turn it off. If the interference goes away, the MFJ-131RC is causing the interference. Try to
eliminate the interference by reorienting the MFJ-131 RC and/or increasing the separation
between your equipment and the MFJ-131RC. If you cannot eliminate the interference, the

FCC requires that you stop using the clock.
