What is HF/SSB?
HF (High Frequency) is the section of the radio spectrum
between 1.6 and 30 MHz. SSB (Single Sideband) is a form
of radio modulation. HF/SSB combines the characteristics
of HF frequencies with SSB modulation to provide very
efficient, flexible and inexpensive communications.
HF/SSB will enable short, medium and long range
communications over flat, hilly or mountainous terrain -
without the need for expensive re-transmission devices, such
as the repeaters used in VHF (Very High Frequency)
communications. Also, unlike satellite communications,
there is no dependence on a service provider with all the
associated ongoing costs.
In many remote areas around the globe, and in certain
conditions, HF/SSB is the only form of communication
possible.
