Since the buzz is still there when you power it from a battery,
try removing all cables except power. Does it still buzz?
Is the battery connected to a charger?

I bought a one watt Ramsey FM transmitter to distribute whole house
audio .... it's overkill, I admit, but better too much power than to
little.

I don't don't know a ton about radio tech, so I thought I'd ask you
geniuses for advice.

I am getting a wicked buzz from the transmitter. You can hear it
plainly when I tune an FM receiver to the broadcast frequency when
there is no music being broadast. I called Ramsey, but they weren't the
most helpful (maybe because I'm so non-proficient in radio stuff).

Since my audio source was a computer, I considered the possibility that
there was RF coming out of the PC, or that there was a PC related
ground problem. So I tried using an iPod as the source, powered by
battery.

And to get even more anal about it, I powered the transmitter itself
from a car battery with the iPod attached.

Still the buzz. Arghhh.

Could it be my cabling? what is the absolute best way to insulate the
cables? Where can I buy such superinsulated beasts? I need a stereo
mini plug on one end and left/right rca jacks on the other.

I would be so grateful for advicce!
