list of addendum sheets for RSGB Books

Advance - The Full Licence Book

Please note that significant changes have been made since the First Edition, which was produced in 2003. That edition is no longer supported.

Instructions on how to amend Second Edition books to Third Edition standard are given below

The current Edition is the Third Edition and updates to that are provided below. These are being picked up as the book is reprinted but there are a number of print runs in use so it is worth checking your copy against the updates below.

Edition 3 updates

Page 9, col 1, Remote Control, lines 2 and 3, The 500mW limit now applies only to Foundation and Intermediate licensees.  Full licensees are limited only by their schedule.  Clearly the general advice not to run more power than required is applicable here too. [This has been included in the 2008/2009 reprint.]

Page 12, caption against top picture should read: ‘This radio is receiving on the output frequency of 70cm repeater channel RU266. What frequency should it transmit on?’

Page 13, the section entitled ‘High Power operating and contests’ should have a mortarboard symbol against it.

Page 13, cols 3, second paragraph, first 3 lines should read ‘The problem is usually one of intermodulation, which is covered in some detail later in the book. The difficulty comes...’

Page 13, col 3, third paragraph, first line should read ‘In the receiver chapter we will learn that...’

Page 17, col 1, first paragraph, line 9, delete the word ‘give’.

Page 17, col 1, second paragraph, line 4, the word ‘inflect’ should read ‘inflict’.

Pages 18 and 19, The EMC committee leaflet 7 on Protective Multiple Earthing (PME) has been reissued. The new version is at http://www.rsgb.org/emc/leaflets.php and should be read in place of the existing text in the book. It is also worth noting that all of the diagrams on pages 18 and 19 are incomplete and the full EMC leaflet should be obtained.

Page 20/21, Readers should note that the EXP key shown and used in the text is now marked 10X on most new scientific calculators.

Page 21, in the example ‘What is the resonant frequency?’, right hand version, line 10, the word ‘micro’ should read ‘pico’.

Page 22 col 2, last 2 lines, the words ‘The resistance may be defined as:’ should be before the formula, not after it.

Page 36 col 1 para 1 - first mortar board. Lines 4, 5 and 6, Replace existing text "twice the supply voltage...." with "twice the peak voltage (not RMS) from the transformer secondary. This is due to the charge on the capacitor adding to the negative half cycles from the transformer."

Page 41 col 1, last word of last line should read 'than' not 'then'

Page 46, col 2, next to last line, after ‘...or frequencies.’ Add ‘Fig 7.5 shows how crystal switching can be used in an oscillator circuit.’

Page 46, col 3 line 6. The reference to Fig 7.2 should read 7.3 [This has been included in the 2008/2009 reprint.]

Page 47, col 1, line 6 should read ‘...but the trimmer capacitors in Fig 7.4 and 7.5 can only pull the frequency slightly.’

Page 49, col 1, under heading ‘Frequency multiplier’, line 5, ‘1992’ should read ‘1982’.

Page 60 Fig 8.14, legend to ‘freq B’ should be MHz not MHx.

Page 73, col 1, lines 6, 7 & 8 of bottom paragraph. Replace ' but may be too high for modern transistor transmitters.' with ', however for transistors the maximum SWR is about 1.5.' [This has been included in the 2008/2009 reprint.]

Page 75, col 3 just below mortar board. Line should read 73/2 = 36.5Ω [This has been included in the 2008/2009 reprint.]

[Only believed to affect 2008/2009 reprint] Page 75, col 3, last 3 lines of text have dropped off bottom of page and not put on page 76. Complete sentence by adding 'angle of radiation and considerably increase the radiation in the horizontal directions, which is where it is wanted.'

Page 86, col 3 top line. Replace 'include' with 'be done'. [This has been included in the 2008/2009 reprint.]

Page 98, col 3 line 11 Replace 'induces a voltage' with 'induces a current' [This has been included in the 2008/2009 reprint.]

Page 100 col 3, above heading Viewing RF and modulation, line should read ‘3x2 = 6V peak or 12V peak to peak’. [This has been included in the 2008/2009 reprint.]

Page 102, col 2, under heading ‘Defining the dB’, paragraph 2, line 3, ‘table 13B’ should read ‘table 13.19’


-------------------------------------------------------------

The following updates or corrections should be noted to the 2nd edition, 2005, of Advance! Once you have completed these updates, see updates to 3rd edition above, but please be aware that figure and page numbers may not be exactly the same.

Page 16, col 2 paragraph 2. The Health Protection Agency has now replaced the National Radiological Protection Board.

Page 16, col 3, para 2, line 3. The frequency range shown should be '10 and 146MHz'. This should be noted as it has formed a question in the examinations.

Page 20, line 2. A pi symbol has been missed out. It should read '...square roots and the value 'pi' (22/7 or approximately 3.142).'

Page 20, 2nd line up from bottom. There is a 'pi' missing from the key stroke list, it should read 1/(4x pi x pi x 1.9 exp...), the calculation needs a pi squared.

Page 27, col 1, line 8. The reference to page 7 should be page 26.

Page 28, col 3, under reactance, line 3. The figure reference should be to Fig 5.15 not 1.15.

Page 45, The component identies have dropped off figure 7.3. The tuned circuit components are L and C, the two feedback capacitors, one above the other at C1 (top) and C2 (bottom). Click here for new diagram.

Page 62, col 2, penultimate line, the number should read 555 not 5555.

Page 66, col 1, shape factor, penultimate line of first paragraph, the text should read 3kHz wide at the -6dB point, insert the - sign

Page 67, col 1, last two lines. The peak deviation for 12.5kHz systems should be 2.5kHz, not 3kHz as printed.

Page 67, col 3, para 2 line 1. To properly tie up with Fig 9.17, the first sentence should read 'If the frequency is slightly below resonance'. The diagram at the bottom of the figure shows a positive output below resonance and a negative output above.

Page 73, col 3, 2nd mortar, line 1 The figure reference should be to Fig 10.8, not 6.8.

Page 87, caption to Fig 12.8, the text should refer to Fig 12.7, not 8.7.

Page 89, Fig 12.11, text in the figure repeats the words 'between the' twice, delete one of them.

Page 90, col 3, line 11, the reference to Fig 8.10 should be to 12.10.

Page 98, col 3, last line. reference to Fig 9.8 should be 13.8.

Page 101, col 2, 2nd line. reference to Fig 13.14 should be 8.14.

Following UK amateur radio licence changes in December 2006 and the Advanced Examination syllabus was changed to reflect this.

The changes will take effect in exams taken after the 1st July 2007.  Should you be taking the examination after this date you are advised to substitute these pages for those in the book:
