Have you checked for RF noise on an HF receiver? I would hate to see

No, I sure haven't, Doug. Mine's reconditioning the 6-year-old diesel
starting battery in my restored 1973 Mercedes 220D antique car,
tonight. I'll check it, when I can.

It can't be any noisier than that damned dual 10A Guest under the aft
cabin bunk in Lionheart. It's 20 over S9 across the HF bands on the
M802/AT140/backstay. Damned thing makes more noise than an electric
drill and VERY wideband!

Maybe you ought to rat them out to the FCC. Shouldn't it be Class B, or
about as noisy as a PC?

Not made for use in the home, where the FCC really cares, I doubt it
comes under Class B.

Is it just me or did the US and UK just capture 1/3

At the least it has to be class A. And I bet pleasure boats would be
construed as class B.

If so, Adler-Barbour solid state fridge will never pass. Just listen
to the pulses on Marine VHF Channel 16....dammit....

An Ugly American personified...just the kind of low-brain output that
enrages those in less developed nations and incites them to attack us.

LOL. Larry's comment is definitely the funniest one I've read today.
However, I didn't realize how funny it was until I saw that Harry took it
seriously.

Larry is serious. You don't know Larry very well. He's five beers short
of a six pack.

Not to mention your 'favorite' Noland multiplexer.... They even admitted to
me once, that they did not have any kind of approval (FCC, CE)

There's a source of information, guys. Meindert, what are the FCC
radiation requirements for this boat electronics? Are these items
required to pass FCC's consumer radiation requirements? Is Norland
violating the law?

My contention is marine electronics isn't covered, otherwise we'd have
a data system that's shielded, not the stupid NMEA-0183 with
unshielded connections screwed down helter-skelter balanced and
unbalanced any old way you builders want to do it with wires hanging
out, radiating like hell. Is this the TRUTH?

According to FCC Part 15, a class B digital device is:
---QQQ---
A digital device that is marketed for use in a residential environment
notwithstanding use in commercial, business and industrial environments.
Examples of such devices include, but are not limited to, personal
computers, calculators, and similar electronic devices that are marketed for
use by the general public. Note: The responsible party may also qualify a
device intended to be marketed in a commercial, business or industrial
environment as a Class B device, and in fact is encouraged to do so,
provided the device complies with the technical specifications for a Class B
digital device. In the event that a particular type of device has been found
to repeatedly cause harmful
interference to radio communications, the Commission may classify such a
digital device as a Class B
digital device, regardless of its intended use.
---UQUQ---

Navigation electronics fall in the category of "digital devices marketed for
use by the general public". For professional use, there are even more
stringent standards (IEC945).

And it is my understanding that FCC approval or compliance is mandatory.
When I export to the US and ship with Fedex, they ant me to fill out a form,
stating that the my multiplexers comply with FCC Part 15 class B. Otherwise
they (Fedex, being the importer) can be held liable.
So you might think Noland is violating the law here. They are for sure with
the units they export to Europe, because they have no CE marking.

The limits for radiated emmission for class B devices a
30 - 88MHz: 100uV/m
88 - 216MHz: 150uV/m
216 - 960MHz: 200uV/m
Above 960MHz: 500uV/m
All measured at 3 meters distance.
