When all factors are at their optimum, worldwide communication is possible on a HF radio. At many other times it is possible to make contact across and between continents or oceans.

HF radio unit, can also be used to make telephone calls, for which you will need to subscribe to a direct dial service. Recent advances in technology have enabled email, fax, data and even GPS tracking functions to be possible via HF radio. The trade-off for gaining the ability to obtain free calls from your HF radio is learning how to use it. And for some people, it just isn't easy. The most obvious issue is that you cannot talk and listen at the same time, unlike talking on a telephone. This takes some practise and getting used to.
