Hey Carl,

Are you using the internal battery or connecting it to ships power?

See previous threads here on RAS regarding interference when powering it
from the ships power.


If it is interference coming down the power cable, then it might be
worth
using a ferrite toroid to reduce the interference. The technique is
quick, simple, cheap and non-invasive, but there's also a reasonable
chance
that the equipment already has such filters fitted internally. It will
reduce
both RF interference and also power spikes (the classic example being
clicks on audio amplifiers caused by fridges turning on.

Here's an handy example, but they are widely available.
