Red ghosting in the recorded image can be caused by a wireless video transmitter positioned too close to the camera and recorder on a Steadicam rig.
Moving the transmitter away from the camera and recorder, ideally to the bottom of the rig, can reduce or eliminate the red ghosting problem.
Checking and ensuring proper grounding on all video cables and shielding can prevent radio frequency interference from acting as an antenna.
Reducing transmitter power output by 6dB or more on the antenna can decrease interference effects.
Powering the transmitter from its own dedicated battery supply rather than sharing power with other rig equipment can reduce RF radiation into power cords.
Switching to a different transmission channel may resolve interference issues.
Adding a 6dB pad to the antenna output combined with a longer, frequency-specific whip antenna can weaken overall output while strengthening the desired frequency.
Individual transmitter units of the same model can vary significantly in performance, so trying a different unit may solve the problem.
Red ghosting on a DSR 500 can also result from internal camera issues unrelated to wireless transmission, such as capacitor problems in the optical block.

The wireless transmission problem occurred specifically with a Modulous 3000 transmitter on a Sony DSR 500 camera in 2004.
Some operators have experienced this issue while others report their Modulous 3000 units perform without problems, suggesting individual unit variation or operational differences.
The internal camera repair explanation for red ghosting was mentioned as a possibility but acknowledged as potentially unrelated to the transmission issue.
