Hello all you friendly helpers,
Does anybody know what causes AM Radio Interference with Desktop
Systems.
I have tried the Belkin EFI & RFI filter. It does not seem to make any
difference. As soon as I boot up my desktop, the AM Radio reception in
our house goes grazy.
I don't have this problem with our Notebook!!
Much appreciciate any feedback.

What Belkin filter? Did you speculate that a Belkin
protector is a filter?

Now from desktop systems is often due to clones built on
price - therefore missing essential functions such as the
required RFI filters in power supply and on motherboard.
There is no plug-in solution to your problem. Your problem is
solved at its source. For example, what is that power
supply. Does it even specifically claim to meet FCC
requirements? If not, start asking yourself what other
essential functions are also missing inside that computer.

AM radio is one good diagnostic tool it identify computers
that are missing essential functions. A symptom that should
only have you asking more embarrassing questions.

In many situations, the PC case is not built to provide strong shielding.
The power supply and any connection that goes thru the case from or to an
external device are also suspect. How close is the AM radio, and how
distant are the stations? Does the branch circuit feeding the PC have a good
safety ground? Is the AM radio on the same branch circuit?
In most situations the noise from the PC can be reduced, but not eliminated.

Hi Tom,
Thank you very much for great response.
The Belkin is a small plug in surge surpressor with filters. Of course
it didn't work.
I will have to find out if there are any computers on the market, free
of this problem.
Thanks again
Manfred

Hi Chuck,
Thank you very much for your great response.
The interference is throughout the entire house. Regardless where I
plug in the radio. I think it carries through the electrical system.
The house is only 2 years old. Everything is properly grounded
I begin to wonder if there are any PC's on the market, free of this
problem.
Thanks again
Have a great day
Manfred

That filter inside the Belkin exists. And then we apply
numbers to that filter. A numbers so small that the filter
really does not exist. Many protector manufacturers make
claims without numbers - so that you will believe myths. That
Belkin also claims ineffective surge suppression AND can even
contribute to damage of the adjacent hardware. But again,
notice the missing numbers.

Any filter that is going to work on a power cord is already
inside the power supply. Filtering all but required by FCC
and by so many other nation's regulations. Some power
supplies are being marketed to technically naive computer
assemblers who hype how much cheaper their computers cost. The
AM radio should identify some such products.

Some computer assemblers buy only on watts and price. To
sell a power supply at less than $60 retail, that filter is
but another essential function routinely forgotten in cheaper
power supplies. Same filter that the Belkin also does not
(for all practical purposes) provide. Belkin 'power
protection' products also may deceive by forgetting to provide
numbers and other significant facts. But then if that Belkin
filter exists, how many dBs of filtering for each frequency?
Why did they not provide those spec numbers? Because they
don't provide any useful filtering.

Properly manufactured PC should not cause the problems you
are suffering. It is required even by FCC regulations. A PC
can only interfere with an AM station that is already very
weak.

In the USA the FCC certifies computers and other devices
under FCC Part 15. You'll see a label for all legally
imported and sold equipment. But there are two standards,
part A and B. Part A applies to office equipment and the
standard allows more RF emissions since office are
considered industrial zones with a higher allowed level if
interference.

The use of FCC Part 15A equipment in residential areas is no
fully legal. If your neighbors report interference the FCC
will make you replace the equipment or take other action to
stop the interference with others use of their equipment.

The reason the ;laptop doesn't cause RFI is that it is Class
B, look on the bottom and you'll see the label.

The case on the computer has to be a Faraday cage,
electrically closed to keep the RF energy inside the
computer. If it has bad wires, poor connections and
especially a plastic window so you can see all those lights
and fancy fans, you have a perfect RF transmitter.

If you have to have windows and such, then you need to have
a grounded screen (like in the door of a microwave oven) to
contain the RFI.

As an amateur radio op using pc for digital ops I have found most of
the rf noise comes from the CRT display. I switched to LCD and noise
now almost completely gone. I had tried ferrites on CRT power and vga
cable before with poor results.
However if you have a plastic case, see through, etc. all bets are
off.

Boot up your computer with your monitor turned off. Find out whether the
problem is with the monitor or the computer.

I found my AM radio interference problem to be my power supply. Checking further, even some
expensive power supplies provide AM interference. I settled on an A open, and that fixed my
interference problem.

Check FCC certification (for all hardware/systems) to be FCC
Part 15 Class B to reduce RFI to within limits.
