AM Radio and power supplies...

Hi all,

I have a simple 4 axis unit, 4 Gecko's, power supply and such.

My problem is that the radio whistles and whines when the Gecko's are
connected.

The pitch raises and lowers over a minute or less.

I was wondering if I am just stuck with the problem or if there was
something I was doing wrong.

The Gecko's are in a steel enclose with plastic window for seeing the
status and air vents.

The cables are all shielded between the Geckos and the carrage, and
the last foot is not shielded.

My goal would be to listen without the noise, but am also afraid that
just because I can hear the whine, it might effect other things in
the shop. My PC's seem to have no effect. Am I worrying about
nothing ?

If you want to respond, please try to keep it on topic. (I'm hope
that's possible) If there is no way to reply on topic, please
contact me direct.

Dave
