This gives you an idea of where the 0R7 in place of 0.7 and other historical notations came about.toggle quoted messageShow quoted text
Printing on components was marginal at best in the 40's and 50's, so letters were
used in place of the decimal point. 4K7 for 4.7K etc as the decimal point would
be missed in printing on the components or smudge or just plain fall off at some
It would be interesting to see where the first ever use of this occurred.
CW ops will sometimes us an R for a decimal point as it is faster to send than a period.
Inquiring minds want to know,
