When you place a call from a remote radio you simply switch between channels until you find an unused one, and dial the required number. Of the six stations in use, two are set up for automatic operation and four for manual, as there are many older type HF radios in use in the countryside which are not compatible with the automatic crosspatch. As time goes on, and more of the old radios are replaced with modern Telcall-equipped sets, more of the manual base station systems will be switched over to automatic. The same operator, Telecom Namibia, is now also offering a fax forwarding system. Faxes can be sent and received all over the world, and routed via the radio in Walvis Bay to the remote user.
Any organisation can have a radio-telephone system.
The Namibian example is a public access phone system, but mining companies, police forces, armies and government departments, operate many systems. The smallest network has one remote HF radio, one base station HF radio, and one interconnect. The benefits of HF radio do not end with simple voice telephony. Barrett 923 fax and data systems and 960 telephone interconnect have also been designed to allow the non-technical user to install and operate the system. CC Mail and MS Mail are compatible with the system giving a familiar screen to the users of these packages.
