaken. You
admitted on a public list that gear you use is not certified.

Yeah, but your over the limit! :)
Heck why go after a 3000 little guys when you can go after one big guy.
They've been selling unlicensed amplifiers and uncertified systems for
as long as I can remember. Heck, talk about posting a message on this
list, what about having a full blown catalog online advertizing US sales
with prices next to them?
I believe they should have spent the 3 or 4 g's to get the systems they
sell certified before they sold them.
They make millions easily selling uncertified gear and it's not a secret.
Ohh, I feel another rant coming on.. .George, you better take a chill pill
:)
While this is a peripheral issue with "certification", I have made
suggestions to the FCC about certification of individual components. I
kinda doubt it's going to happen. At least not soon, regulators are
notorious for not liking change, since it makes things less tidy for them.
I buy computer components... motherboad, processors, video cards, and so
on... And tires, and car parts, and actually quite a few other things that
have technical performance reviews by people who have tested things.
I WISH that manufacturers could certify components, because then we'd have
published real-wolrd performance graphs and charts to use for comparison
when we buy things. Just "certified" really isn't "good enough" in my
view. I recall that a good number of years ago, there was a hack for a
linksys AP that turned up the power. Someone used an SA on it and found
that when you did it, the output became incredibly dirty.
Certified or not, I would like to know that what I buy is "clean" rf-wise.
Low OOB emissions. Minimal out of channel emissions, selective recievers
that reject adjacent channel noise. Really comparable specs for dealing
with noise and S/N ratios, etc.
I really dislike not knowing those things about what I buy. And, due to
the way certification works, certification has almost no meaning when it
comes to those important RF characteristics. Early on in my investigating
the wireless business, lots of people were testing new products and
publishing the results. I dont' see ANY of that going on anymore.
Wrong. Certification DOES test for out of band emissions; it also tests
for out of channel emissions. It does not test for receiver selectivity
because that is not a characteristic that will mess up the band. Part 15
certification deals primarily with dirty transmitted signals, not poor
receivers.

Any suggestions to motivate manufacturers?
