To All from PA0SE|
Many thanks to all who replied to my request.
The checklist that can be found at the URL given by John, G4CNN, is a most useful one. I would recommend to print it and stick it to the wall in your check.
The rules given are exactly the same as the ones applied in our country by the editor of VERON magazine Electron and also for the RAE.
It appears that the joining together of figure and unit (5V instead of 5 V) as practised by RadCom is considered improper according to the checklist.
It also strikes me that the asterisk to indicate multiplication, as seen so often nowadays, is not in the list.
A related matter is the kind of symbols used in circuit diagrams. In The Netherlands these are also prescribed for official documents. And for Electron those rules are also adhered to. We are certainly not happy with them. I attach two examples, taken from an RAE. We find the modern symbols for (N)OR and (N)AND gates awful, as compared to the old ones.
A transistor symbol without a circle is not too bad in a simple circuit as attached. But in a complicated circuit one usually tries to find the active elements first and a circle around the transistor certainly helps to make them stand out, but is no longer allowed officially.
