Interesting, but from past experience, the results may be just the opposite
a few months later because the source of the components may change over
time.
The components of fluorescent fixtures consists of
The ballast - which is usually outsourced by the fixture manufacturer.
Ballast types vary - GE, Universal, Advance, and several other Ballast
makers sell to fixture manufacturers.
The sockets - usually made by Leviton or Eagle or Rodale - but there are
others.
The lamp (the fluorescent lamp). Usually are not provided by the fixture
manufacturer. Made by Phillips, GE, Sylvania, etc.
Some even have a 'starter'.
--I expect the ballast is the critical component - some are magnetic, some
are electronic - its probably the culprit

GE makes an RFI Filter that can be added to standard 4 Ft Tube Ballasts,
and that will eliminate MOST MF/HF Fixture Interference. I have been
using them in Alaska for years.
