Setting up an SSTV StationIn the past, an Amateur Radio Operator operator needed to have dedicated and expensive equipment to be able to transmit and receive SSTV pictures using his amateur radio transceiver.But with the advent of the personal computer, it has become very easy to get on the air using this mode of transmission and reception.Here are the things that you need to have and the steps to take to get going on SSTV - either Digital or Analogue. As a matter of fact these same steps apply when you are setting up your station for RTTY or PSK.What do I need:-1: An HF SSB TransceiverAny HF SSB transceiver with associated antenna and hardware, capable of transmitting a stable, clean, drift free signal on any HF band.
Most modern solid state transceivers fit into this category easily. The use of older tube type HF transceivers is not encouraged, but can be made to work.SSTV is a FULL DUTY CYCLE ( Continuous Key Down) mode.
Some HF transceivers are capable of such operation. Check your transceiver specifications. If your transceiver cannot handle FULL DUTY CYCLE operations, you can still use it for SSTV by reducing the power output to approximately half of the rated RF power output when transmitting.2: A Personal ComputerThere are many factors you'll need to look at before forking out your hard-earned cash for a computer. Things like CPU, memory, hard disk space, sound cards are essential factors to consider when selecting the system.
