The signal is then transmitted "on the air" by way of an aerial. As figure la shows, however, most transmitters are a little more complex than that and contain several com- ponents in addition to the oscillator. Let"s look at the block diagram in figure la. An oscillator signal with a frequency of, say, 4 MHz enters an the behind an SSB receiver a crash course in transceiver technology It is all very well saying that SSB stands for "single side band", but what does it really mean? This article not only explains terms like "side band" and "carrier wave", but also provides the uninitiated with an introduction to transceiver technology in general. Elsewhere in this issue readers are invited to construct their own SSB receiver, but before they...
