I noticed that my logging programme still recognises the OK4 prefix as being a /MM station. Qso’s with Karel OK4DX/P are not given a country as the OK4 prefix is not assigned in my programm to OK. I know OK4 used to be for /MM but I am guessing this may have changed when OK and OM became separate dxcc countries. I did work two OK1 stations back around 1997 signing /MM, not OK4…/MM.
The online OK call book shows a small number of OK4 stations who are not /MM. Can anyone confirm that OK4 is no longer used for /MM and, if so, the date of the change? The online OK licence doesn’t seem to say anything about it. It would be nice for my logging programme to show Karel in OK when he is /P without breaking the date rules!
