Sounds like a cable with to thin screening perhaps?  Many of the cables you get 
nowadays have very thin screening.

Did you consider trying a clean box or hum filter like you would use with 
guitar amplifiers?
You run it into your mixer and plug your radio into that! Art and Behrenger 
make them. I was going to say you could get an isolation ground loop filter 
from Radio Shack but they aren't in business any more, and I doubt most of the 
sales people wouldn't know what you are talking about.

Thanks.  I often have to move the wires around, which is why I thought a new 
wire might solve the trick.  However, I can't get a completely non-existent 
buzz without holding the middle of it up in the air, which obviously isn't 
feasible.  I just find it odd that it does it with the digital radio but not 
with the iPhone, as they're both digital appliances and I don't move the wire 
when swapping over devices (obviously I have to take the jack out of one and 
put it in the other but the cable itself stays flat rather than up in the air 
while attached to the iPhone and it remains in the same position).  Is it 
possible that the iPhone is simply better designed for this sort of thing than 
both of my other devices and, although I appreciate that it's probably quite 
technical, I'd be grateful for any info on how to identify suitable equipment 
for the future if that's the case.
