But wouldn't the CB device op be required to make changes? He's the one
causing the interferance. My memory of such things is quite dusty.

The part 15 device is the bottom of the food chain.
It is required to accept any and all interference, including that which may
cause undesired operation.

This assumes that the other device is either part 15, or unmodified CB, or
commercial licenced radio (unmodified), or ham radio operating in-spec.

If I read them right, a modded CB, or one with an amp, or a ham radio that
was operating out of spec, would be given the burden of cleaning up the
problem.
If you're operating illegally, then you go below the part 15 devices.

Modded or not, I *think* it's up to the radio operator NOT to interfere with
his/her neighbors.

I look at it this way;
If your cordless phone was making my garage door go up and down all night,
I'd expect YOU to remedy that situation.

I had a situation once where I was broadcasting through a next door
neighbors, well, let's just say a "type of piano you find in a church"
because I can't think of how to word it without it coming out wrong:-) That
was about 20 years ago when I was running 750 watts through stacked
moonraker IV's. I tried installing filters every where I could plug one in
but to no avail. So I stopped running the linear and all was well....it was
just a cheap splatter box anyway. We moved and I sold everything.

We actually just stopped in to see them a few months ago and she still has
and plays that "type of piano you find in a church" :-)

Well Don, in a Good Neighbor type of way, you would think that the
owner/operator of the transmitting equipment would do "the right
thing" and resolve the interference issue. I agree that the operator
should take reasonable effort to do what they can. Example, a
neighbor nearby complained that my Amateur gear (unamplified, no more
than 70 watts to the antenna) was interfering with their TV. I put a
low-pass filter on my antenna feedline and haven't heard a word from
them since. Now granted, I'm operating under Part 97, and they are
owners of Part 15 devices, but since they live two houses down, I
figure maybe someone else might be hearing my SSB signal on their TV.
Turns out later that they're using a satellite system and their
internal wiring is point to point with SPEAKER WIRE!

Trust me. If the low-pass filter didn't do the job, I'd have sent
them packing and looking for other solutions. I made an effort.
Possibly a token effort, but still an effort beyond what the law
required.

Then again, unlike you, I tend to operate legally, and therefore I
have very few interference complaints and if I DID have any other
complaints, would be 100% legal in telling the owner of the Part 15
device that they need to look at THEIR installation first, THEN come
talk to me...

I've seen lo-pass and high-pass have -no effect- because of fundamentals
and cheap home electronics. In the end you still have to deal with a ****ed
of neighbor.

HA!..that frigging church pianne' doubles as a field strength meter!

Better re-read that part 15 notice that came with it.

The sad fact is that a lot of these devices are made, with practically no
effort to immunity.
They lack even minimal shielding, have very poorly chosen 1st/2nd IF
frequencies, with no image rejection, and rely on the most trivial encoding
systems, all to save nickles.


http://www.arrl.org/tis/info/part15.html#Scope

"To help emphasize the secondary status of all devices operated under Part
15, the rules stipulate that the devices must not cause harmful interference
to other radio services and must accept any interference caused by the legal
operation of other radio services."
