JFE, If you've paid the licence fee, and have a receipt, go ahead and buy the radio, 29Mhz, and CB (27Mhz) fall under the same regulations by ICASA, and you can use the radio without having to produce the licence, as long as you have a receipt, and you pay a yearly licence fee for the use of the frequencies, the 29 Mhz radios come with specific pre programmed frequencies which are used by various organisations, ie Ski Boat, 4x4, and so forth, you just have to select the channel numbers you want the frequencies on.
If you need any more info, PM me, I'm in the Two Way Radio trade.
