RAC Bulletin 2011-004 E - Request for Information, Interference from
Plasma Television Sets.
2011-02-24

According to members of the Niagara Peninsula Amateur Radio Club,
noise and signals originating from Plasma Screen digital television
set are causing considerable interference to their HF activities and
have asked RAC for help. Complaints of this nature require specific
and detailed information before RAC can consider taking this matter to
Industry Canada. To gather this information, RAC invites its members
that own a Plasma Screen television to report their experiences of
interference from such products. Specifically, reports should
describe the make and model of TV, a description of their HF station
and antenna system and the exact nature of the interference (what
bands, what sound etc). Remedies should also be tried and reported
such as using ferrite chokes on power lines cords and signal cables if
interference is detected. Amateurs with advanced instrumentation such
as spectrum analyzers and calibrated antennas should measure signal
intensity levels at given distances; these measurements will add
credibility to our investigation. We also want to know from amateurs
that can attest that operation of their own plasma TV causes no
noticeable interference to their amateur radio operations. All
digital domestic equipment, including Plasma and LCD television sets
must comply with Industry Canada standard ICES 003 (interference
causing equipment standard for digital equipment) to be marketed in
Canada. Alternately, TV sets with tuners may be certified under
Industry Canada BETS 7 standard. Please indicate in any report
submitted that a label on the TV or notation in the manual indicates
it is indeed certificated and compliant under current issues of ICES
003 and/or the BETS 7 standards.

Send reports to Norm Rashleigh, VE3LC, VP Industrial Liaison,
