What the thread found

• When a Marell digital level and RF Links video transmitter are connected simultaneously to a Clipper 24 sled, video signal dropout occurs, but each device works without interference when used alone.
• The interference problem may stem from inadequate shielding in the RF transmitter allowing electromagnetic radiation to couple into the digital level or sled components.
• A small internal component in the digital level or sled could resonate at the transmitter frequency or its harmonics, acting as an unintended antenna.
• Installing a video distribution amplifier internally resolved similar interference issues between a digital level, RF transmitter, and recorder when all three were powered simultaneously.
• A Marell digital level can be factory-upgraded with an internal video distribution amplifier to prevent signal interference from multiple video devices.
• Video distribution amplifiers are available in compact form factors such as a 1-to-2 configuration that can be built into a digital level or as standalone 1-to-4 units powered by 9V battery.

Depends on

• The original poster did not complete testing with alternative transmitters or under different physical separation distances before sending the level for factory upgrade.
• The solution was implemented through factory upgrade rather than confirmed through independent troubleshooting steps.
• This is a report from 2007 equipment and may not reflect current product designs or manufacturing practices.
• Specific causes of interference between these particular models were not definitively determined.
