ELAD FDM-S3 SDR Receivers
ELAD FDM-S3 SDR Receivers are outstanding Software Defined Radios with impressive performance features. The Italian manufacturer, ELAD, has pushed the boundaries of modern SDR design with this model. For instance, the FDM-S3 offers an incredible 24 MHz bandwidth that can be scanned simultaneously, allowing up to four receivers to operate at the same time—a feature typically reserved for much more expensive receivers. The FDM-S3 functions as a direct sampling SDR with a variable sampling rate of up to 122.8 MHz. It covers a reception range from 9 kHz to 108 MHz, with an optional downconverter available for even higher frequencies. One of the unique aspects of the FDM-S3 is its variable sampling rate, which ranges from 98 to 122 MHz depending on the band. This flexibility allows for more favorable divider ratios for down-sampling, enhancing sensitivity and dynamic range.
