That's another good idea, moving the antenna itself away from the 
transmitter, but you will encounter some signal loss between the 
transmitter and antenna depending on how long your coax is.  Jim

Build a quarter wave antenna and move it away from the computer.  
I'd
guess your antenna is right on the transmitter..

    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.
