Thus to demodulate this form of transmission, the carrier must be re-inserted and a suitable detector used such as a balanced detector. SSB sounds like "Donald Ducking when encountered on the air. With the the SSB switch ON and very slow fine tuning it does indeed become intelligable. Some receivers have an LSB and USB switch or equivalent, this stands for Lower Side Band and Upper Sideband as either can be transmitted. Standard AM Broadcast is "Double Sideband Full Carrier" as a comparison. SSB results in more power available for transmission and is a favorite of the Amateur Radio Ops, HAMS. Some Ham Bands to listen to are 3.5 to 4.0 MHz, 7.00 to 7.3 MHz, 14.00 to 14.35 MHz, 21.00 to 21.45 MHz, 28.00 to 29.7 MHz. SSB is generally on the upper portion of these bands. With a good antenna you will be able to receive Amateur Radio Stations World Wide. Best Regards (73) Rod Dinkins AC6V
