ERRORS AND OMISSIONS.
Whilst

in the production of

, we can
accept no responsibility for errors,
inaccuracies or omissions contained
within the magazine or any subsequent
loss arising from any use thereof.
Reliance placed on the contents of

urge any reader to take all precautions
appropriate to avoid any loss or damage

.
It should be also noted that patent or
copyright protection may exist in relation
to any items within this magazine. The
RSGB does not accept any responsibility
for failing to identify any such patents,
copyright or any other protection. Readers
are also reminded that the use of radio
transmission and reception equipment
(including scanning) is subject to

ADVERTISEMENTS.
Although RSGB
staff and the staff of Danby Advertising
(its Advertising Agent) take reasonable
precautions to protect the interests of
readers by ensuring as far as practicable
that advertisements in the pages of
RadCom
are bona fide, the magazine
and its publisher, the RSGB, cannot
accept any undertaking in respect of
claims made by advertisers, whether
these advertisements are printed as part
of the magazine, or are in the form of
inserts. Under no circumstances will the
magazine accept liability for non-receipt
of goods ordered, late delivery, or faults
in manufacture. Legal remedies are
available in respect of some of these
circumstances, and readers who have
complaints should address them to
the advertiser or should consult a local
Trading Standards Office, or a Citizens’
Advice Bureau, or their own solicitors.
The publishers make no representation,
express or implied, that equipment
advertised conforms with any legal
requirements of the Electro
Magnetic Compatibility
Regulations 1992. Readers
should note that prices
advertised may not be
accurate due to currency
exchange rate fluctuations,
or tax changes.
R S G B
Key:
The figures represent approximate S-meter readings, whilst the colours represent expected circuit reliability.
Black
equals low to very low probability,
Blue
equals good
probability and
Red
equals a strong probability. No signal is expected when a ‘.’ is shown. The RSGB Propagation Studies Committee provides propagation predictions on the internet at
www.rsgb.org.uk/propagation/index.php
. An input power of 100W and a dipole aerial has been used in the preparation of these predictions; therefore a better equipped station should
expect better results. The predicted smoothed sunspot numbers for February, March & April are respectively (SIDC classical method – Waldmeier’s standard) 54, 51 & 48 and (combined
method) 66, 66 & 65. The provisional mean sunspot number for December was 53.3. The daily maximum / minimum numbers were 86 on 14 December and 18 on 21 December.
