Because both your TV set and your radio are
designed to receive signals it is, perhaps, not
surprising that most of the TV reception or
interference problems in this booklet can also
apply to your radio and require similar checks to
identity them.
Check list
Portable sets
- 1. If the set is battery-operated, check that the
batteries are of the correct type, are correctly fitted
and are fresh. If in doubt, fit new batteries
- 2. For Medium and Long Wave. Check whether
better reception can be obtained by slowly
turning the set to a new position.
- 3. For VHF/FM. Check whether changing the angle
of the telescopic aerial improves reception. If the
set has a socket for an external aerial, this should
be used.
- 4. Check whether carrying the portable from room
to room through the house gives improved
reception.
Don't expect high quality reception from the
cheaper portable radios.
Fixed (mains-only) sets.
Modern, fixed sets usually have an internal aerial
for medium and long wave, but have terminals or
a socket for connection of an external aerial for
the VHF/FM band.
1. For medium and long wave check whether
better reception can be obtained by turning the
set through 90 degrees.

2 For VHF/FM best results are obtained by using a
VHF aerial mounted as high as practicable
outside your home. If you already have an outside
aerial, check that it is still correctly mounted and in
good condition.
Quality of reception
Medium and Longwave
The quality of reception on these wavebands may
deteriorate at dusk when atmospheric conditions
cause continental stations to interfere with the
programme to which you are tuned. Other than
making a slight adiustment of the tuning, or
altering the position ot your set to minimise the
effect, there is little that can be done locally to
overcome this type of problem.
Neighbour's television sets can cause interference,
heard as a whistle, and nearby computers may
cause a warbling noise. To minimise the etfect you
should try re-positioning your radio in the room.
VHF/FM
Provided you are in the service area of the VHF
station, the quality ot reception on this band is
generally much superior to MW and LW but, unless
you have a good aerial. the signal may be subject
to variation from reflections from buildings or your
own proximity to the set.
On the edge of the service area an externally-
mounted high-gain aerial may be necessary to
ensure adequate reception.
