This chart is based on the table in,
- Anton A. Huurdeman, The worldwide history of telecommunications, p.144, Wiley-IEEE, 2003 ISBN 0471205052.
A number of errors have been corrected. Huurdeman has "P" as . . . . in American Morse (which should be . . . . .) and "Z" as . - - .. in Gerke's code (which should be . — — .., Gerke did not use short dashes). These corrections have been verified correct by consulting
- R. W. Burns, Communications: an international history of the formative years, p.77, Institution of Electrical Engineers, 2004 ISBN 0863413277.
