And that same para. does indeed appears in the 4th. ed., page 6.3, right-hand column: that's why I failed to find it.
I didn't find it any reference that I listed: pages 5.7 and 5.8 (crystal-controlled oscillators); pages 6.1 to 6.5 (The Crystal Oscillator); and pages 7.1 and 7.2 (Crystal Controlled Oscillators). Moreover, the book's index, under the heading 'Crystal Oscillators), does not list page 6.3 as containing any reference to 'crystal oscillators'.
At least the RSGB's decision to have references about the same topic, to wit, 'Crystal Oscillators', scattered about in several places, (rather than in one coherent section), plus an inaccurate index, is compatible with the many other technical errors that exist in that book and its predecessors. I've always maintained that the RSGB used the word 'Amateur' a bit too literally!
Yes, I do realise that all of that is quite negative, and it gives me no pleasure at all in reporting my experiences of many RSGB publications that I have read over the years, but for me, I expect my technical reference books (especially those which claim a prestigious authority) to be as reliable and as accurate as quality test equipment. Bad & unreliable information or data from measurements is worse than having no information / data at all: at least in that situation, you can always make an inspired guess!
