Hi Ron, I have the same problem. I haven't tried my own idea
yet, but I would recommend locating the transmitter farther away
from your computer speakers and use a long coax feedline to
connect it to your computer. Also, you could try rapping the
audio feedline through some of those fehrite loops that will
filter out RF. Sorry I can't find the right spelling of fehrite
in my spell checker. I think if you get the transmitter 15 to 20
feet away from your computer it should not interfere with the
computer speakers which are notoriously good at picking up RF. I
get hum in my computer speakers from my VHF antenna mounted
probably 35 to 45 feet away up in the clear when I transmit using
high power on my Kenwood TMV71A. 73, Jim

Subject: FM Transmitter Issues And Questions
Hi list,
Since this is one of the lists where I got information about an
FM
transmitter for feeding audio from my computer to FM receivers
through out
my house and property, I thought I would inquire here again.
I have purchased the Sansonic FM transmitter that someone
referenced on this
list a few months ago. It does a real nice job with meeting my
requirements
of clear and clean signals through out my property. However, I
have run
into one problem. I have the transmitter fairly close to the
computer from
which I am running the audio. It is about 4 feet away from the
computer. I
am getting a pulsating hum through the computer speakers when the
transmitter is operating. The transmitter runs from 1 to 7
watts. In light
of the issue, I don't dare put the power any higher than 1
watt--and I
really don't need to anyway.
What can I do to solve this problem? Any help would be greatly
appreciated.
