0-10v Lights dimming when using a hand-held radio

Hand-held radios can produce a large amount of RF noise that, depending on the fixture drivers, can be interpreted as resistance and cause a 0-10v system to dim. This is not a problem with the switching control, but instead, with the way the driver is reading that RF noise.

Changing the 0-10v dimming wires to a twisted, shielded pair, grounded at one end of the run, may help alleviate the issue, but this depends heavily on the strength of the RF broadcast from the radio. 

This issue can affect any 0-10v system, regardless of the dimmer switch controlling that fixture.
