Hi Jim,

As of yet, I haven't done the range check.  I am still running it on 1 watt 
because it is fine at that level.  Some day when I get real brave, I'll put 
it up to 7 watts and walk around the neighborhood to see just what it can 
do.  Who know, I might even hook it up to my Channel Master scanner antenna 
on high power for a short time to see if it actually reaches to the tenths 
of miles in range--though I must be careful about the match on that older 
antenna.  I am running it at 87.5 mHz--the lowest frequency that most FM 
receivers will receive so as to not arouse any outside interest <laugh>.

Hey, that's great.  Have you done a range check to see how far
you can hear your signal? Jim WA6EKS

Hi Group,

Thanks for all the suggestions.  I have pretty much solved the
issue by
moving the transmitter as far away from the computer and speakers
as
possible.  I think I might have to get it a bit further because
at times I
still hear a bit of hum, but at least about 90% of the issue is
gone.  I
have a 6 foot audio cable.  Maybe I should get 1 a bit
longer--perhaps 8 or
10 feet.

Pretty sure there is no conflict between WiFi and the FM
transmitter.  I would be surprised if that was the case.  Jim

it might be picking up the pulsations from your WIFI setup.  try
temporarily turning that off and see if it goes away.
if it does, try using the transmitter further away from your
modem? router?

     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.
