It would appear that the South African decision to use System I was made long before the TV service started in that country, and probably in the early 1960s.
This comes out of the “Final Acts” document for the ITU African VHF/UHF Broadcasting Conference held in Geneva in 1963, available on-line at: http://www.itu.int/dms_pub/itu-s/oth/02/...01PDFE.PDF.
Therein, South Africa was listed as a System I country, without any qualifying footnotes. (See page 322.)
The Francophone countries were listed under System K*. (Presumably K* later became K’, sometimes shown as K1.)
Another outcome was that UHF TV channelling was to follow the European precedent of 8 MHz spacing and numbering from 21 upwards. VHF TV channelling was to use 8 MHz spacing with a 7 MHz alternative for countries already using System B:
South Africa was listed as planning to use Bands I, III, IV and V, but as already noted, Band I was diverted to other uses before the TV service started.
Cheers,
Steve
